Problems with my computer

[NeoGaddy]

ok i have a custom built ninja pc, wit a ABIT-NF8-V2 motherboard, the computer turns on, both of the fans do too, a couple of months ago i got a brand new desktop and i putted this 1 to the side for a bit and when i tried using it again the monitor stays black, when i disconnect the monitor a screen pops up saying testing monitor etc, which means the monitor is in good condition, but when i plug it back in everything goes back to black and im not sure about what my problem could be, hope to see some replies and thanks guys..........

It's most likely a fried video card, but I would try another monitor first to confirm.

Any Beeps

Does the PC make any beeps when you turn it on. Or does it simply turn on and the fan spins?
