hi Eveyrone, just purchased a new cross hair v. I switched everything from my existing crosshair iv. Everything was working fine before. I have an AMD Phenom II, G Skill Ripjaw DDR3-1600 (4gbX3), Evga 580. Updated the bios to most current. I tried numerous things with the ram; 1 stick at a time things like that. As soon as it starts to load windows it has a BSOD. I can pause the screeen to read the error. Bios is in default settings. Anyone have any ideas?
