Hi,
I'm using an AOC Spectrum 9klr CRT monitor and Windows XP.
In the last few weeks my monitor has begun having some problems, and there doesn't seem to be a pattern as to which programs are open when it occurs.
I'll be using the computer, sometimes it will not have been running for long, sometimes for hours, then everything on the screen except the mouse movement freezes, the whole screen switches to black, comes back with some scrambled lines and colours, then returns to Windows. After this has happened video files will play their audio but not their visuals untill I restart the computer.
I thought it might have been a problem with my video card, but I've left the computer running with an old monitor for a week straight and the problem didn't occur.
Any clues would be appreciated!

Try to connect your monitor to another computer to identify whether it is your video card or your monitor which is at fault..

But the computer ran without incident with an older monitor for a week. Wouldn't that mean it's more likely the current monitor causing the problem rather than the video card?

Yes, it's likely that the monitor is the issue (because of the older monitor not screwing up). But a test on another system will help to confirm this (and help to rule out any "quirks" that may have caused this).

Hadn't thought of that. The VGA cable is the one that plugs into the computer? I didn't know they're removable. I just took a look at the cable and it doesn't look too easy to remove. Is it a bit of work?

Thanks for the suggestions, I'll try the monitor on another system tomorrow.

OK I'll wait for the result of that test and we take it from there.

So I ran the monitor on another system yesterday and it went well. Plugged it back into my computer and and after a day it did the same thing.
I'm back to thinking it's the video card with the problem. What's the best way to uninstall all traces of the previous drivers and update them?

Step 1 Download latest drivers for your video-card do not install
Step 2 Remove allready installed drivers frm your computer and install the latest drivers
Step 3 Go to : Right click My computer Properties Hardware and remove the videocard via Rightclick
Step 4 : Reboot, the video card will be tracked ( assuming you have winxp) and installed via wizzard hardware and try again.
