Windows 7 My background looks strange :S

[Audrey Bianchi]

Hi all, my background doesn't look good. See attachment. I use windows 7 pro x64 and ATI HD4850. Anyone has any idea why?

Hi Audrey,
How long as the problem been around? Did you change anything or have you recently updated your graphics driver? If not it might help if you install the latest version. Also have you checked for malware? Run a security scan in case you haven't.
