Help with stopping rundll32.exe process

My buddy has a laptop that was infected with a virus. Virus is longer on the laptop.

However after about 30 min or so, sometimes a little longer it BSOD's on him.

We did run process explorer and noticed rundll32.exe trying to run a file that no longer exists... Question is; how do you remove a rundll32.exe process from running?

Registry is clean from any trace of this thing.

Here is the screen shot of the file in question.

reinstall his gpu driver. that dll is related to the integrated Intel GPU. oughta fix it right up.
