MS Win 7 64 bit
New Dell Optiplex 790 System
Just installed two weeks ago - very few apps installed and only a few trusted websites have been visited.

Originally set up and installed MS Office, Adobe Reader, and a few other common programs. Installed VMware vSphere Client. Upon using VMWare vSphere Client for the first time, I first noticed the white/blank square in the upper right corner of my desktop. It has been there ever since, even when I have not used any applications after startup.

I'm attaching a snippet of the affected area of the desktop.

Optiplex 790 PSU failure - Common? <<= Full article from Spiceworks
More recent details have now shown it is a Dell Specific problem -

It is either related to Power Supply Unit (most likely) or Motherboard issue (maybe) - Contact your Dell dealer ASAP -

Quote from Dell spokesperson =
Dell made minor modifications to OptiPlex 990 and 790 motherboards.
Due to the revision the OptiPlex 990/790 system(s) will require installation of either Dell's or an embedded/custom BIOS based on A11 or later on a go-forward basis and will no longer be compatible with BIOS versions previous to A11.

In addition, the engineering team cannot determine root cause without analyzing the failed MBs.
Have you been in contact with technical support to report the failures you are experiencing?

This is not a problem caused by you in any way - It needs to be fixed by your Dell dealer Now -

Edited to fix link -

Frankly...I'd suspect a video function problem, if the only thing troubling you is related to video.

I would uninstall the current video drivers...then reinstall same.

Thank you for the comments/suggestions. I checked the BIOS version on the computer as shipped and it was at A13. Then, I went to the Dell site to look for updates to my system. There was a video update and I completed it, along with one other (don't remember what it updated). After completing those updated and restarting the system, the problem seems to now be fixed.

I appreciate the help!
Bob
