"couldnt load open gl........"

everybody knows this fucking problem. there is the prob when the nvidia driver is too new. i have the version 77.72. but this version is too old for games like CS:S or watch fragmovies.

but its not the problem.the biggest problem of this fuck are the lags,when im looking ET or CS movies(only fragmovies or something recorded by myself.there is no problem when im watching normal movies). all 3 or 4 seconds WMP lags for 1 second and then its going on. im pissed off. i asked some dudes and they said me its because of the old version of my nvidia driver :<

how can i play ET and can play games like css or watch movies without probs with the same nvidia driver? :(((
