[Help] My system doesnt want to POST.

post #1 of 24
Thread Starter 
Last night i was busy doing a bit of cable management on my wall mount and it was getting late (11Pm to be precise) All of a sudden my light went off. Dad had turned of the power for my side of the house. Damn! My Pc wasn't on but it doesnt like the power being turned off at the plug or the mains. Coming home today I didn't think anything of it but as I turned my machine on it just stayed at 100% for all fans as it usually does when i turn it on. Now normally the GPU fan stays at 100% for 3 secs before dying down and it posts. But it just refused to. Things i noticed:
  • No HDD Activity Light
  • Power Button doesn't turn the machine off but it does turn it on
  • When I removed side, the CPU wasnt spinning
After noticing the CPU fan wasn't spinning I turned it all of and reatseated CPU and HSF; no luck. I am sure that the Motherboard isnt dead because the LED under the GPU still lights up, as does the LAN light in the Ethernet socket.

What could be the problem? Much help appreciated as it's christmas!
I Also reset the CMOS.

I had a similar problem once after moving my comp to university and I solved it by taking everything apart (power cables, gpus, fans) and building it back up again...

The Deconstructing idea sounds best, and if that fails I will give RMA a shot.
Thanks for your help guys. Anyone else have any ideas or help?

Bump!
An update, I disassembled the system and tried turning it on outside of my case in case of a short. No luck. even with a spare psu. The CPU Fan starts spinning for 2 secs then dies down. I think my CPU may be dead?
The fan works if i plug the 3 pin header into Chassis_fan or PWR_fan but still no post. I removed the CPU HSF and the Chip took 5 minutes to even get slightly hot.
What should I do?
RMA Board/CPU?
