When the computer has been in use for a while, sometimes the screens (double screen setup) start to flash black screen iregularly.
Suspect that it starts when the computer gets warm or working with multible applications. But there is no regularity in when it happens.

Sometimes it stops after 5-10 flashes.
Other times it continues.
Sometimes it comes very fast after booting, and sometimes it doesn't come at all.

I can make it stop by turning of or putting the computer in stand by for a few minuttes.

What causes this problem?


NB: I have NOT installed new videocards, drivers or anything like this recently?
I did not know if this was a hardware or XP topic.

Check Event Viewer for related error messages?

Black screen failures in XP usually fall into one of two categories:
1) Hard drive issues
2) Video issues

For the Hard drive issues, you can try the following steps:
1) Run "chkdsk /f /r" (without the quotes) from the command prompt (if you can get into Windows)
2) If you can't get into Windows, you can use your installation CD to boot into the Recovery Console and run "chkdsk /f /r" from there
3) Use the Recovery Console to run "fixboot" and "fixmbr" (without the quotes)
4) Download and run a diagnostic utility from the manufacturer of your hard drive


For the video issues you can:
1) Uninstall your video drivers (and video driver software), then update your video drivers to the latest available version from the manufacturer of your video chipset (ATI, nVidia, Intel, etc)
2) Boot into Safe Mode to see if the problem occurs there - if not, then it's likely that the video driver is the problem.
3) Try another video card to see if the problem is with the card itself

Are you sure this isn't a monitor issue?

Suspect that it starts when the computer gets warm

The monitor is also warming up.

I have NOT installed new videocards, drivers or anything like this recently

Another clue that it could possibly be the monitor.

I would suggest trying a different monitor, or if you don't have another, switch the two monitors and see if the issue follows the monitor (assuming it only happens with one monitor).

sometimes the screens (double screen setup) start to flash black screen iregularly.

Well, if it always happens with both monitors, then it is probably not monitor related.
