Post Dammit!!!

System Specs:
AMD 64 3500 Newcastle
Gigabyte 939Ultra
1gb Corsair XMS
Gainward 6800GT
Enermax 600Watt PSU
Scythe Kamikobo CPU cooler.
XP Pro SP2

The other day I set the above machine off, just downloading some stuff and it ended up staying on for a couple of days. About 3 days in, I came home from work and the machine had turned itself off. Odd I thought, so I booted it up again, all the fans came on, but the machine switched off before the GPU post screen came up.
Thinking the graphics card had died, I swapped it for a 6600, but to no avail.
I then took the cooler off, cleaned the gunk off, and fitted a standard AMD cooler, same thing. Turn on, the fans fire up but before the screen comes out of stand-by, the machine stops.

Just so Ive got things straight, the post order should be graphics---->CPU---->memory----> drives etc?

Any thoughts would be appreciated.....Im begining to think the CPU has failed in some way.......but surely the GPU would still initially post....no?

Are youe getting and bleeps?

As nvening says, listen for beeps (you may have to plug speakers into your audio out if your case does not have a speaker that is plugged into the motherboard in order to hear any voice messages/beeps).

Also, check the LEDs on your motherboard as it is booting up and refer to the motherboard manual for what the colour combinations mean.

One other simple test you can do is see if the Num Lock light on your keyboard ever comes on or if all the keyboard lights briefly flash on simultaneously during the post (the latter may be motherboard dependent). That usually indicates the motherboard and CPU are okay.

Theres no beeps at all, I'll check the LED status lights (forgot about those) although the machine powers off quite quickly, so I might not get chance.

Should have said earlier, but Ive laready tried re-setting the cmos.

Are all the power connectors for the board plugged in? Is there a +12V connection on that board? Also if you get no beeps, take the RAM and graphics out then see what happens - fingers crossed it'll complain at a lack of them.

OK, so last night I removed the CPU and RAM. Im getting to exactly the same point in the post ie. about 4 seconds in, the machine just shuts down. No beeps, no LED's no nothing.

BIOS error maybe?

[Wilier]

Well, I can only say that Ebuyer have far out stripped all my expectations.
I requested an RMA the other day.

I sent the board back yesterday, and a new one will arrive at my door-step tomorrow (Sat delivery ).

No explanation as to the fault, just that its broken.
