Pretty basic setup, I've upgraded it to 2 gigs of RAM, and added a 8800 GT OC video card in the past year. Here's my problem: 2 days ago, I booted up my PC, and there was no image. I could hear the Windows start up noises, so I knew the PC was working, but something was wrong with the video card. So I opened it up, everything looked okay. I booted it up again and listened for any noises. When it starts up, I hear a few 'clicks', along with the video card fan whirring up. The clicking stops after a few seconds, the fan keeps going, and no image. So I switched to onboard graphics to see if I could find a solution. At first I figured my video card was busted, but then I tried a different video card I had lying around, and that didn't work either. So it must be the slot itself?
Also, a friend of mine recently installed a new ethernet card in my PC, I'm wondering if that's drawing away power from the video card? It's worked fine for a couple of weeks though.
Can I get some help? Any thoughts would be appreciated.
