No video signal for a VGA monitor


New Member
Hello all,
I'm trying to troubleshoot a co-worker's computer, but I've run into a problem right off the bat. No video signal. I've plugged the same monitor into my computer, which is using another VGA monitor, and it works just fine.

The co-worker's computer has a DVI connection as well. If the person who owns this computer is using a DVI connection, will it disable the VGA port? That would explain why the monitor is instantly going to sleep. I'm just wondering. For now, I can't do a darn thing on it until I can see what's on the monitor.
