Why does my monitor get jittery when I access my contacts?

Episode 1482 (48:48)

Paul from Riverside, CA
Google Chrome

Paul has a Dell workstation running Windows 7, but when he opens the contacts, the screen goes wonky and it jitters to the point where he can't use it. He swapped devices and it doesn't repeat, and it's not the cables. Leo says that narrows it down to the video card. But he tried it with a different monitor and it does it. So that indicates a weird browser problem that gets triggered by the monitor. Leo says to boot into safe mode and remove Chrome. Then he should try and reinstall it. It could just be a bad install.
