bad driver somewhere or get rid of junk in your system
The original post doesn't provide enough information, nor does the
laconic answer. There are many reasons why the OP's computer could be
having this failure. It would be helpful to look in the Event Viewer
(from the Administrative Tools applet in Control Panel) for clues. That
will help narrow down whether it is a software problem (as in "some
program or process running in the background is crashing) or hardware
problem (as in "computer overheats"). Here are generic troubleshooting
steps:
A. For software issues - 1) scan with current antivirus ("current" means
a version not earlier than 2002 but using updated virus definitions);
2) remove spyware with Spybot Search & Destroy
(
www.safer-networking.org) and Ad-aware (
www.lavasoftusa.com). These
programs are free, so use them both since they complement each other.
You may also want to run the latest CWShredder from
http://www.spywareinfo.com/~merijn/index.html. Always read the
instructions before running a spyware removal tool. Be sure to update
these programs before running, and it is a good idea to do virus
spyware scans in Safe Mode; 3) delete temporary and Temporary Internet
Files; 4) stop unnecessary services/programs from starting with Windows
- see
www.blackviper.com for services info and
www.pacs-portal.co.uk
startup_index.htm for programs info - 5) look in Event Viewer for
clues; 6) make sure you've visited Windows Update and applied all
security patches; 7) run a firewall.
B. For hardware issues - 1) open the computer and run it open, cleaning
out all dust bunnies and observing all fans (overheating will cause
system freezing); 2) test the RAM - I like Memtest86 from
www.memtest86.com - let the test run for an extended (like overnight)
period of time - unless errors are seen immediately; 3) test the hard
drive with a diagnostic utility from the mftr.; 4) the power supply may
be going bad or be inadequate for the devices you have in the system;
5) test the motherboard with something like TuffTest from
www.tufftest.com. Testing hardware failures often involves swapping out
suspected parts with known-good parts. If you can't do the testing
yourself and/or are uncomfortable opening your computer, take the
machine to a good local computer repair shop (not a CompUSA or Best Buy
type of store).
