Computer loses video signal

Dell Dimension 8300

Specs: XP Pro SP2, 3.0GHZ / 512 MB

Hello Guys,
I'm trying to fix this Dell. It has a NVidia GeForce FX5200 Video Card. Sometimes, during use, the monitor loses the video signal for a few seconds. It comes back after a few moments, but sometimes it just freezes (requiring the computer to be powered off). It has become more frequent lately.
The problem seems to happen when a lot of the video power is needed. For example, when I use Google Earth, the 3D rendering seems to trigger the problem.
I tried different monitors and the problem persists.
Any clue?

To start with, the FX5200 isn't a very good card & 512MB really isn't very much RAM these days.

As for your problem, it could be overheating or a driver issue.

If this is a desktop, failing power supplies are common and can cause your symptoms. E.g. a faulty PS can cause problems when there is more load on it.
Check your PS.

It seems the problem was the video card, I changed and the machine worked properly.
Thanks for all the info
