I am having trouble with my new graphics card in my new pc build. I have; Mobo - Asus PT6 Deluxe v2 PSU - ABS Tagan BZ Series BZ900 900W ATX12V CPU - i7 2.67ghz OS - Windows 7 64bit Eval Copy Build 7100 Video Card - Geforce GTX 260 Memory - 12 gigs of ddr3 1333 The problem is that even with the newest driver out for windows 7 64bit installed, my pc locks up on the boot up screen shortly after it asks my for my password. I can then boot it up in safe mode fine. When I disable the video card in safe mode, and reboot in normal mode it works fine also. It just locks up whenever the graphics card is enabled even with the newest driver. Please help! Thanks!
