I'm building a workstation for a mate. Asus P5AD2-E Premium mobo After the build the machine will power up ok but no picture. Voice error message says . "System can not start due to cpu overclocking" and "No VGA detected" So I clear the CMOS and the cpu overclocking warning goes away but I still get the no VGA detected message and no display. The fan on the quadro is spinning and I'm using a normal vga monitor with a dvi to vga adaptor ( the quadro has two and I've tried both). I suspect the quadro is bust but I think I'll buy a cheapo PCI-E graphics card by way of comparisson that way at least I'll know the mobo is fine. Any other suggestions?
