Dim Desktop problem on Acer Aspire One D270

THE PROBLEM

The problem with my AOD270 is when you try to install or start a program, on which Windows 7 reacts as a potentially unsafe - dims screen, you get a black screen! You can notice the backlight shining, but there is nothing on the screen. The computer works, but the screen not!

The only thing I could do is to close the lid, to make it sleep. After that open and wake it, then the screen is OK.


SOLUTION !?

No good solution for now, only a workaround. Go to Control Panel / User Accounts / User Accounts
and press "Change user Account Control Settings":


You have to switch to the less secure option with "do not dim my desktop".

My proposals are that this problem is related to one of the following,
1. Bad drivers, video chipset
2. Bad BIOS
3. May be worng Windows 7 power profile.

Please share some ideas or solutions in the comments below
Thanks
