I just bought today a Asus P8Z77-V LE iZ77 for my system, everything working just fine if i use the onboard VGA. When i assemble my Ati x2 HD 3870 on the primary PCIE my system just doesnt start, i got a bip and that's it... Although if i put my graphic card ont he secondary PCIE everything works just fine. I've tryed like everything i can think off and i still have the same issue. Anyone has any idea? maybe the mobo has a factury problem?
