PC Troubleshooting
Q: Why do computers crash (or why isn't my
machine working right)?
A: All computers crash. It's just a matter
of frequency. All computers have problems. It's just a matter of the
severity.
Step 1: If your machine is giving you trouble, first try a
reboot with Ctrl-Alt-Del. In many cases, the problem
disappears after a restart.
Step 2: If rebooting the machine doesn't
work try powering down and waiting 30 seconds.
If either of the above solves the problem, it
probably isn't serious and most likely will not come back.
Step 3: If you still have a problem, the
next logical step is to do some detective work.
Ask the following questions
first:
- When did the problem start (or when did you
first notice it)?
- Was the computer changed in any way around
the time the problem first appeared? (Was it moved, or was
something added or taken away?)
- If anything changed, try to undo it and see
if the problem goes away.
- If you don't know what changed (or if nothing
changed) then try to isolate "where it hurts" and "when it hurts"
and then simplify.
Is it hardware?
- If the machine doesn't power up...
- Is the device getting power? (Lights? A
slight humming sound?)
- Ensure that the outlet is
live.
- Ensure that all external cables are
firmly connected.
- Ensure that all external cables are plugged
into the correct ports.
- If the monitor is dark, adjust brightness
and contrast. If that doesn't work, try substituting a
different monitor.
- If the machine powers up but you can't boot,
it could be a hard drive problem.
- If the date and time are always wrong it's
probably a battery problem.
- If you physically disconnect (not just turn
off) all peripheral devices, does the problem go away?
- If everything outside looks ok, open the
case
- Ensure that internal cards all
seated.
- Ensure that internal cables are
connected.
- Ensure that RAM is seated
properly.
Is it software?
- Was any new software installed?
- If so, remove it and see if the problem
disappears.
- Was someone new using the machine?
- Could they have changed an important
setting?
- Is the problem system-wide or does it only
appear in one program?
- If system-wide, look at the Operating
System
- Check the Device Manager for
problems
- Update video driver
- Update sound driver
- Update network card driver
- Check to see if the hard drive is
full
- Reinstall Windows
- If one program only, look at that
program
- Check the program's preferences or
custom settings
- Check for an update
- Call the publisher
- Reinstall the program
Tips and Tricks
- Press escape when booting to see the status
and any error messages.
- Press F8 when booting to get various boot
options.
- Pressing F5 when booting will automatically
boot in "safe mode".
- If your system seems to hang press capslock or
numlock and see if the light goes on (or off). If it does then you
may not really be stuck.
- If you install and uninstall many programs on
your computer on a regular basis you may notice that Windows
begins to slow down. You may need to reinstall Windows from
scratch in order to fix this.
