Hello their, i'll get right to the chase, I basicly signed up here because for the first time I can't seem to figure out whats casuing my pc to freak out. Even the way my BSOD's are aquring makes no sense to me. I'll start with my PC specs before I'll give the story of my history of wierd BSOD's. Power Supply : Corsair TX650W OS : Windows 7 64bit Ultimate edition Motherboard : Asus M3N78-VM Processor : AMD Phenom X4 9850 Black AM2+ Ram : 2x2 GB Ram DDR2 1066 MHz kit Videocard : Asus (ATI) EAH4870 DK/HTDI/1GB5 Hard Disk : Some 16mb 500g Sata drive from Samsung My BSOD's started about 2 weeks after I got my pc back from the shop. Motherboard was broken (southern bridge I believe, SATA's drives where inoperative). When I got it back, everything was working fine at start. Reinstalled, updated ect ect... I was quiet happily playing games again. But then BSOD, this after AVG 2011 Free had installed a important update requiring a reboot (so it prolly did something in my reg or something). So I deinstalled it, and went on to playing games again. 2 days without BSOD while using my system intensivly. Then on the third day, BSOD again! So I thought to myself, seeming I never had driver conflicts before because I keep the up to date, maybe something F-up after installing when I got my pc back from the shop, so I completly reinstall windows 7, and now thinking, hey it's not AVG after all reinstall that aswell. A week goes by with my system running smoothly, then out of the blue BSOD, Again after AVG updates, so uninstall again. 2 / 3 days go by without a problem then, suddenly BSOD! totally confused I started googling for BSOD errors in windows 7 64bit and checking if people had similiar systems to mine. I finnaly found a case where Nvidea drivers might be causing issues (I seem to have something onboard on my Motherboard that is from Nvidea and indeed windows update had downloaded and install some nvidea drivers). So I deinstall these, seeming its not really hindering my system preformence if I did. Again 2 or 3 days which my system runs just fine again. And again BSOD, now having tried almost everything I know of, Knowning almost for a 100% that my drivers are up to date and accurate, i'm left pondering what the hell is going on. The most annoying things is these BSOD are happening at random moments without any patern. So it's extreemly hard for me to know for sure if I got the problem or not, and i'm not that gifted in reading and understanding error reports. One thing too note is, I've yet too expierence a BSOD while outside of a game. Dumpfile (from minidump) can be found below, any help would be appreciated. I also appear to have a larger dump file in my main windows folder called MEMORY.DMP which is roughly 37 MB big, just hollar if you want me to upload that aswell. Sorry dat alles zo raar eruit komt, dacht dat de vertaler mijn engelse post wel aan kon --'
