Not sure which forum category I should use, thus using software (for Driver Problems).  Various times to fix a device you can go into Device Manager  and uninstall the driver, go to top of page click on Actions and click on Search For New Devices.  I am under the impression this will uninstall the device driver, then reinstall the exact same driver (code).  Why does this work?  It appears that the exact same code is now reinstalled and many times fixes a problem.  I have used this technique on mouse driver, internet driver, keyboard driver.  THis is a good and easy first process to try and make a quick fix.

 

Again, I am just trying to figure out why it works - I know I am missing something.  As an ex-programmer trying to figure out why the same code now will work when it had stopped working.

 

Why or under what circumstances does the driver code stop working, and then why does a reinstall of it at times lets it start working again.

The drivers can become corrupted, which is why a re-install will fix the problems.

As to how they get corrupted, that's anyone's guess...
