A week after downloading the new GeForce GT 540 drivers
I started getting a rippling effect rolling up my screen only while I play video game (COD2). It was the same day that my parents maid came and cleaned and she cleaned my laptop (Asus K53SV) and knocked it off dual monitor somehow. Could she have caused the effect too?
Anyway, my only thought was that it was the driver
so I rolled back to the old driver. When it came back, my windows frame and taskbar colors were much lighter colored and the Thumbnail previewer changed to a list. No problem, I switched back to the new driver (rippling effect never went away) and all was fine with Thumbnails.
Today (several days later), I started up the puter and the colors were lighter on Windows and the Tumbnails Previewer was gone. So I rolled back the driver and reinstalled new drivers and nothing changed. I googled the problem and found Brink's instructions to save Thumbnail Previewer thing to desktop and hit merge, etc. and restarted and still no Previewer.
