My pc is: CPU: Intel pentium D830 3.0 GHZ dual core Mobo: Asus P5DN2-SLI Deluxe Ram: 2 gb Kit Kingston retail 400mhz video: Winfast Geforce 7800 GTX TDH 256 mb (256bit) hdd: 200 Gb Maxtor 7200rpm 8 mb cache+300 gb Maxtor 7200rpm 16 mb both s-ata2 OS: windows XP SP2 (up to date) For a while now I've been having problems with the system crashing while in games, while watching movies or even when idle. Sometimes upon reboot i recieve no error other times up to 3 messages with windows has recovered from a serious system error message. There is no apparent pattern to the crashes as sometimes i can play games like COD4 for hours without any problems other times i start a movie and the system crashes. It doesn't seem to be an overheating problem because i don't lose system performance at all before the crashing occurs. I have tested my ram and it is ok, (for now my pc is still under warranty) the techs from where i've bought the PC say they found nothing, but still the problems occur. I have tried just about everything but nothing seems to help (i used to suspect that my mobo or ram were at fault but i am not so sure now). I have attached the most recent minidumps for more information just ask.
