Windows 7: Some Menus and Windowed programs Flicker once a second

02 Dec 2016   #1

Windows 7 Ultimate x64
Some Menus and Windowed programs Flicker once a second

I have an old(about a year) problem with some menus and windowed programs flickering nearly once a second.
I have Searched for the solution but i couldn't find anyone having the same problem.
sometimes it flickers every 2 seconds or 3 seconds.
The period of flickering is a multiply of 1 second.
For example the Options menu in Chess Titan (windows7 game) flickers.
Texts ,Check Boxes and Control Bars flicker in that menu.
another example is the internet download manager that completely flickers always at 1Hz.
another example is windows notification menu at the bottom right corner of screen, it flickers.
another example is device manager menu. The texts of hierarchy menu flicker.
it seems like Programs and windows that are depend on dot-net framework have the problem.
But i found this problem in another application which was using windows GDI graphics and when i turned on OpenGL hardware acceleration on that application it didn't flicker anymore.
Whenever i restart the system, the flickering stops but it starts when i play some high graphic games or when i start windows update check and the flickering does not stop until i restart.
It was a long time that i didn't play any game and didn't do any windows update so i forgot the problem.
The flickering Maximum Rate is 1Hz and its rate increases mostly when CPU works harder and the system fan turns faster.
some menus and some texts flicker more recently and some others flicker rarely.

in my opinion the problem comes from windows and its belongings.
my graphic cards are up to date.
my last windows update was about 2 month ago but i have the problem for 9month.
i have re installed windows but it didn't work.

my CPU:
core-i7 4710MQ

my graphics card:
intel HD 4600
Nvidia Geforce 820M

Here is an example of menu flicker which i have taken its screenshot by print screen button.
its interesting that i was able to take its screenshot!!!
at the first picture IDM shows correctly but in the second picture which occurs every second and lasts for about 100 millisecond, the IDM window is completely blank!!!
