Well it's just the most horrifying thing I've ever encountered really...I bought this Dell Optiplex computer off of ebay and tried plugging a monitor into it today. The PC wasn't even plugged into the wall and as soon as I connected the monitor to the computer via that serial cable dealy, the monitor's green power-on indicator light turned yellow!

Has anyone heard of such a thing? My roomate says it is the video card, I just WANT to get an idea before I take it to my local repair shop.

I love ebay, but some people are just REAL scam artists, you know? Frig.

Thanks everyone!

BrentIt's not the computer.
If you power up most newer monitors connected to nothing the green light comes on and then turns yellow after no SIGNAL is found...the delay depends on the monitor manuf,I appreciate the reply, but it sounds like you're saying that it's the monitor, which it is not. See, i left it plugged in with both the PC and monitor's power supply also plugged in while I made dinner (approx 30mins) and it was still blank when I came back. Also, it's the monitor I'm using now that I tried which is new and works perfectly. you have VERIFIED that your monitor works by plugging it into a known working computer? if so, then i suspect the video card. I didn't say it was the monitor...i said this is normal behaviour for a monitor that is not connected properly or not recieving a proper signal...

Swap your vidcard into another machine to test this...if it does the same thing then as Homer says you need a new vid card.
