A8N32-SLI Deluxe no POST

[Linflas]

I had the machine on this morning and was in another room. When I walked by my computer room I heard the UPS alarm going and found the macbine powered off. I turned off the UPS and turned it back on and it came on normally. When I tried to power on the computer the power light flashes and the fans all come on but then it all immediately shuts off. After further troubleshooting I have found that if I power it on without the 12V ATX power connected to the board it will at least stay on enough to run the fans but no POST or anything else. I then tried another power supply but the same result. If I power on without the CPU installed the fans all stay on as well so am I correct in suspecting that the CPU has died?

Edit: I tried the no CPU idea after my initial post hence the edit

It might seem weird to recommend that (perhaps it's too obvious and you have done that already) but... did you try to reset the CMOS...?

I actually had not done that yet but figured it was worth a shot but it didn't change anything. Right now I get the standard green LED light when the power supply is connected and powered on, and the fans will stay powered on with either the CPU removed or the 12 Volt ATX power connector unplugged which, according to some research, is power for the CPU so I guess at this point I am leaning towards replacing the CPU since 939 CPU's have gotten pretty inexpensive.

I would try that CPU on another MB - maybe the problem is the MB Power Supply or some of the capacitors.

I wish I could do that but this is the only socket 939 system I have and I don't know anyone else close by with one. Unfortunately everything at work is Intel based so that is not an option either. I may check with one of the local shops to see if they can pop it in a board and test it but that is really my only realistic option other than rolling the dice and going with the CPU as the culprit. I looked pretty closely at the MB and don't see anything that looks obviously toasted.
