Hello, I have received the BSOD on my computer numerous times over the past few years. I build the computer about 4 years ago with a friend and even after having reformatted at least 5 times I will still get it. I have used XP 32 and 64 bit and Windows 7 32 and 64 bit. My System Information is: System Manufacturer: Nvidia System Model: nForce 680i SLI LT BIOS: Phoenix - AwardBIOS v6.00PG Processor: Intel(R) Core(TM)2 Quad CPU @ 2.40GHz (4 CPUs), ~2.4GHz Memory: 4096MB Ram DirectX Version: DirectX 11 I figure the reason my computer gets the BSOD is because of hardware, since even after reformatting yesterday to Windows 7 64-bit it had the BSOD this morning. Any help would be appreciated! Edit: I went through all of the troubleshooting and the only thing that might be a problem is the power supply. I downloaded the SpeedFan program that was in the troubleshooting section and when I ran it I got these results: Vcore: 1.19V +12V: 9.82V AVcc: 3.20V I also noticed when running SpeedFan that my Speed02 was at 67% while all my other speeds were at 100%. Does this mean I need to purchase a new power supply or is this normal?
