Windows 7: Monitor flickers when pushing ctrl key

Monitor flickers when pushing ctrl key

Hi everyone.

New to posting on these forums.

I'm an IT professional, one of my friends is having an issue that so far I have not been able to solve.

Every time he presses his ctrl key on his keyboard, his monitor will flicker instantaneously with the keystroke. I have had him remove his keyboard, and using the onscreen keyboard, the same exact issue happens.

This makes me think it must be something software related, but I don't know what... if his registry is somehow corrupt, issue with graphics drivers, some sort of software.

Right now I am reinstalling his graphics drivers to see if these resolves anything.

Also, I'll add this is a brand new computer that I had built and shipped to him. He says its happened ever since he's got it, the past few weeks.

Any sorts of ideas would be great. Thank you

Forgot to add, this only happens when he is in a game application.

I just reinstalled his drivers remotely and it looks like it has resolved the issue.
