Are you sure you plugged in the power connector for your hdd, i was clearing my CMOS and i accidentally bumped it out, and my system wouldnt boot i was like WTF! and then i saw my power connector was out lol
does your mobo have any red LED's on it. and how many of them are there, cause for some reason my ultra-D has it. maybe minesi s a SLi-DR LOL and i dont even know shame on me, why i buy stuff that i dont know on ebay lol
If you really need help and you have a DFI board, head over to DFI-street.com. I had a problem with my RAM running in dual channel, and they were able to help me fix the problem.
It's your CPU. Trust me, something is not right with it. Look it up anyone, in any A+ manual, when the RED LED is on, and no other one is on, it means its a cpu problem. The cpu doesn't pass the bios cpu test.
