dolphin freeze my drivers

[diegochiha]

yeah is something strange,any game that i boot run full speed but after a while it makes my pc freezes and a little window popup saying that mi graphic card drivers stop responding,and both emu and pc just freeze ,anyone know any solution or workarround?.
Oh and btw this happens not only with a specific game,it happens with all my games (i mean in dolphin) pc games are just fine
Edit: Specs on signature

nah,dont think so,i have a fresh windows 7 installation,(i`ve installed it about a week ago),all the new nvidia drivers also,somebody that have windows seven and an nvidia card should tell me if he/she got the same problem as me,and if it dont,well,say me wich drivers do he/she use
