Possible NVIDIA GeForce 8400 Problem (or not?)

Hi all!

My laptop is a HP Pavillion dv6799 ep special edition with Windows Vista Home Premium. Recently, games which need only medium hardware configuration as well as the regular DVD and WMP video playbacks suffered the following problem:

Games: Alien vs. Predator always ran well (even a month ago). Now when the game starts (after the intro etc) the screen no longer refreshes, all the movements and ligts and colors stick to the screen as if one poured cans of oil paints on a canvas one after the other. Changing screen resolution, detail levels etc does not help.

The "Strategy 3: The Dark Legions" game (which is a recommended must for any gamers) now always quits in battle scenes. Previously I did not experience this very annoying problem. Both games I re-installed but the problems stay.

The DVD player now dies with a white screen frozen but still allows making backups of DVDs. Playback of such DVDs and avi movies result in that every 5 min the image freezes (the movie stops) but the sound still goes on. Then I have to exit/enter full screen to restore the film.

No components shows error in the hardware and driver manager utilities. I updated the graphic driver from the NVIDIA webpage, but no help. I did the same from the HP customer service webpage, but still no help.
The notebook otherwise runs normally, I do not experience other types of anomalies. It was not connected to the internet in the last two weeks (probs started a week ago). Antivirus/antispyware softwares such as AVG, Avast, Ad-Aware find no detectable item to report. I did not alter anything in the cofiguration, did not add or remove components. I did not do registry cleaning and so on.

I wonder what else can be wrong, or if is it a graphic card/driver-related error... Also, why something goes wrong in Windows if it is untouched (naive question)...
Any help is appreciated

Joeten, I registered at their webpage and downloaded the memtest programme for Windows. However, when iniciating the programme, my Vista reported that It´s not possible to perform the requested action because a component called cudart.dll is missing. The programme needs to close etc...
