off topic for this question. i started having strange post codes before the usual "C1", like "1C" "1U" and more often ".88.". i spoke with dfi tech support and was informed that this could be a corrupt bios or a bad power supply and ".88." is an LED segment check. i noticed these post codes after putting in a new corsair 850tx but the codes could have started happening before this new PSU. i tried a PSU from a different system, where the same LP would go to "C1" and no other post codes would show before the "C1". the PSU from the other system would allow my system to boot a normal "C1". so i put the corsair 850tx in the other system and had the same unusual post codes before the normal "C1". today i got a replacement antec PSU and am getting the same strange post codes before the "C1". ??? does it appear that i need to RMA the new power supplies, corsair and antec, can i fix this with a bios flash, or do i need to RMA my motherboard? thanks in advance.
