Monitor blacks out

Its not you or your PC. if you read around, its clearly a monitor problem, a manufacturer monitor problem, since so many people are having the exact same problem.

I cant turn my computer off once my screen is working, in fear of me having to sit there for a good 5-60 mins turning off and on, and off and on the pc and monitor again after again to hope the next time the screen isnt just plain black.

Sounds like your video adapter settings have been wedged. If you are running Windows XP Service Pack 2, you can use the following steps.

1) Boot the laptop into safe mode. Boot into safe mode with networking support if possible. This can be done by tapping the F8 key as the computer first turns on.

2) Once you are at the Desktop, right click on My Computer and select Manage.

3) In the window that appears, select Device Manager from the menu on the left.

4) Find Display Adapters on the right and click the plus sign. This will list the video adapter that you have.

NOTE: WRITE this down EXACTLY. You may need to go and get drivers for this. Seeing this is an older model, I doubt you'll need it, but better to be safe then sorry.

5) Go to your manufacturers support web site and download these drivers. You may not need them, but better to be safe then sorry.

NOTE: Skip step 5 if you did not boot with network support or cannot get to the Internet. This can be done from normal mode.

6) Right click on the display adpater and choose un-install. Hit OK on the window that appears and reboot the machine when the process is done.

7) The machine will take longer than usual to boot, as Windows XP is re-discovering the video adapter and resetting everything to the defaults. When it is done booting, the screen may look weird since the settings are now the defaults. You can the set them to what you want by right clicking on the desktop and selecting properties. Then go to the settings tab.

8) IF it did not re-discover the video adapter (this can be confirmed through the device manager), then go ahead and install the drivers. Windows Update will most likely also have the drivers.

NOTE: This process should work with Windows 2000 as well, although I was not able to test it. The only issue I can think of is that it may not auto-discover the video adapter, and you would have to manually download and install the drivers.
