I recently installed a new Radeon 7770 graphics card in my computer, along with a new 700w psu, it seemed like everything was working fine, then about a week later steam had a sale, i saw sleeping dogs was on sale so i bought it. To my dismay the pc version came with a crap load of problems, at first the game wouldnt even start, then after doing a bit of research i found out how to fix it, but when i got into the game it crashed after about an hour. Since then i have been unable to play. many of my games such as deadspace 2, saints row 3, and sleeping dogs, amoung others will crash to desktop and display not respondin when ever i go into task manager, up until that point i get a solid fps with absolutly no lag, usually with the game somewhere between high to medium graphics, then the game randomly crashes with no rhyme or reason as to why, sometimes it takes 3o minutes other times i dont even get through the load screen. Im also fairly confidant that this isnt a virus as when i run a full scan kipersky comes up with nothing.
