Other hopefully useful info. I use MS Office Enterprise 2007, Google Chrome, Vipre Antivirus 2012 (I run it regularly), Aida64 Extreme Edition (never used it, can't now because evaluation period over), BurnInTest (installed by the manufacturer, hasn't shown any errors when I run it). I've also got a Brother MFC 8860 multifunction laser printer attached. I uninstalled Daemon Tools Lite a 1 1/2 weeks ago. I've also done a defrag, prebootup disk check--no problems showed up. I've noticed pre-bootup 'Startup Rapair' starts but doesn't complete successfully. When I'm doing normal non-gaming stuff, it rarely ever BSOD's. It seems to only do that when gaming, at the start, during or when I've finished. Like if I stop playing and nothing happened when I was playing, guaranteed it will BSOD within 5 minutes. It also BSODs now and again when watching videos (always use Divx), although not as frequently as when gaming. A couple of times it's BSOD when I ran Vipre. Driving me nuts, this is... as Yoda would say, lol!
