The M5020 motherboard/video chip is defective and it's a known defect in that particular Dell machine. The solder joints underneath the video card are not done well. They crack, dry up, etc.

The fix is a new/replacement motherboard.

People have also tried baking the MB in a home oven and letting the laptop overheat while wrapped in a blanket. While these "fixes" may work for a short time the problem will reappear.

I suggest you just move on to a newer laptop.
