Blue Flash

[PGit]

I've been trying to assemble a PC, I decided to test it to see if it would boot up, periphials such as the hd and floppy were disconnected and I plugged it in. Switched on the socket and nothing happened. I tried the same with the ac switch on 230v and got a blue flash, then still nothing (including the power supply fan doesn't spin).

I fear that I may have blown the motherboard (though it was lifted of the case by the supplied spacers).

The video card, cpu and the ram were connected though, would these have been damaged.

I've tested the PSU by shorting the on pin to a ground pin and
it didn't work so it may be the psu that isn`t working and not the motherboard.

I may have to get a new motherboard anyway.
The one I brought off ebay (or thought i had) and the one I was sent are not the same, the seller sent an e-mail stating this nbut I presumed that it meant a different revision, no it's a completly different make with only 4x AGP (whereas the one I thought i was getting had 8x so my graphics card isn't compatible with it) and 333 DDr instead of 400.
