Hello, i was recently given a "nspire" laptop from my father because it was giving him issues, its windows 7 and the problem with it is anytime your on it for any more than lets say 30 minutes it starts crashing going to a black screen, if u moved the mouse around frantically it will recover and a pop up will appear reading "intel display driver has stopped responding recovered" now i have narrowed it down to 2 things(i could be wrong) but either something is not installed properly, which really i dont know of a way to tell if thats the case, o over heating...i have a fan for it now and it helps but it still crashes, someone brought to my attention that it could be the resolution but when i go to change it in my control panal in advanced setting and troubleshoot tab it does not allow me can you please help me oout with this.
