LanpartyUT 250GB - Stopped POSTing

[Kinsy]

As posted on DFI-Street; really want to get this fixed asap so i can get on with clocking :-

Had this board since yesterday, one of the lucky few in the UK that got one.

I was happily going at 255mhz FSB with the 9/14 modded BIOS for 4v vdimm (was using 3.2v fine). Had installed windows fine at stock speeds. After a reboot it shut down and wouldnt come back on again. The fans rotate for 2-3 rotations before going back off again.

I can only get it to switch on if i unplug the 4pin connector. The fans then stay on but the board still refuses to POST.

Have tried:-
- 12-hour CMOS clear
- 256mb Corsair XMS3500 or 512 OCZ 3700EB in it.
- Booting without memory fitted
- TNT2 or Geforce4 in it.
- Booting without GFX fitted
- Removed HSF and chip then reseated.
- 300W generic PSU
- Outside of case and inside case

Specs:-

3000+ Claw CG 512k cache
Thermalright SB-2 w/92mm YSTech plugged into 3-4pin convertor.
256 XMS3500 or 512 OCZ 3700EB
