I'm not sure if I should be posting here or in video, but because it effects the whole system, I'm posting here. Every time I launch a video from a browser in desktop mode (haven't tried Win 8 mode), whether it be Chrome, Firefox or IE, my pc locks up. The mouse pointer moves, but keyboard function and click commands are locked. It's very frustrating! I've updated all software and hardware. Cleared the cash multiple times. Even run Dell diagnostics to try and figure it out, but nothing is working. My pc has the NVIDIA GeForce 720 GPU and my system info is below:
I can't be the only one experiencing flash problems. Any help is appreciated.
Edit: I should add that sound still plays while pc is locked up.
