My wife's computer seemed to be working normally until this afternoon. When she tries to access the internet (IE) all she gets is a white screen. My computer and my sons computer can access the net fine. My son uses FIREFOX and I use BABYLON. I did however try IE and I had no issues. Can't seem to find the problem.

Most probably addons or plugins. Increasing problem these days...

Try to browse now.


Still not working? Then download the following program. Small but very powerful program.

What happens if you load Firefox on her PC? That would tell you if it's the browser or some other issue.
