I've seen a few people mention this problem around the interwebs, but have yet to find a solution.
I just bought my Acer Aspire S3 with Windows 8 about a week ago. I've already had one complete system freeze and had to do three forced restarts (at the power button).
The first time, Windows froze up while I was running firefox with a few tabs open- nothing else running. The screen froze and I couldn't start task manager or do anything else.
On another occasion, Windows started to update with no warning, and then spent the entire day preparing to shut down without ever actually managing it.
Is this a Windows 8 problem or a Windows-with-Acer S3 problem? Like I said, I've seen others mention it with this model. Any suggestions?
