Hi guys, just got all my parts in the post but i cant get this baby to boot up! 
Its a abit Fatality mobo, 8800 gts, 2gb geil
It will hang on boot and do 1 long beep with 2 short beeps, I think that means theres a problem with the graphics?
Iv put the 24 pin power and the 6 pin on the mobo and iv put the power in the gfx (if you dont do that it sounds like a bomb is about to go off)
Tried with no ram and i get 1 long beep so its not that
The psu is a corsair 520w
Also theres another 4 pin connector on the mobo that says is for 'auxiliary power to pci devices' do i only use that if iv got 2 pci-e gfxs?
I really really really hope my gfx isnt just dead because now i dont have a pc
Thanks for your help
