I'm working on an AMD 4000+ in an EVGA NF41 motherboard, with Corsair Value Select DDR400 ram. Today, I shut off the computer after doing some rather extended maintenance, big CCleaner, uninstall AVG to install Microsoft Security Essentials, etc.
The computer never came back.
The board turns on and then off immediately.
Things I've tried.
Took out the CPU, double checked it. Reseated it with new thermal compound.
Took the motherboard out of the case.
Tried another PSU, same behavior.
Did some pretty extensive compressed air work.
Took the battery out and left it out for 5-10minutes.
Reset bios by shorting the Bios reset pins.
Motherboard has a boot button on its very self. I've used this, as well as my cases power button, and then just shorting the appropriate pins with a screw. All produce the same behavior.
Right now, I sometimes can make it stay on with just the CPU in it. Sometimes not. I've got it sitting out of the case on a wood surface. A debug LCD display reads "C1" if and when it decides to stay on. However, if I remove the ATX12V 4 pin from the motherboard, it always boots and holds at FF. (I wonder if I just left out the ATX12V connector and went from there....hmmm.)
Long story short, extremely erratic boot process. If I leave the ATX12 4pin out, it always boots to FF. If I keep it in, 80% of the time it will just turn on and then immediately off. The rest of the time, I can get to a C1 error which may or may not stay powered on, with a repeating beep. From EVGA this means, "C1, C3, and other Cx errors are usually related to memory or memory controller errors." But its not consistent.
Is the motherboard just kaput?
Any ideas would be greatly appreciated. I'm at a loss.
