My P4C800 refuses to boot. I have tried clearing the CMOS but with out luck. I do not know whats wrong but when starting up my computer, I do not get even as much as a beep. The last thing I did before the problems arose was configure the automatic CPU overclocker at 20%. It could handle it so I set it to 30% and restarted but after that, nothing. What could be the problem?
 
The auto settings were not enough?

1.Try getting down to the basics, CPU, single stick of ram and the GFX.
2.Then try the other stick of ram.

If thats a no go.. Discharge the PSU (unplug it from the wall and hold the power button in on the rig for ~20 sec.) then unplug everything and pull the cmos battery. Give it 20min+ then try 1. again.

Check out all capasitors (bulging and or leaking) and fets (usually gets a knick in them) on the mobo and peek in the PSU, for possible damage while you have things appart.
 
I already disconnected the optical drives and hard drive, and tried clearing the CMOS, but no luck. I will try discharging the rig next.

The symptoms are that there is no CPU dectected. Is it a possiblity that the CPU was fried?
 
I can't take the CPU out but need this fixed. When powering up the CPU fan sounds like a turbine, indicating the CPU is still alive, and running at 130%. CMOS wont clear, or it makes no difference. Can't find anything on the internet about it.
 
Pulled the system apart; no processor = no errors. Only RAM, no errors. No RAM and the processor inserted = no errors.
 
how do you know that the fan is running 130%? and you connected the speaker right?...(sorry, had to ask)

anyways, thats weird, the Bios might be corrupted...

You should be getting at least a few beeps out of it....when you pulled it apart..

try this...with everything gone, can you get into the bios? and double check the jumpers, put them all to default position

And funny how thats the same mb that i rma'd, and it still doesn't work! I think its lifespan has ended...
 
Speaker is connected; Processor was set to 30% OC on the board's settings. I think the speaker may be malfuctioning, it should have beeped atleast once. Can't even get into the BIOS, the damn thing won't even POST.
