A couple of years ago I built my parents a simple desktop for email and web. One of my friends had an extra video card laying around that I threw in because why not. Recently I got a call from them that one of the fans was making a strained noise. I should have told them to discontinue use, because a short while later I got a call saying it wouldn't boot. When the power button is pressed, the machine gives all the signs of booting - lights come on, both fans on the motherboard and the video card start running (turns out it's the video card fan that was making the noise - it's still strained). However, no signal is sent to the monitor. Things I've done: Made sure all connections inside are secure Removed the video card and attached VGA cable to motherboard output. Confirmed that the cable and monitor work properly Checked the motherboard for signs of being fried (burn marks, damaged capacitors). I didn't find any obvious damage. Here things go beyond my experience and I could really use help. Is there anything obvious I'm missing?
