Blank Screen

By invicta1100 ·
I have an XP SP2 PC that has started blanking the screen after about 20 minutes of operation.
It will not turn on by pressing any key, or moving or clicking the mouse.
The only way to restore it is to turn the PC off, then on again, at which point, it will repeat the same problem about 20 minutes later.
Anyone have a solution to this?

Disable the power policy that is screwing this up.

That was the first thing I tried. Monitor always on, no hibernate, no screensaver, etc.
Nothing changed. If the mouse isn't moved for a few minutes, the screen blanks, and can't be restored without shutting off the power and restarting.

Check BIOS power save measures

by Mayhem1969 In reply to Blank Screen

It sounds like you've done everything in XP to prevent this, but sometimes the bios will have power save requirements of its own. Check to make sure those are disabled as well.

If all the above is OK

Have you tried a different monitor?

These do fail and can be a Heat Sensitive Problem and if that is the case you will spend ages messing around with Settings in XP to no effect.

Try a different monitor and see if the problem persists.

Different Monitor

by invicta1100 In reply to If all the above is OK

I tried an older monitor but had the same result. In desperation I loaded the "fail safe" bios setting and got the PC to actually run for an hour, during which I ran AVG spyware and virus scans which were negative.
Then I tried to restart and now the monitor won't even start during the boot process.
What next?

Video card

by Mayhem1969 In reply to Different Monitor

You might have a bad video card, if your not even getting into the BIOS screen. You might also need to reinstall the driver for that card if it became corrupted.

Start with with the video card

by OH Smeg Moderator In reply to Different Monitor

Make sure that it is properly installed with any Power Connectors connected. This is important as if there is a Power Connector on the Video Card that isn't plugged in it will not be getting enough power to run properly. The M'Board through the Slot for the Video Card can not supply enough power to run modern Video Cards.

Also check for a buildup of dust & other rubbish on the Video Cards Heat Sink. If there is a fan there make sure that it's working as well. If it isn't there can be a major power draw that is stopping the unit working and it will be overheating and shutting down as well.

If you can list the hardware that you have installed it would help.

Oh if you have On Board Video make sure that you have enough RAM set aside to run it properly.

Video Solved

by invicta1100 In reply to Start with with the video ...

I went to MSI and found they had an upgrade for the K7T Pro2 motherboard to add AGP, etc.
After that was installed, the SIS card works perfectly. Thanks for the help.
