Monitor Turns off

[xonic1]

I just started playing some Battlefield 2 again, I play it for anywhere from 1 minute to 20-30 minutes and my monitor will go blank, it doesnt power off completely. It almost seems like my video card may be overheating and it shuts off, because my pc stays on the whole time and i have to restart to get my monitor to come back on. At my old place, the house power kept going out a lot which i thought may have messed up the power supply somehow. Im pretty sure it is the video card, but i dont see why it should be overheating, i even opened my case and my room is not near hot enough to make it overheat because it works fine whenever I am not playing a video game. Are there any other possible problems? My computer was also freezing at the windows loading screen and it would reboot itself or just freeze, i fixed that by going back to service pack 1 and it works. Not sure if these 2 things are related at all. Thanks

The next time this happens you could try ctrl alt del and see if anything comes up, I think normally if you do that in BF2 it will minimize the game and give you the task manager, haven't tried it. Also I'm not sure if you normally can turn on and off your caps key when in game but you could try that, if you can't turn caps lock on or off then it's some kind hardware problem most likely. It could be your video card overheating.

Dunno if this will help or not, but my friend's Dell 19" LCD was doing that; the computer was still running fine but no monitor. She had to completely power off the monitor, wait a little while, then power it back on. Then it would only come on for a few seconds. She repeated that until she could properly shut down the computer, then she had to wait an hour or more to power back up. And the monitor would still go blank after being on from a few minutes to about an hour.

It got progressively worse, too. RMA'd the monitor three separate times and finally got one that worked....then THAT one started failing the same way. Dell's site had many similar complaints.

Since yours is a Viewsonic and not a Dell, may not be the same thing. But I would check the Viewsonic forums and see if anyone owning your model is having the same thing happen. Might be a monitor issue.
