I could use any suggestions with a problem that just occurred last night.

I removed a hard drive that I no longer needed installed. After removing the hard drive, my system stalls at post code 25. Last night, a few power cycles and a few times I got into BIOS, but that has been it. I've been trying to get it to work all day today and it will not go past post code 25 at all.

I stripped everything out. No cards installed except video. No drives connected. I've reset CMOS, pulled the power cord and yanked the battery. I've tried an old PCI video card, different RAM sticks and another PSU.

Connecting the old hard drive didn't do anything. I don't have a spare CPU or mobo around to swap those. Could it be the CPU or most likely the mobo? Anybody know what the warranty period is on these mobos?

Thanks.
