trouble with Gigabyte

hey jeg har lige købt dette system..

CPU: intel core 2 duo e6600
motherboard: GA-965P-DQ6
ram: OCZ Gold XTC / PC2-6400 / 2048MB (2x1024) 800 MHz.
GPU: ASUS 7950GX2
2*320 segate sata II disks
an one standard cd-drev.

hey i got a trouble with a gigabyte GA-965P-DQ6.. I have put it all together an every time i turn the pc on, there is no picture on my screen and i first change the GPU to 7600GS but it dident help.. what am i gonna do?

make sure the monitor works, try both monitor and gfx card on another pc,rare to be a motherboard issue they are so strictly tested before they leave the place

I heard the Gigabytes were fussy about RAM - needs to be 1.8v and wont boot with 2.0 or 2.2v??
