It seems that everything is working when i turn on the computer. CPU fans works, 2 top fans work, rear fans works, front fan works. LEDs are on, on the mobo. graphix card fan working. HD is spinning. Tried only installing one stick of ram at a time. I'm pretty sure everything is connected correctly. Followed all the instructions

I think for now, OS guna use linux.

I haven't tried to install any drivers or BIOS yet, because the screen hasn't shown anything yet.

ANY help would be greatly appreciated.

THANKS

Can you verify that the Monitor works and/or the cable works? Do you get any beeps from the motherboard when you boot it up? Have you tried using both DVI ports on the GPU? Is the GPU fully seated in the PCIE slot?
