Need Hlp With Video Card Troubles??

hi there umm i keep either crashing/freezing/lock up because of these 2 errors
either nv4_disp.dll or nv4_mini.sys can someone hlp me figure out what i can do to fix it thank you very much=)

Uhh, lets try starting with system specs and what you do that causes the problem.

check my profile...

What have you done already to fix the problem

Have you tried to uninstall/reinstall the display drivers?
when do you get the error.. when playing games, watching video's or when not involved in high graphic related apps.

Is your system overclocked?
