Power Surge - System Won't Post

Built a system for my uncle. Everything was dandy. He said he had a power surge, and now the system won't post anything. Nothing on the screen, no beeping. I can't even eject the optical drive, so I am guessing it might be the PSU.

However, the system LED lights come on and the fans turn properly. Anyone have aclue WTF is wrong?

The motherboard is a Gigabyte K8NXP S754 Board and the PSU is an Antec True Power 380w.

Thanks...I need to have this fixed in a couple of weeks and the PSU/Mobo are both under warranty.
 
Sounds like you don't have access to the machine. I would try unhooking the ide cable to an optical drive and leave the power hooked up to see if the drive will eject. Didn't you have him using a good surger protector?
 
Well I built it for him and he took it it with him when he moved. He said he was using a good surge protector, but I guess it was weak.

I'll try reset the CMOS, although I don't think that will do anything. I do think either the motherboard is fried or the PSU is bad. He did tell me that from time to time this would happen and he'd need to wait a couple of hours. That sounds like overheating, but it's not as the CPU was brand new and worked fine and I was monitoring the temps.

Those boards are bad about this problem. Of the probably 18 - 20 times I have seen this, I disconnected all cables to the MOBO, switched the voltage on the PSU to 230 and then back to 115, reconnect power cables to MOBO (leave IDE, floppy, etc. disconnected) and tried it again. If it still did not Post, a MOBO replacement fixed it. Of all the cases, one of the 2 corrected the problem.
 
well the drives power up now but still no post...time to rma the mobo...i sure hope nothing happened to the cpu.

thanks for the tips
