I've had my computer for about 10 months now. I've recently set the harddrive to slave since I bought a new SSD (Corsair Force 3 60 GB), which that worked out fine. Then I installed an Corsair H50 and decided to do some overclocking. Here's my current set-up:
AMD Phenom II X4 965 @ 3.4 GHz | ASRock 870 Extreme3 | Corsair H50 Water Cooler
Samsung Spinpoint 1 TB @ 7200 rpm & Corsair Force 3 60 GB
EVGA GTX 460 (Fermi) 756MB | Corsair XMS3 16 GB DDR3 (8GB at 1333, 8GB at 1600) | Antec Nine Hundred
Ever since I tried to stabilize at 3.8 GHz, it started freezing windows and sometimes BSoD, so I set it back down to 3.6 and 3.4; same thing was happening. These freezes and BSoDs happened anywhere between 30 minutes and 10 hours of turning on the computer.
When I run a PC-Check in the BIOS, it always freezes at checking the Memory (specifically the Module Seating).
