Ok, this isn't really CTM specific but I just don't know where else to turn. I run Windows XP. Yes, I know, say nothing, I have my reasons for doing so. I keep a reasonable system, Virus scanner kept updated, latest MS update stuff and temp files cleared regularly etc etc. But for a long time now I've had this thing where XP has been crashing when I run programs. Sometimes it's as soon as I run a program, sometimes it can be 20, 30 mins or more after I started running it. It usually happens when I click on something or press a key (IE: It happens as I press something, not just at any old time) but that can be a different thing every time. For example, if IE is being run, sometimes it'll crash when I click on the File menu, sometimes it'll do it when I click on a link in a web-page. After switching XP so that instead of just restarting on a crash, it blue-screens, I get error messages whenever it does it, but these are different almost every time it happens. The most popular ones are regarding g400d.dll and win32.exe (I think .exe, could be .dll or whatever). Often however they are meaningless with stuff like "00000000EX at datestamp 00000000". I sent the computer off to my local techies, who had it 2 days and told me the problem was fixed. So I've had it back for an hour, and the problem has already surfaced twice. No, it's not this new virus, since it's been doing it for months and I've installed the relevant fixes. I'm kinda lost now. Anyone have any ideas?
