I am working on Hells Gate (in my sig), I have started to get these lock ups no mouse or key board response I have done some things to figure it out but to no avail, I posted here thought it maybe Motherboard related http://www.overclock.net/t/1035333/official-asus-sabertooth-amd-owners-club/6530 . I have removed one of the GPU's to eliminate it, still no change, there is no BSOD or any indication, only when I restart ( manually ) I get the usual "windows did not shut down properly" as posted in the link I have done a fresh install on a raw SSD with only ASUS and AMD CCC drivers installed, It locked up before I could get the CCC loaded so I have to believe that it is not a CCC driver or configuration concern when it first started it would not recover (on the original drive), then after the fresh install I noticed that it recovered in a short time (as posted in the link), anyhow could a web browser ( windows 7 stock) cause a lock up/ freeze up? I am not a software kinda person , I will swap out the other GPU to eliminate it after that I am at a loss. any insight to my dilemma would be much appreciated
