Video Card problem?
So I have a relatively new computer that has always run pretty well, but lately I'm having a problem with some things showing up on the screen. When I open Excel once in a while, for example, some cells show up as gibberish and some don't show up at all. Of course it's not happening right now so I can't take a screen shot, but next time it does, I will.
Any suggestions anyone has for me to test whether it's working properly or not?
It's a 768MB eVGA GeForce GTX-460.
