try as i might i cannot seem to find the intelgraphics control panel.

crickets???

A couple of things to try:

1. From a command prompt, run as Administrator, type this: sfc /scannow

Let it run, takes a little time.

2. Run Windows Update, and make sure that in Update, the switch "Receive updates for other Microsoft products" is set to On. Important: leave this switch On in the future.
