Okay, I've been having some problems with my monitor.
At first, it was only when I tried to play a game called Team Fortress 2.
My monitor would go black and I would get the message "VGA: No Signal" like it says when the monitor is already on and I start up the computer, until the computer starts to boot.
Then it started to happen more frequently, when I was just surfing the web, or sometimes even just if I was sitting at the desktop.
Sometimes if I wiggled the video cord it would bring the picture back. Sometimes I could unplug and replug the video cable. Sometimes I had to restart the computer multiple times before I got my picture back. Sometimes, if I could bring up Windows 7's crtl+alt+del menu, I could get my picture back.

The other day my dad noticed that I had recently, by accident, plugged my video cable into the slot that connects to the onboard video card, instead of the newer video card I installed. I switched the video cable to the other video card input, and it seemed like the problem was fixed.

However, last night I got the message "VGA: No Signal" again. We unplugged the cord again and plugged it back in and it worked for the rest of the night.

This morning I tried playing a little Team Fortress 2, when I got "No Signal" again. I tried to quit the game (hard to do when you can't see it) and hit crtl+alt+del to try to bring up the menu. I tried it a few times, but couldn't get my picture back. So I shut down the computer and started it back up again.

But it didn't start back up. Instead I hear "beeeeeeep....beeeeeeep....beeeeeeeep" and then I shut it down again.


Anyone have any idea what's going on here?
