Windows Vista: Graphics card problems: dv6780se

[Sobeysboy]

Yesterday I was playing a game and it said "your graphics card is out of date", I just ignored it because my game was still running fine. Later I went to check and see if I could download an update and so I went to look for my graphics card in control panel. I found it I think. It's called Nvidia Phys X. The weird thing is it acts like it's not there or turned off. It says "no ageia phys X processor installed under info and under settings you can pick "no acceleration" or "Ge-force phys X" or "ageia phys X" I can only choose No acceleration I later went to try the game again and now it no longer works. Someone please help me

Have tried running DX Diagnostics; and under display this is what I got:

I know it's not the game; my "display devices (in Device Manager) is still MIA from my device manager and also it's multiple games that were working before then all of the sudden just stopped.

I have tried installing the latest NVidia drivers (then uninstalling/ reinstalling), to no avail.

Any ideas?
