Did you ever resolve this problem? I have the same computer with Windows 7 installed after purchase and the same problem. Mine has now progressed from a bar flickering at the bottom of the screen to full screen flickering. I did have a period of about 6-8 months when the bar flickering stopped. This occured during fall/winter/early spring so I thought the problem may be heat/humidity related. It was after it started back up that it progressed to the full screen flicker. When the laptop is connected to an outside monitor there is no flickering. Any suggestions would be appreciated.
I recently just installed Windows 7 on my wife's laptop. It previously had Vista 64 bit and now of course has the 7 64 bit version. Everything has gone pretty smooth. There were a handful of drivers that needed installed but otherwise smooth. The only thing that remains finicky is sometimes I get flashing at the bottom of the screen only, like only taskbar width. I had it stopped after installing the newest driver from Nvidia but then when I ran the benchmark test from Windows for its rating system purely out of curiosity it started again. Initially once every 2 seconds now about every ten, and sometimes longer pauses inbetween. Which leads me to believe that it may be to taxing of the video card and it just glitches out when taxed. Although it seems it is probably a setting on the card/resolution/refresh rate/driver that probably needs adjusted to get it out of this little spat since it never had a single issue when I used Vista. Any suggestions would be helpful. I may very well figure this out on my own but figured it couldn't hurt to post here for suggestions.
