Earlier I was playing the Battlefield 4 beta, with no issues. I got up to do something, and when I came back, my wallpaper was gone(reset to black), I couldnt connect to the internet, it says i have no sound devices, and my overlay that makes Win8 work like Win7 was gone. I suspected a virus, so i ran kaspersky and malwarebytes, neither of which were able to find anything. I then attempted to refresh/rollback my pc. It says it cant do either because of a shadow copy error. I dont know what to do. i have important school stuff i need to be doing now, so a fast response would be appreciated.
Cheers
