DFI Lanparty NFII Ultra B problem...
First things first, im an experianced computer builder so please dont suggest anything as simple as "check for short circuiting" and the like. Okay...
After pressing the power button on my computer (to turn it on. I was rather unamused when the *** at DFI support thought i ment when the computer was already turned on) it powers down 3 seconds later...
What I've attempted
Tried 2 different power supplies, no effect
Tired a different CPU still no effect
Tried different RAM no effect
Tried removing all IDE devices, still no effect
Tried removing all PCI and AGP cards, no effect
Tried resetting the CMOS no effect
Points to note
When CPU is removed the motherboard powers up properly
This is a replacement motherboard from my supplier since my last one failed on me for no reason so its total runtime is nill
There are no signs of physical damage to the motherboard.
There is no error beeping at all
Any ideas that i might try or check for would be great, excluding returning it.
