PC video driver/software keeps crapping out.

One of my customers has Packard Bell Desktop PC. Every now and then, the video drivers seem to become corrupted or stop working for some reason.

About a year ago, I was first called out to resolve this problem. I uninstalled the video software and drivers, and reinstalled them. A few months later, same thing hasppened. This time, to cover my bases, completeley reformated/reinstalled windows etc.

The problem has just happened again and Im all out of ideas.
