Flickering Desktop Screen

#1
Hello everyone,

I noticed that every time I click on the scroll bar or a window tab in Mozilla Firefox, the desktop monitor LCD Screen flickers at a fast micro second "blink of an eye speed".

When I click on taskbar, start menu and the application windows in taskbar, the desktop monitor LCD Screen flickers at a fast micro second "blink of an eye speed".
This happens off and on not consistantly, but somewhat often.

I have a Hewlett Packard g7 Notebook PC; bought 04/03/2012
Windows 7 Home Premium 64 Bit Service Pack 1
AMD A6-3420M APU with Radeon(tm) HD Graphics 1.50 GHz
Quad Core Processor
I have a 500 GB Local (C Hard Drive (441 GB usable)
I have 295 GB out of 441 GB on Local (C Hard Drive
I have 6.00 GB System Memory Ram (5.48 Usable)

I tried to make sure all my drivers were updated. They are all updated.
What could be causing this glitch and can it be fixed somehow?
Thank you for your advice, input and suggestions.
