Screen Resolution

My desktop resolution continually changes by itself.  For example, even though my background is set to the blue Sony VAIO wallpaper, green streaks and sparkles often appear, even surrounding the Windows logo when starting up.  Then, the desktop resolution may suddenly return to its normal appearance and stay that way for awhile, anywhere from a few minutes to perhaps a whole day.  I have even enlisted the help of Sony tech support in resolving this issue, and just when they think they have fixed it, the problem returns.
