VGN-FE21M Nvidia go 7600 problem

[Powertrip]

Hi all, I recently bought a Vaio FE21M. While I was testing it with some games (to get to know with its display adapter) I encountered a problem. Games look great but they all have the same strange problem when I move into a stage. It looks like those cameras on tv that picture lower refresh rate monitors (a horizontal line goes up or down at a fixed rate), but less intense and not at a fixed rate. It is like someone slashes my screen with a knife. I upgraded to the latest drivers that I found (v8.5.1.3) and I tried many differend options at nvidia's control panel. Could anyone help me?

I am no expert when it comes to graphics cards.
Have you tried any of the nVidia Forceware drivers from TweaksRus.com ?

If that doesnt work then...i dunno, might be worth sending it off as its under warranty.

I tried the site you proposed me and I found one more (Laptopvideo2go.com). I found the optimal drivers for go 7600 and now games play fullscreen in my widescreen, but the problem with the slashes still remains.
