System Failed CPU Test *HELP*

[Mafiaz]

Hey guys hopefully someone can help me figure this out.
My computer was working fine yesterday night, was cycling it on & off trying fans and then left it off and went to sleep.
This morning powered it on and nothing except for speakers saying "System Failed CPU Test".

Also strange is that the system powers it ON as soon as I turn on the psu from standby mode!
(I think I had the mobo turn off the system last, this morning the on button did nothing so tried the psu switch, moving it to off, and then switched it again and immediate power)

I tried switching psus, same problem. disconnected power to all ide devices, same, removed video card same. removed mobo batt and reset bios, same...

atx 12v is plugged in

full system specs

Asus K8V SE Deluxe
AMD 3200+ 64-bit 512L2
Ati radeon 9700 pro
512 3200 crucial
200gb hitachi
Quite a few fans

this is all on a 430watt antec True power

i believe that the key would be figuring out why the system starts automatically but then i don't know that much. thanks for help and bumps!

now it's just bare motherboard with cpu and fan connected to psu, when psu switched on still automatically starts system. no shorts or anything possible, speakers still say cpu failed

bump anyone have any suggestions before i rma it?

if possible... can you try and use the cpu on another mobo? perhaps a defective cpu?

What sorts of fans are we talking about here? If they're plugged into the motherboard, unplug them and see if it POSTs.

Yeah, check all fan connections. Remove and reseat your CPU (and check the pins and socket for damage). Make sure the HSF isn't on backwards (not sure if that's an issue with s754).

Hopefully thats not an OEM CPU....
