Hi all, I was wondering if anyone else has this problem?

I have recently updated to windows 8.1 on my vaio pro, and now when the screen goes to sleep, I am unable to get it back on without hard rebooting the vaio. I have also noticed that, if left alone/inactive for a while, the machine randomly shuts itself down, losing anything I was working on at the time.

I have it setup in the power options to never turn the machine off, but to turn the display off after 10 mins.I have also updated all the drivers on the downloads page, but none of them seem to sort the issue.

I have only got the vaio a week now, and it's seriously starting to annoy me, especially for the amount of money it costs.

Any help would be much appreciated.
