Solved Comp posts fine without any drives connected...

Tossed together a frankenputer with some parts laying around. Was working great today. Went out did some yard work, came back later and it won't start. It tries but won't post. If I unhook both HDD's and the CD it will post. Hooking any HDD up stops it from even posting.

Very odd. Any ideas?

Solved: Power supply

With the frankenputer, have you installed in of the mobo drivers from the mobo website? If that doesn't work...try a BIOS update. Follow your mobo instructions to the letter, otherwise you can brick the computer - make it a giant paper weight.
