So recently I decided that my old compy needed some updating. I get all the parts needed and get everything setup and.... the motherboard won't start. At all. The led backlights came on but nothing else happened, no bios beeps, just a whole lot of nothing. I'm beginning to think that it might be a case of it being DOA. There doesn't seem to be anything wrong but it's just not working.
I've tried everything possible right down to doing a test with the motherboard outside the case with only the 8-pin 12V and the 24-pin connector but nothing works.

One person on the ASRock forum suggested moving the jumper for the clear CMOS except that this motherboard doesn't seem to have that. It's got two clear CMOS buttons but not what they are talking about.
