Hi there, I appreciate anyone who takes the time to read this, I am at an absolute loss. System MB: Asrock N68C-S UCC CPU: AMD 64 X2 6000+ (Brisbane) RAM: Kingston HyperX 1066 DDR2 HDD: Samsung HD321 320GB GPU: GeForce 9500gt PSU: Arctic Power 700W The BSOD still occurs with absolute barebones connected, using on board video. The machine usually has another HDD connected and a PCI USB card, they have been removed along with the GPU while I try to work this out. The BSOD first occurred while I was playing Portal 2, which upset me. Now I can force it to blue screen within 15 minutes using the CPU stress test in AIDA64. FurMark will happily run for hours without crashing the machine while the 9500GT is connected. Core temperatures according to speedfan and AIDA64 stay below 60 at all times, even when stress testing (up until it BSOD's). I have tested both sticks of RAM in both slots, 7 passes with Windows memory diagnostic without an error. Updated any and all drivers, deleted old video drivers and reinstalled from the nvidia website with v270.61. STOP messages I get are 0x1E and 0x0A. I have attached my last few minidumps, I looked at them with WhoCrashed but it reports a software problem in an unknown driver. The only thing I can think may be causing the issue is the power demands of the CPU. My motherboard supports up to 95W. In theory my CPU is 89W max, however I know that the same model was available as 125W (Windsor), and I don't know how reliable their labelling may be. AIDA64 does report it is a Brisbane though. I may seem to be clutching at straws but I am completely out of ideas. Anything anyone can offer as advice would be greatly appreciated.
