But Electrostatic and computers?
Hmmm, I'm amazed your system didn't show other problems
Many posts over the past several years about drivers, reinstall OS, etc. but nothing worked for me on my new Toshiba A205-S5804 notebook until I turned off my electro-static air cleaner to remove & clean the collector plates. It was sitting under the laptop under the table. That was the cause. I moved it a few feet away and that fixed the problem.
Thanks to all the previous posts - there were some that talked about electrical interference but usually from wireless mice & keyboards.
