Cannot open computer icon windows 7 professional

I cannot right click nor double click on computer windows 7 professional.  I cannot open any icon on the desktop either.  It appears it opens, but then parks itself in the task bar.  I cannot right click on it and select Restore, it sits there and does not open.  

Windows 7 professional all update have been performed.  Running Symantec End Point Protection client.  I have this installed on several workstations and have no issues.  This just started about 2 weeks ago.  I have scanned for viruses, not finding any.

Just a thought, Has this computer been working with multiple monitors and now has only the one? often if a program was on the second monitor and now you only have one, the program does not appear correctly.

Startup repair is not going to cure an application fault. the computer starts up perfectly and logs in perfectly.

Try running System File Checker. This repairs some things but not everything.

Open an admin command prompt and run SFC /SCANNOW twice. Allow to complete, restart and test.

Do you agree?  From what you have posted your Desktop is frozen and you cannot operate the PC.

Try right clicking on the taskbar then clicking on Show windows side by side.

I did not have the 2nd monitor turned on when I was trying to open Computer or other folders.  I can't believe I did not think of this.
