Ok since he does not really have access to internet at this time I decided to post on behalf of him. Here's what he has tried so far and all results in a no post: -Clear cmos with battery taken out and using the jumper -Minimal bare boot with 1 ram stick and no drives connected As an FYI, he does get all 3 green lights on his HD4870 for power ok. This happenned after he installed NB SB and Vregs for watercooling. I am thinking he has a short from one of the waterblocks to the motherboard. Any ideas? PS: He does not have a backup psu or video card to try and is unable to gain access to a replacement.
