Hi everyone, I really hope someone can answer this.

For the past two weeks, my pc has been acting like it has a mind of its own. I'll be working it and from out of nowhere a blank black square flashes on my screen. It is just a flash on and off. It is there not even for a split-second.

I was afraid I has contracted some virus so I took it to OfficeMax. They ran diagnostics and my pc came out clean as a whistle. I reloaded my McAfee anti-virus.

Has this happened to someone else?

Thank you,
Kristina
