Summary: After installing this board with a I5-2500 cpu with Win 7 64 bit - I was plagued by freezes and BSOD several times a day. I swapped out video cards, power supplies, etc. all to no avail. I ran the CPUID Hardware monitor software and found the problem. What was supposed to be +12v on the motherboard was only +9v. This caused all kinds of video driver problems. I returned the board for a refund and ordered a ASUS board.
