Windows 7 - window focus freezes intermittently

Symptom - can move mouse, but cannot switch focus between windows; focus will be stuck on a window until CTL+ALT+DEL pressed.  This un-freezes things so that user can then left click in another window to switch focus to that window.  (This usually works).  

Tried so far: Uninstalling and re-installing many of the programs; updated several key drivers. Same temporary freezing of the focus.  

Then we tried restoring an Macrium image of the entire C:\ drive from August 2011, long before this problem first occurred.  We had no luck.  There was the same intermittent freezing of the focus.  

We've run HDTune to check the HD - all seems ok and green on every tab.  We ran Windows Memory Diagnostic; this was all clear as well.  I am open to running other types of scans.

We ran two separate malware scans - the latest and updated ESET as well as the latest Dr. Web.  No malware of any kind was found.  

Then we became desperate and re-installed Windows 7 from disk. Before I could even load a driver from the motherboard driver disk, the focus froze again on a window.  As always, we could still move the mouse around the screen, but clicking produced no result.  We could not click on anything and had to CTL ALT DEL to regain ability to switch focus.

Have you tried a different mouse?

Also, does Alt-Tab still work for tabbing between screens?

Check the network port - if it is malfunctioning, it could generate a lot of interrupts.  If you boot with a Knoppix CD and experience the same symptoms, you likely have a hardware problem.

We are trying both of these solutions and really appreciate the help!   It might be tomorrow 3/29 before I know for certain if either or both are the solution to this problem.

Make sure all BIOS settings are returned to default if the PC is overclocked. If that doesn't work, try running with only 1 stick of RAM and see if that makes a difference. Memory scans don't always catch all memory problems, especially if there's an incompatibility issue with the motherboard, etc.

Well, it seems EE has come through again!  I tried all of these solutions, and the one that worked was a change of mouse.  The mouse is very old and well worn; we just missed it when looking at the problem.  Thanks to all.
