Hi guys, I built a system for a friend about 2 years ago, but he's been having blue screening problems ever since plus problems extracting .rar files. Original System: Q9300 Intel Quad-core CPU Gigabyte GA-N650SLI-DS4L mobo 2x BFG 9600 GeForce cards 650W Coolermaster RP-650-PCAP PSU 4Gb Corsair 800Mhz DDR2 RAM Western Digital SATA2 500Gb HDD DVD Drive CDRW drive. Vista SP2 Home Premium Since then, we've replaced the mobo and PSU to: Asus P5N-D Corsair 950TX Voltages and temps have always been fine. Steps taken so far: Tried using only 1 graphics card at a time. Tried using a different graphics card. Tested each stick of RAM individually. Tried different RAM Bench-tested system Disconnected IDE drives. Bought a different HDD Bought another motherboard (which was faulty and had to be sent back). Tried different Power lead Even tried different keyboard and mouse. Tried different monitor Tried linux boot disk Cleaning and reapplying thermal paste. The thing is, with the old motherboard, it works, but it BSODs, but with the new motherboard, it will only get onto desktop and freezes after a few minutes. It'll even freeze in BIOS. Just looking at temps, and it'll freeze as soon as I touch the keyboard. I've also noticed that the temps on the new motherboard are higher than I'd like (low 40s degrees for a socket 775 processor???). So, what you reckon it is? There's little else I can even think of testing apart from CPU. Any ideas would be greatly appreciated. Thanks
Have you tried a fresh install of the OS? could be a kernel fault. you could also try a different bios revision. Also try increasing the Vcore voltage in the bios by about .1 could well be stability issues.
