I just built this PC a few weeks ago...I first hooked it to my monitor with the DVI but it had a strange line down the left side...so I switched to VGA and that solved it. I hooked it up via DVI again after I had everything installed everything and have been using it for a couple of weeks and now I get no signal...what could be the problem? Is there a setting somewhere that may need changed? In the BIOS maybe? I would assume it's just my monitor but was just looking for ideas...
