Hi, BZ. Unfortunately, this isn't enough information for you to get an
answer. It could be hardware or software that is causing this problem.
First, turn off the automatic restart to get the blue screen with the
stop error:
System>Advanced>Startup and Recovery>Settings and under System Failure
uncheck "Automatically Restart".
Write down the stop error you get.
Here are generic troubleshooting steps:
A. For software: 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.security.kolla.de) and
Ad-aware (
www.lavasoftusa.com). 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.
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).
After you've done some troubleshooting, if you need more help please
repost. Be sure to tell us your computer specs (processor speed, amount
of RAM, age of box, etc.), what changed between the time things worked
and the time they didn't, and what you've already done to troubleshoot.
