Foxcon M61PMV won't boot

[Mr_Sukebe]

I'm hoping that someone might have some useful suggestions.

I have an XP system with an Athlon X2 4400, Foxcon M61PMV AM2+ motherboard, 2GB of OCZ ram, BFG 7950 in a Silentium case.
Until yesterday, worked fine (if nothing like leading edge).

Either way, I put it into sleep mode last night, woke up this morning and it wouldn't come out of sleep mode. I rebooted the unit and have got zilch.
On powering up, all of the fans spin up (CPU, graphics card and case), the network card lights up and the hard drive spins. Nothing is being sent from the graphics card. I've tried the following, none of which work:
- Giving everything a good hoovering to clear dust
- Installing a spare graphics card
- Clearing the CMOS
- Unplugging the keyboard. That normal results in most motherboards giving out some noisy error message during boot up. Nothing.
- Took the heatsink off CPU. The heatsink was stone cold. I'd expect it to be warmer than that if say the system was actually powering up and the graphics side alone was ill.

That suggests to me that the BIOS has failed.
Any other tests you'd recommend?

The good news is that the motherboard is well under 1 year old, so if there's no other ideas, hopefully OCUK can help.

No ideas chaps?

Quick update for those interested. I wrote to Foxcon over the weekend and got a suggestion to try.
The recommendation was to unplug the ram, reboot, plug the ram in again then see what happens.
The good news was that after plugging the ram in, I actually got a BIOS screen up. Problem was that the next time I rebooted I was back to a blank screen.

Not that I'm complaining as that seems to confirm that there's no issues with the CPU, RAM or graphics card.
My guess is that using the sleep mode has triggered something in the BIOS that's buggering everything up. At least it's narrowed down the issue. Just awaiting a further response from Foxcon to see if they have any further recommendations.

We seem to be in business.
I tried again Foxcon's suggestion of removing the RAM, powering up, then replacing the ram, but this time also including a CMOS reset.
Initially that resulted in the PC stopping with a CMOS checksum error.

A few mins of googling and I tracked that issue down to the fact that the CPU can be overclocked and the motherboard couldn't decided what settings to use. Gave it a fixed setting of 200x11 and we're in business.

So I'd like to finish by thanking firstly Foxcon, who were far more helpful than I expected, and also OCUK, who wrote to me today offering to collect and replace. What a bunch of stars both of your companies are.
