At times when I do a cold boot (AKA hard boot) my video card is not seen. I have to reboot several times and finally it finds it again. It is not the video card. I have tried a couple other cards and the same thing happens. None of the cards have a problem in another system. The card used right now is a Sapphire 6850. A Gigabyte 560, a Asus 5770 and an EVGA 680 have all had the same problem on this motherboard. Put them in other systems and all is okay. I have tried a different PSU too. I have eliminated everything but the motherboard.
What might it be? It has a 3570K processor and 8 Gig of Corsair RAM. I have had the BIOS reset on me, but that has not happened since I reset the battery and later replaced it.
Forgot to add, the BIOS is F18. Only had this board 19 days.
