Help with LCD screen on Dell Laptop? What to do? (With Video)

Ok, so here's how the story goes. I've had this pc for several months now(its probably a few years old since a hospital gave to me after saying the battery doesn't charge) and the message the nvidia kernel mode has recovered from a crash (or something very similar to that) has happened occasionally usually resulting in the pc going black for a few seconds then working again. this weekend a bunch of stuff went wrong, it gave me the blue screen of death about twice in one day. then the video driver (which is the same mentioned above) crashed about 4 times consecutively. it would do it at completely random times before hand . my question is, what do i do? it's no longer under warranty. One thing i noticed is that when i start it up i enter my password blindly since i cant see due to the screen not showing properly and boots up fine its just the display is screwed up somehow. Can anyone tell me how to fx this?
thxx!
