Window leaves white space when dragging window

Hello, I have about 8 "exact" systems (Dell optiplex 780 with a graphics card).  One of the systems has a problem.  After the system is started and logged into Windows there are programs that are suppose to start and they do.  When the windows is moved, the original location where the window was leaves a blank space, the graphics are not working correctly.

I updated Windows, and all firmware and BIOS.  Still it continues to behave this way.

Ay suggestions for fixing this.. It does NOT happen to any of the other workstations.

This is either going to be memory, process or OS/application related.  Likely scenarios are:
1.  Application thread is not getting priority so that UI messages are not processed by the operating system.
2.  Application is blocking UI thread (not an uncommon scenario) causing UI messages to not get sent to the operating system.
3.  There is not enough memory in the system to handle the current workload imposed by the operating system, it's services and any other applications that are running at the time.

You can use tools like Process Explorer to determine memory/processor utilization.

If you open an application that covers the whole screen and then close that screen does the white space still appear or is the area (probably the desktop) restored back to normal?

I'd suspect something hogging CPU usage that is running in the background but again it could be anything.  

it_saige has made valid suggestion you need to especially consider.

I would uninstall and reinstall the graphic drivers from the manufactures website.

Just to test that it doesn't have anything to do with the monitor refreshing try swaping monitors with another desktop.

or this one :  http://www.ozone3d.net/benchmarks/fur/

have you run a chkdsk to check to see if the desktop has a disk issue?
Also, what is the background?
If it is a solid color, black or blue, does this still occur?
Is it with certain applications, or all of them?
if you kill explorer.exe and launch it again, does it continue to happen?
does it happen right after reboot, or randomly?
how much memory does it have?
what processor is in it?
does it have the original power supply and hard drive?
What OS are you running on it? (X86 or x64)

it also happens when you are low on system resources, so check how much ram is used and free in  task manager

The problem was a hardware issue with the video card.  Replace video card and all is ok now.

Thank you for the advice.  It took me a while to get the video card and replace it.  That took care of the issue.
