A weird, bad problem

I've had a system problem for years that sometimes my PC gets in a state where the video signal shuts down, the monitor light goes from green to blinking orange with the screen black.

It needes to have the power turned off an on to get a picture back. It lasts for a period of time and then goes off - it's like a power off - again.

This was a more rare intermittent problem, after the system was on for days (I leave it on all the time).

But not it's to the oint it's repeatable, as soon as I reboot the computer (no power cycle neeeded) it's fine until I start a breowser - I tested with IE and Firefox - and then as soon as the browser comes up, the signal goes. Then when I power cycle he monitor the picture is there for a few seconds and then it powers off. As I type this, the screen is off because it's a hassle to power cycle for every word or two typing.

The funny thing is, I don't think it's a monitor problem, at least no entirely, because if the computer is just running without a browser, it doesn't happen, I play world of warcraft and it doesn't happen then. There's some weird connection between any browser being up - it seems to start a lot when a new s browser window opens - and the monitor and video card.

This is an old computer, an AMD 2x00+ CPU, a 7600 GS video card, with a Sony 24" CRT, on Win XP Pro.

Given that the hardward basically woks in some programs, it doesn't seem liike just bad hardware.

Any ideas?

Edit: oddly enough, it was happening every few seconds when posting that; I went to hotmail and it stopped. The problem has now stopped, even after coming to this post.

I don't have Linux or really want ot get into it - but an update.

The video card stopped working (covered in dust with a broken fan, guess it's expected).

I replaced the nvidia 7600GS with an ATI 4650 ($110, love AGP prices) and the same problem has happened.

When I changed the screen resolution to a middle resolution between low (like 600x800) and high (like 1920x1280), to something like 1440x900, poof screen goes off.

Sometimes opening a browser window, screen goes off.

Otherwise the screen works fine all day. It definitely doesn't look like a random screen turning off activity, but something linked to the information/resolution.

(On another note, the Sony FW900 can do 2304x1440, but Windows doesn't have a slider choice aboce 1920.)
