hi,

 

i have some problems with the Card Video ATI Radeon HD 4850 512MB for my imac late 2009.

this problems arrive when i see a video on firefox ( i didn't test in other browsers or application), my mac stop work and i have to restart it only with the back key off. i can start my mac only in safe mode. in this mode a lot of drivers don't start the process.

I'm sure there is something wrong on the card video drivers, the lcd goes fine (no line or something else).

 

what can i do? can i reinstall the driver? i can't find in site...

 

when i reistore my backup of three month ago all return ok. maybe it's an update of flash player?

 

please help me to fix this problem.

 

thank you,

best,

Lorenzo
