Nvidia GeForce 8600 M GT PROBLEM!

[sejfti]

Hi guys, i installed Windows 7 few days ago on my notebook, ACER ASPIRE 5920 G

Specs:
Intel Core 2 Duo processor 2.0 Ghz
2 gb DDR2
Nvidia GeForce 8600 M GT 512 mgb (up to 1028 mgb)

At first, I installed old drivers for Nvidia, they were working OK but they are for Vista, and I noticed in Performance Test that Graphics scored 3.8 which is much lower than I had before...

Than I visited ACER support, found Nvidia 8600 GT drivers for Acer Aspire 5920 g for WINDOWS 7... And installed it... My performance test on graphics now shows 4.8 and gaming graphics is 5.9 BUT...

THere is some kind of blinking on the screen.... some lines appear for a split of a second, every few mins (more less)

Hows possible that win 7 drivers are having problems with Win 7, and Vista drivers are ok with WIN 7????

Also, I reinstalled Vista drivers, there was no blinking or anything similar! ?

Can anyone help me please?
And, how much worse my graphic card will work with Vista drivers on WIN 7? Should I maybe leave it with old drivers?

P.S.
It doesnt blink when i play a movie or play a game...

Thanx!!!

update

Just to update on the situation...
Driver is not working at all... after blinking, whole screen got blurry and unusable! I had to reinstall old drivers, AKA VISTA DRIVERS!
