Geforce gt555m driver problem ?

[Msamir]

Hello, I've having this problem now for over a week and its slowing my work flow, I have a lenovo laptop Idea pad Y570 with geforce gt555m, recently I've updated the drivers to the latest one unfortunately when I did so every time I try to purge a file in AutoCAD I always get the error that the display adapter has stopped working and had recovered and one time it gave me the BSOD so I tried rolling back to an older driver but still I have the same error every time, I've tried several drivers but no luck, any ideas what's going on here ?

Thanks in advance.
