drop down windows does not work

[begatdj]

my screen saver suddently did not work, the pictures I was using did not show and my desktop shows all the time
in personalization/screen saver when I select a line in the drop down window it quickly goes back to the first line (none). the same happens with power management (my monitor is always on) , I cannot select a line from the drop down windows in services either (MS config).
I can force the selection of a line by holding the Ctrl key at the same time I select a line but when I click apply/OK it does not acknoledge my choice and goes back to the top.
what I have done so far to try to fix the problem (without success)

1. Update the driver for the mouse (device manager) ( it was up to date), and change USB port for the mouse .
2. Did a windows repair at startup (F8), everything was OK
3. Run in save mode an SCF/scannow, everything was OK
4. Uninstall program that were installed in the past 10 days
5. Did a System restore to the earliest date available
6. Run Ccleaner, Microsoft security essential, registry cleaner, Malwarebytes.
Nothing worked!
is there anybody with this problem who was able to fix it?

begatdj it happens to all of us. Some times we can't see the trees because of the forest.
