Ok, here's how it started. I used to have a GeForce MX440, until it died a bitter death. I replaced it with a GeForce FX 5500 purchased at TigerDirect, thinking it was a better card. Here's what happens. With the MX440, I was able to play all kinds of games (Warcraft, CSI, Doom) with no problem. When I replaced the 440 with the 5500, I could still load Warcraft, but about 30 seconds into the game, the monitor would shut off. I would have to manually restart the computer to get it back up. So, I tried re-installing drivers for the video card and updating the motherboard drivers. I tried removing the card and putting it back in. Whenm that didn't work, I thought it may be windows related, so I uninstalled XP and formatted my drive and re-installed windows. That didn't work. The monitor kept turning black after about 10-30 seconds. I read that the onboard sound might be conflicting with the video card, so I disabled that. I disabled the onboard video thinking that that might be the problem. Nada, zilch, nothing. It's gotten so bad now that I can't even load XP (unless it's in Safe Mode) without the monitor shutting off. I'm assuming this is a video card issue, but I can't figure out what the issue actually is. I've searched and searched and I'm two steps way from taking it to a computer place to get looked at, but I wanted to see if I could get help on here first.
