hi i have an acer 5920g, with an nvidia 8600m with windows 7, a few weeks ago i was playing batifield 2 and my laptop crashed, upon restarting the laptop the screen had lines down the screen and would not start any games or complex images such as in i tunes with the artwork, i have used system restore, and updated he drivers, i have also payed for a brand new anti virus and completed a full scan, somtimes the laptop will restart in the most basic colour settings i have ever seen and this usually happens after i have reinstalled the latest drivers nd restarted the system, device manager comes up with error code 3 if that helps at all, i have no idea if the card itself is broken or if there is som ther underlying problem, but i would be very grateful for any mor ideas
