Desktop blanks every 30 secs or so for a second (icons and wallpaper) except for any active windows.
Windows update had stopped working and I ran the windows troubleshooter to fix the problem. It did but now have this desktop refresh problem.
I have all the latest updates and have used Windows virus checker and spybot to scan the hard drive. nothing found.
