Hi there. Ok to try and cut a long story short, i bought a new mobo bundle with a 4.2 ghz AMD duel core processor and a gig of ram, a new hard drive, and a ATI radeon 2400 HD. I had graphic glitches and complete systemn crashes and lockups in game and BSOD's leading to the ati2dvag.dll file (ati gfx driver). crashes and lockups and BSOD's got progressivly worse. I sent back the video card and RAM, they said RAM was fine but video card was faulty, got a new one (same model), same problems. Sent back whole pc, couldnt find anything wrong, so i bought a geforce 8600 GT, no graphical glitches, games dont crash or cause system crashes, only sometimes, such as stalker, on ATI card lasted 10 mins before system lockup, now lasts hours and hours before a crash to desktop, not too fussed. Source games (hl2 ect) sometimes get crashes to desktop with looping sound, valve say paged pool memory issues cause this, followed steps, didnt fix it. Thing is, i have had two blue screens of death since my new gfx card, they only happen in game, the game freezes, both when changing map or server, BSOD flashes for half a second and then pc restarts, check event viewer, minidump was saved, now i cant read these things so im going to post all of them here, there are the ATI video card ones and the new ones with my new gfx card. If you need more information please just ask me, Thankyou very much, regards, Will B PS, the first uploaded minidump is the oldest, last two are with the new video card, thankyou.
