Problems about running screen savers.
Control panel > System > Hardware > Device Manager . See if the graphic card device has a yellow or red tag, right click on it and select ?update driver > browse computer for drivers? or get driver from disk, put in your old driver CD, This will most probably get your screensavers working.
Aquarium Screen saver problems?
Go Display > Themes > Aquarium, go to Screensaver ?Settings? , then at bottom of window is the ?display Settings?. That shows the monitor, and there might be a check mark in the box "Display Blank Screen" . uncheck this box to see if you have a fish tank that moves. If so problem solved.

WARNING!! Make a backup of your registry before you make any adjustments to the registry. Anything you do in the REGISTRY could make your computer unusable or unstable. WARNING!!
1.Click Start > Run, type regedit and hit [ENTER].
This will open the registry editor.
2) In the left-hand pane, click on the plus symbol - "+" - to the left of the HKEY_CURRENT_USER key (this is the "HKCU" referred to in the above quote).
Then look for Software and click the plus again, then Microsoft, etc, until you reach down to the following:
HKCU\Software\Microsoft\Windows\CurrentVersion\Media Center\Extensibility
Be certain that you are here and not in another part of the registry!
3) In the Application folder, locate the application...
Note the GUID associated with it.
4) In the Categories folder, look for the subfolder which references the GUID you found in the previous step.
Note the full name of this folder.
5) In the Entrypoint folder, look for the subfolder which bears the same name as the full name of the subfolder you found in the previous step.
Create a string value called "Enabled" with a value of "False".
6) Repeat the exact same process for the same add-in in the other key...
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Media Center\Extensibility
7) Having changed the setting for ONE ADD-IN, save the registry and reboot.
The screen saver does not work on XP MCE (Media Center Edition).
Turns out, ehtray.exe is the culprit. It's the part of Media Center that downloads the guide information. When it's
running, screensaver will not kick in. When you manually disable it via the
task manager, your screensaver(s) should work.
You can also disable it by running the ?msconfig/startup..untick ehtray?.
