GENERAL TROUBLESHOOTING
Symptom: The system's fan
is whining loudly.
Solution: A loud fan can be the result of a number of
minor problems. The common cause is dirt. A dirty fan,
clogged with dust, is highly inefficient and works harder to
handle its cooling duties. As the fan struggles to cool the
system, it produces the whirring sound. A quick cleaning
should do the trick. If the fan is new and you're still
hearing a loud whirring, your problem may be "ambient heat."
You need to operate your PC in a cool environment. Many PCs
get louder as they get hotter, with the fans spinning faster
to keep the system cool. Be certain your PC is clean and
cool and you'll run trouble-free.
Symptom: Your PC spontaneously reboots.
Solution: A long-standing mystery solved! If
rebooting occurs in a PC that you've just built, try
re-seating your CPU's heat sink. Make sure you're using the
proper thermal gel and spread it evenly between the heat
sink and the processor. If inadequate amounts of gel have
been applied or low-quality gel has been used, the system
will reboot as the CPU heats up---and builds in the uneven
"pockets" created by the uneven gel. Also: check to see if
you've removed the protective sticker on the bottom of the
heat sink (don't laugh---it happens!). And by all means,
make sure your motherboard supports the CPU you're
installing. If these steps check out and you're still
experiencing spontaneous reboots, your problem may be one of
the following: Overclocking: We do not recommend
overclocking. Memory Timing: The fix? Go into your BIOS and
set your memory on "Auto" or at a more conservative setting
and see if the reboot problem goes away. Oudated BIOS: Make
sure you have the latest BIOS for your board. You can
determine if your CPU is supported by browsing the BIOS
updates of the motherboard's manufacturer. If you're running
a Pentium 4 Extreme Edition and notice that it's only
supported with the latest BIOS updates, you may have located
the problem! Inadequate Power: If you've made significant
component upgrades---with the exception of the power
supply---your power supply may be overstressed or failing
due to heat or age. Finally, if you've migrated your OS and
other files from machine to machine to machine, it may be
time for a clean install.
Symptom: Your Optical
Drive (CD or DVD) Runs Slower and Slower....
Solution: Again, the villain may be dirt, since
optical drives rarely "slow down" on their own. Optical
drives either work---or they don't, so a mechanical problem
is ruled out. What most likely has happened is that your
dive has accumulated a layer of dirt or dust. Here's the
fix: You'll need a can of "spray air" (available
everywhere). Eject the disc tray and spray into the drive
with short bursts---and be sure to spray at an angle so the
dust will be expelled out of the drive. Do not spray
continuously or turn the spray can upside down (doing so
could introduce moisture into the drive. Repeat this process
a few times, then try test the drive.
Symptom: I have four pieces of RAM installed and I'm
pretty sure that at least one is bad. What's the best way to
test RAM for errors?
Solution: Since you have four pieces of RAM, you can
install just one DIMM in your motherboard at a time and run
the machine until it crashes. This isn't a completely
reliable way to test RAM, though. As an alternative,
download Memtest86 (www.memtest86.com) and create a bootable
CD. Memtest86 does a fair job. It runs several test patterns
through the RAM. If a piece of RAM passes these tests, swap
it with another DIMM and continue your tests. Even better
than Memtest86 is Ultra-X's RAM Stress Test Pro 2, which is
a self-booting diagnostic plug-in card. This card uses a
comprehensive set of test patterns to assess your memory,
and we've found that it finds bad pieces of RAM that other
testers miss. Keep in mind that it may not actually be a
stick of RAM that's bad. The problem may in fact be a bad
DIMM slot. If all four pieces of RAM pass the test, you may
have to rerun them in each individual slot on your
motherboard. Finally, your motherboard's BIOS usually sets
RAM timing by reading the SPD setting on the module. If the
SPDs are set too aggressively (we've seen this), it may
cause problems. You should consider going into the BIOS and
manually tweaking settings such as your CAS latency to a
more conservative setting.
Symptom: Sometimes when I
play games for a long time, my computer just randomly
crashes to the desktop.
Solution: Random crashes in games can be the result of a
few different problems. Typically, it's a heat issue, a
driver issue, or a problem with the game. The first thing
you should do is check for a patch for any of your games
that are crashing. It seems like common sense, but
frequently we receive complaints from people trying to run
games that have been patched three or four times. Once
you've updated your games, you need to update your videocard
and chipset drivers. Get you videocard driver from the
company that manufactured your card's chipset, either ATI or
nVidia. You should also check for newer drivers for your
motherboard's chipset whenever you update your videocard
drivers. Outdated motherboard chipset drivers are one of the
main causes of general system instability. If you've updated
all your hardware, but are still having problems, you may
have a heat issue. Open your case and look at your AGP card.
Is there another card right below it? If there is, you
should consider moving that card to another slot. A card
directly below a high-end videocard can disrupt airflow
enough to cause overheating issues with today's
top-of-the-line videocards. If freeing the neighboring slot
doesn't alleviate your problem, try adding a fan that fits
into one of your PCI slots and exhausts hot air from the
bottom of your PC.
Symptom: My new Athlon XP
system is telling me that my brand-new Athlon XP 3200+ is
only any Athlon 2200+!
Solution: It sounds like your motherboard's bus speed
is set incorrectly. You see, you probably bought and Athlon
XP 3200+ that runs on a 400MHz bus (which is actually a
double-pumped 200Mhz bus). For the motherboard to recognize
the CPU as a 3200+, the CPU has to run at 2.2GHz, or
2,200MHz. The CPU reaches that speed only if the motherboard
is set to an 11 multiplier and with a 200MHz bus. So,
11x200=2200. If your motherboard's frontside bus is set to
run at 166MHz, the CPU would boot at 1833MHz. It's no
coincidence that this is the same speed at an Athlon XP
2200+. To correct this, reboot your machine and go into the
BIOS by hitting DEL or F2 during boot. Look for the section
that lets you change the bus speed. Hopefully we're right
and it's set for 166MHz. Increase it to 400MHz, save the
settings, reboot and you should have a 3200+.
Symptom: My optical drive
has suddenly slowed to a crawl reading discs, and it refuses
to read some discs.
Solution: Optical drives usually don't expire
gradually; most simply stop working without so much as a
death rattle. It's much more likely you drive's lens has
accumulated a layer of dust.
Get yourself a can of compressed air at the local geek
emporium, and eject the disc tray. Spray into the drive with
quick, short bursts at an angle (so the dust is more likely
to be expelled from the drive). Do not spray continuously or
with the can upside down, because that could introduce
moisture into the drive. Give the dust a minute to settle,
and spray the innards again.
Symptom: I just bought a
new PC, and now my PocketPC refuses to connect via the USB
port.
Solution: This is a common issue. You'll have to buy
a new PocketPC. Just kidding. This problem occurs if you
plug your PocketPC in before installing ActiveSync. Check
the Device Manager by right-clicking My Computer, selecting
Properties, clicking the Hardware tab, and then selecting
Device Manager. If you see an Unknown Device entry, delete
it by right-clicking it and selecting Uninstall. Restart you
PC, install your PocketPCs drivers from the manufacturer's
disc, and plug it in again.
PC AUDIO AND MP3S
Symptom: I'm only getting
sound out of one speaker.
Solution: This usually happens when the mini-jack
coming out of your speakers us not fully plugged into the
soundcard input slot. Reversed polarity of a speaker can
cause some of the weirdness as well, so make sure the
positive terminal on the actual speaker is connected to the
positive terminal on the subwoofer (or wherever the speakers
connect to the amplifier), and vice versa for the negative
terminals. One final possibility: Pet owners should
routinely check speaker cables for teeth marks and replace
the cables when Mr. Bigglesworth eats through the outer
layer.
Symptom: The remote
control for my PC speakers suddenly stopped working the
other day. I installed new batteries but it still won't
work. Is it dead?
Solution: Probably not. It sounds more like a
sleeping remote. To wake it up, simply remove the batteries
and press every button on the remote in a sequential order.
Then just replace the batteries and your remote should work
again.
Symptom: Sometimes I'll
rip a worn CD, only to find later that some tracks have
skips in them.
Solution: This is a common problem, and can be easily
fixed. Go to www.exactaudiocopy.de (don't worry-the site is
in English). We've brayed about Exact Audio Copy before, and
here's why: When Exact Audio Copy rips audio it
double-checks that data for accuracy, and if it detects any
discrepancies between the original and the rip, it will
extract the data again and again until it has determined
that the result precisely matches what's on the disc. If the
error correction is unable to compensate for a flaw in the
disc and the data is irretrievable, Exact Audio Copy will
let you know, sparing you from unpleasant surprises later.
Oh, and did we mention Exact Audio Copy is free? Life is
good.
Symptom: My Creative Labs
Jukebox Zen Xtra keeps crashing. Is it broken?
Solution: If a single bit in an MP3 file is out of
place or errant for any reason, it can make many MP3 players
lock up or crash. You'll know this is the case if your
player crashes on the same track every time. If so, you'll
have to remove or re-encode the track. If an errant track is
not the problem-you'll know this is the case because it
won't crash on the same song/s-you may be able to
rehabilitate your player be reformatting the drive. You'll
find instructions at the Creative Labs web site. Go to
Support, click Portable Audio, and select "Troubleshooting
the Nomad Jukebox 3 as a Standalone Unit" (also known as
Solution ID #7392). Reformatting will delete the contents of
your player, of course, so make sure you have all your music
backed up before you go for it.
Symptom: I can burn audio
CDs and listen to them on my PC, but my portable CD player
and car stereo can't recognize them.
Solution: Commercial CDs are literally stamped from
extruded masters, creating pits and lands that CD players
have been designed to read. Burned CD, however, create
darkened areas that mimic the pits and lands of commercial
CDs. As you've noticed, not all players-especially older
ones-can deal with these kinds of discs. But all is not
lost. Your best bet is to burn at a slower speed, 4x or
below. This creates slightly more prominent differences
between the burned and non-burned areas. If you have a
Plextor burner, though, you have an even better option. The
bundled Plex Tools includes VariRec, which allows you to
subtly alter the burning strength of your optical drives
laser. By experimenting with various discs and burning
strengths, you will almost certainly find the right
combination for your CD player. VariRec is supported by both
Nero and Easy CD Creator. We've used it to make audio CDs
playable on otherwise uncooperative boom boxes.
PC BUILDING TROUBLESHOOTING
Symptom: I just built a
new machine and am experiencing totally random crashes. What
are the possible culprits?
Solution: Random crashes are always hard to diagnose,
so let's cover all the bases. The first area to check is
your drivers. Make sure you have the latest drivers for all
your hardware, especially the motherboard chipset drivers.
You should also make sure you've downloaded all Windows
Updates. Next, consider your power supply. If you're running
a midsize 300-watt PSU, and upgraded to a late model Pentium
4 CPU or Athlon FX, or are just running several hard drives
and PCI add-in cards, you should upgrade your power supply
to a 400 watt or thereabouts model. Inadequate power to your
components can cause the entire system to lock up at worst,
or just cause certain components to malfunction or stop
working. The final consideration is cooling. Ideally, you
should have a decent size fan in the lower front of your
case sucking in cool air from the ouside, and a large
exhaust fan above your AGP card pull air out of the case.
Symptom: I'm building a
new PC and have the motherboard mounted inside the case.
When I push the AGP card all the way down in the slot, the
end of the metal tab on the slot cover hits the bottom of
the case, preventing me from inserting the AGP edge
connector all the way.
Solution: Even though every ATX motherboard and ATX
case should be exactly the same dimensions, there are still
small variances that can create problems when transplanting
your hardware into a new environment. It's fairly common for
the videocard to not quite fit, and when this happens the
solution is to simply bend the end of the metal slot cover
away from the board ever so slightly. This will afford it
the extra millimeter or so of clearance the card needs to
fit all the way down into the slot. But be careful!
WIRELESS (WiFi) NETWORKING TROUBLESHOOTING
Symptom: My wireless
laptop will not connect to my wireless router. It can't even
see it!
Solution: Usually Wi-Fi connection problems are the
result of configuration errors, incompatible firmware, or
interference with another router. It's easy to fix firmware
issues-all you need to do is download the latest firmware
for your wireless router manufacturer's web site. If you've
installed the firmware update and still can't connect, your
next step is to temporarily disable WEP or WPA. If you can
connect to the router when security is disabled, check all
your WEP settings. You need to use exactly the same key on
your router and any machines that connect to it wirelessly.
Also make sure the Authentication Type on each of the PCs
matches the setting on the router. Troubleshooting
interference issues is more complex. First, you should move
your router off of the default channel. Most routers shipped
today are set at channel 6 be default, and the sheer traffic
can create a lot of interference. You should also uncheck
the field that says, "Automatically connect to non-preferred
networks"-there is no advantage to the feature and it can
cause your computer to behave erratically if you're in the
proximity of the other networks. If you're still having
problems connecting, there may be a hardware problem on your
laptop. Check Device Manager and make sure there isn't an
exclamation point beside your Wi-Fi card. You should also
try connection to another router that you know works
properly. Finally, try connecting to your network using the
same settings, but a different brand of Wi-Fi card.
If all else fails, contact your router manufacturer's tech
support line. You may actually have a faulty router.
Symptom: My broadband
connection feels like it's downloading really slow.
Solution: Sadly, there isn't much you can do to
improve your broadband connection's performance without
spending more money to upgrade your existing service. Sure,
there are a whole lot of products out there that claim to
"improve your broadband speed" but we don't know of anything
that actually works.
If your performance is significantly slower than the
advertised claims of your provider, you should complain to
your ISP. For services advertised as full-speed, we expect a
minimum of 50kB/s download speeds and prefer to see our
speeds top out over 100kBs. If you are paying for a
high-speed broadband connection, but are seeing less than
50kB/s downloads, you should switch ISPs!
Symptom: I can't see the
other computers on my home network from my laptop. What can
I do to make it work right?
Solution: First, you need to make sure that each
computer you want to connect to belongs to the same
workgroup. Open the Start Menu and right-click My Computer.
Go to Properties, then Computer Name. If your workgroup name
doesn't match, you can change it by clicking the Change
button. Some versions of Windows only show the computers
that actually have shared folders or printers, so make sure
you have at least one folder shared on every computer you're
trying to connect to. The next step is to disable your
firewall. By default, most firewalls block the ports used by
Windows networking, keeping even legitimate users-like
you-from connecting to your machine. If all your machines
use the same workgroup and your firewalls are disabled, and
you're using a wireless router, your problem could be the
router. If your wired machines can all see each other, but a
wired machine can't see a wireless machine, it's almost
certainly the router's fault. Barring a firmware update that
fixes the problem, there's no easy way top connect your
machines if this is the case. Check with your router
manufacturer for a newer version of the firmware. If that
doesn't work, you may need to get newer hardware. Here's one
last tip: You can try to connect to your computer's specific
IP address instead of its name. To find the IP address, go
to the Network Connections control panel, right-click your
network card, and select Status. The IP address is on the
Support tab. Once you have the IP, you can go back to your
other computer and put //IP.address.here/ into Explorer. If
you have shared folders on the PC you're trying to connect
to, they should pop up immediately.
HARD DRIVE TROUBLESHOOTING
Symptom: I just got a new
Serial ATA hard drive, but when I try to load the image of
my current drive onto it, the drive-imaging software doesn't
recognize my new hard drive.
Solution: This is a problem that has vexed us as
well, and it comes down to the fact that most drive-imaging
software programs don't recognize Serial ATA controllers and
therefore won't let you image the drives connected to it.
We've tested practically every imaging program on the market
in the Lab, and the only one that successfully moved an
image to a SATA drive and made it bootable was Symantec's
(formerly Powerquest) Drive Image 2002.
Symptom: I just plugged in
a brand-new hard drive but it's not showing up in Windows
XP.
Solution: All brand-new hard drives are sold
unformatted and thus don't show up in Windows until they've
gone through the formatting process. To get up and running,
connect the drive, boot your PC, and at the Windows desktop
right-click the My Computer icon and select Manage. Click
Disk Management in the left-hand tree, and every drive
connected to your system will show up. Simply right-click
your new drive and select New Partition. Then follow the
steps to get your drive up and running.
Symptom: My system
crashed, and when I rebooted, my RAID array was no longer
working properly.
Solution: RAID arrays can stop functioning for
several reasons, but it's usually a case of a cable coming
loose or something in the BIOS being reset. Serial ATA
cables easily come out of their drives, so check them first.
If everything is connected properly, you should also check
to make sure that the ports your array is plugged into are
set to "RAID" rather then "IDE." Because these ports often
double as either standard IDE ports or RAID ports, they must
be set in the BIOS to one or the other. Be sure to check
here first if your array suddenly disappears.
WINDOWS XP TROUBLESHOOTING
Symptom: My computer is
acting odd. Loads of windows open all the time, and I'm
getting a bunch of popup windows that don't look like
Internet Explorer windows.
Solution: Your problem is most likely caused be
incoming Messenger service messages. In a networked
corporate environment, Messenger is used to send time
sensitive messages about server outages, and software
updates, but there's really no reason to leave Messenger
running at home. To disable it, go to Start, Control Panel,
Administrative Tools, and then Services. Scroll down to
Messenger, right-click it, and select Properties. Change the
Setup Type to Disabled and then press OK.
Note that this Messenger service is different from Windows
Messenger. You can disable this service and still receive
instant messages!
Symptom: A couple of days
ago, my computer began behaving very oddly. The disk runs a
lot, even when I'm not using the computer, and my browser
home page is reset to a site I've never been to before.
Solution: This sounds like a classic case of spyware
infection. There are two apps we recommend for combating
spyware: Spybot Search & Destroy and Ad-Aware. You can
download Spybot from www.safer-networking.org and get
Ad-Aware from www.lavasoft.de. Both applications scan your
hard drive for potential spyware and will hep you reomove it
if detected. We recommend using both apps, because sometimes
one application will detect a new spyware program that the
other won't. If one of the applications detects spyware on
your PC, it will either automatically remove it, or give you
instructions that allow you to remove it.
Symptom: My e-mail
frequently stops working-it often stalls when receiving and
sending. And no matter how many times I change the e-mail
settings, it reverts to "localhost."
Solution: There's an outside change the problem could
be a virus, but the most likely culprit is your antivirus
program or your spam filtering program. These apps work by
situating themselves between your mail program and your
e-mail server, then taking a look at every piece of mail you
receive. But if one of these programs crashes or needs input
from you, it will hold up the e-mail download and your mail
program will think the connection has died. If this happens,
just restart your antivirus program and spam filtering
program and try downloading messages again.
Symptom: I keep losing
menu options in Microsoft Word.
Solution: Our bet is that you really like to use em-dashes.
The default keyboard shortcut for an em-dash is Ctrl+Alt+the
numpad Dash, but people often mistakenly press Ctrl+Alt+ the
Dash on the primary keyboard, which is the default keyboard
shortcut for "Remove item from the menu." After you call up
that shortcut, your cursor will change to bold minus sign
and the next menu or shortcut you click will disappear from
Word. The solution? Don't use so many em-dashes!
Alternately, you can remap the em-dash shortcut to something
a little more convenient. Go to Tools, Customize, Commands,
and then click the Keyboard button. Then, under Categories,
scroll down to Common Symbols and click Em-dash in the right
pane. Change the hotkey to whatever you'd like. We like
Ctrl+M. To get back the menu items that you've lost, go to
Tools, Customize, Commands, and drag the elusive commands
back into place.
Symptom: I keep
accidentally e-mailing my friend at her old address because
the program created a shortcut for me.
Solution: This is an easy fix. When you're typing the
name into your To: field, scroll up and down until you get
to the one you want to delete. When it's highlighted press
the Delete key and it will be gone forever!
Symptom: I get a ton of
spam every day.
Solution: There are a couple of really good, free
anti-spam utilities available today-SpamPal
(www.spampal.org) and Popfile (popfile.sourceforge.net).
They use slightly different approaches, but each can reduce
your spam intake by up to 99 percent. SpamPal analyzes every
e-mail you receive and compares the path it took across the
Internet with the servers and IP addresses of known
spammers. It's very effective right out of the box, but if
you frequently receive e-mail from countries where spam is
known to originate, such as China, Russia, and Taiwan, or
from webmail services like Yahoo, which are frequently
abused by spammers, you may see a lot of false positives.
On the other hand, Popfile uses a technique called Bayesian
filtering to determine which letters are spam based on the
content of your e-mails. Every time you mark a message as
spam, the contents of the message are added to the database.
This is highly effective once the filters are fully trained,
but it can take several weeks of flagging each incoming
message as spam before you start seeing greater than 90
percent accuracy. |
