This forum helped before with a BSOD I was experiencing. It turned out that my Logitech mouse drivers needed updating.
Now the same computer has another problem. The screen freezes regularly, soon after startup. There is no BSOD, the screen just freezes, i.e. the second hand on the desktop clock stops, I can see what I was working on at the time and the PC must be forcably restarted.
The PC is an ASUS G73-JW. It is running Windows 10.
Removing the power cable, then removing the battery for a minute, and then returning both gives several hours of uninteruption but the freezes have always returned eventually.
