Last night I installed a new heatsink (Cooler Master Hyper 212+) on my cousins PC. His hardware is as follows:
Motherboard: Gigabyte GA-Z68A-D3H-B3
CPU: Intel i5-2500k
RAM: Corsair XMS3 8 GB (4 x 2) 1600 MHz, DDR3
GPU: EVGA GTX-460 01G-P3-1371-AR
Power Supply: Corsair TX650, 650W
DVD Drive: LITE-ON IHAS424-98 R
OS: Windows 7 Pro x64
After I got the heatsink on I booted it, and noticed a checksum error in the bios. It seemed to resolve itself, and booted into Windows easily. Once there I check the temperatures, which were good - around 33C at 60C at max load. So, I decided to do a little overclocking. I got the multiplier up to 36 without issue. The next time I was in the Bios I noticed it was in Fail-safe mode. Once I tried to load optimized defaults, that's when the trouble began. From that moment on, it got about 1 second into the windows welcome screen, and then blue-screened. It's so fast that I can't read what's going on. Between installing the cooler and when the blue screen started, I booted into Windows about 5~6 times. The mysterious checksum error did not return after the first time I saw it.
I DO get a post beep, all of the hardware seems to be functioning. I also took the Hard drive and put it in another PC to back up the files, and it works perfectly, so it's not like the HDD failed. Any ideas? Would a startup repair from the Windows 7 disk fix this?
