I have a home-made computer with following spec:
Asus A8N Sli-Deluxe Mobo
Inno3D 7800 GT
AMD Athlon 64 X2 Dual Core Processor 3800+
Maxtor 300gb Hard drive
2 gigs RAM (think DDR, cant remember dont kno how to check soz)
Formac 2010 GAllery 20.1 inch LCD
Tascam US-122 Sound Card
Various peripherals, mostly gaming such as
Logitech Cordless Wingman Rumblepad
Saitek Gamers Keyboard
I am running fully updated Windows XP Pro SP2.
I have been having absolutely no problems since it was contructed (January) and I often leave it on through night and day (by accident or virus scanning or downloading etc).
Recently though I started getting the trademark Chipset fan problem of the A8N series. Basically it goes into overdrive and spins at like 8000rpm, doing no damage but sounding like a chainsaw (I thought i had a cable caught up or something), but i thought it was just the chipset getting hot from me leaving it on so much. So i left the computer off for a while came back in a day later and I can't remember if it was immediately or with a few hours delay but I suddenly found Firefox (my faithful browser that has never played up) couldn't open - it gave me the "has performed an illegal operation, send or dont send error message". Even when i reinstalled firefox it wouldnt work, so i had to resort to using internet xplorer which worked fine. Then i installed Pro evolution soccer 5 and Godfather the game, both installed fine but when i tried to play gave the same error message almost instantaneously from clicking the shortcut. I have Ad-aware Professional, AVG 7, Kaspersky Anti Virus Personal (Full), Spybot, TrojanScanner and Zonealarm professional firewall, all fully updated.
So i uninstalled the games, ran all of these programs update and scan commands but came up with nothing. I even booted into safe mode and performed the same trick - nothing (no virus or malware found in any program). I tried reinstalling the games and firefox again and still the same error message pops up. But the weirdest thing is that my previously (from about 2 weeks ago) installed games, even the superdemanding ones, like FEAR, CoD2, Civ 4 and X3 run fine, its jsut these newly installed games and firefox which won't open.
So basically i am left with a computer frozen in time, i cant install any new applications - PLEASE HELP ME! I had to spend £50 on those games and would really like to play them! (plus i love firefox and rue iexplore).
I dont know if the fan problem is related but i stuck it in anyway. I attached my dxdiag if that provides any insight.
Thanks in advance
