PC won't post

Hey all,

Shut down my PC after a session on WoW the other night, only to wake up and it not boot.

Here is what happens, I turn it on and the lights and fans start but nothing else, no HDD activity or display to the monitor.

So far I have:

Re-seated and basically rebuilt the thing twice

Tried another GFX card

Tried other RAM

Took out any unnecessary hardware to keep things to a minimum

Took out any extra connectors (thought the 4 pin CPU connector might be at fault- but no luck!)

Seems like a CPU problem to me, it does run hot but never had a problem with it after 3 years of high usage.

Also, I mislaid my BIOS speaker when building

Anything obvious that I have missed?

Thanks for all the advice. I forgot to add that clearing the CMOS was the first thing I did

Either way I have ordered a new PSU:

My logic was that even if it isn't the problem I'll need it for my new build I have planned when my student loan comes through!

Will update when It arrives on Friday

Sounds like a motherboad issue to me- CPUs are very hard to kill!

Indeed, I've put mine through hell and back and it's always been fine. Just hope it's not a mobo issue :/

Seems it was the PSU after all! Whacked the new PSU in and worked without a problem.

OCZ StealthXStream 600w - But I've had it for over 3 years without a problem, which to me isn't bad considering I had about a year of 24/7 always on.

Not sure if I regret getting the PSU now - I'm not too great with knowing the ins and outs of a PSU but from what I've read you don't want it under volting? Running at 11.5-11.6 idle/load on 12v rail, and 4.9 on the 5v rail. Considering this is new and from a reputable company would I be entitled to RMA or will I just have to stick with it? Or is it completely fine?
