I have a biostar gf7100p-m7s DDR2 board with lga775 and I have tried both a core 2 duo e8400 and a core 2 quad q9300 and both are recognized, but the website (biostar) says they aren't supported... I can literally go into bios and OC them.. I put windows installation on a hard drive and it started to boot into it after I set the HDD to primary boot device, then the wheel thing spun around a few times and I got blue screened. Not sure what to think.. I put my old pc back together that plays wow on fair settings and the motherboard is a serious bottleneck, so I really need this to work
