I bought a brand new computer a few days ago. And now i have put it together.
But when i connect my monitor (BENQ G2420HDBL 24" WIDE LED BLACK) to the PC it just comes up "No signal detected" and then it goes into stand by mode. I use a DVI cable.

Same problem (and same monitor) here, but mine works with a VGA cable... So it might be a monitor/cable problem... Does the card have any kind of analog output?
You haven't mentioned... does your MB beep at POST to let you know it's found a GPU? Or do you get error beeps? There should be an explanation of beeps in the manual.
