You have me confused here:
Hey im back had to buy a 30$ real slow p4 256mb ram pc of craigslist for now.
Are you saying you added more RAM to the computer with the problems or you bought another computer?
Pc specs
AMD athalon (tm) XP 2600+
1.91 ghz 768 of ram
2 80 gig hitachi hardrives
windows xp service pack 3
These are the specs of the problem computer? This isn't much RAM. How many ram card slots are on the computer?
I honestly don't believe this is a virus/infection problem. I think you would be better off posting all this hardware info in the HARDWARE Section of daniweb. I certainly am out of my element in that and there are experts there who can certainly advise you. But include ALL of your computer specs. You can tell them we have pretty much ruled out infection over here. I just don't think that is your problem, especially since this has been going on since 2007. Just the time frame alone makes me feel this isn't an infection issue, you would have had many more symptoms than just random shut downs.
