Dead component search.

post #1 of 3
Thread Starter 
Hello. My HTPC died yesterday, so I figured to look for help, since this is first time I faced something like that.

Basically while I was playing Blacklight Retribution, my PC suddenly turned off. I tried to turn it on/check connections, but I got nothing. When I turn it on the fans just turn on for a second, then the whole thing goes dead again. I figured that it might be a short circuit somewhere. I checked the whole thing, and found nothing. I isolated the motherboard with only CPU and 1 plank of RAM intact and got nothing again. I replaced my PSU with a 650W one just in case (had faulty PSU problem before). I cleaned my mobo from dust, and apparently it still doesnt work. I dont think its CPU because fans would still be running even without CPU.

The components are:

500W Kingwin Striker
Asus P5K-Deluxe
4 Gigs of RAM
BFG GeForce 8800 GTS OC
Intel Q6600 (overclocked to 3 GHz)

My questions are:

How can be 100% sure that its my mobo? I really wish it wasnt because there are no similar mobos on the market anymore.

What else I can do myself to avoid buying a new one?

Can I do the oven trick?

EDIT: I tried running the motherboard without CPU. The fans were working fine. Hope it means anything to you.

Reset the BIOS, then disconnect the PSU and remove the battery... leave for 24 hours and replace the battery.

If that does nothing useful, then I guess it's dead... always power down fully when "messing" with a problematical system.

All IMHO.

I was going to say power supply, until I kept reading.

Are you 100% certain the second power supply you used is working? If you are, then it sounds like the board is dead. Even with a failed CPU you should still see/hear a POST.
