Hello reader, Like the subject says, when I start up a game like Call of Duty 2, CoD Modern Warfare or anything else the game starts .. screen gets black and it pops back to windows. I have checked the latest drivers but I am fully sure I got everything. I think there's something wrong with a driver but I have no clue what that may be .. where the problem is. 99% a driver problem as my laptop is 1 month old. Here my laptop specs Acer Aspire 5732zg 15.6inch HD 4gb DDR 3 ATI Mobility Radeon HD 4570 Intel pentium T 4300 2.1 GHZ 800mhz fsb I have also flashed the right bios .. the latest from the acer website and all the latest drivers. On device management I see no question marks and everything works. Though I have the feeling the driver of my video card is not good or not working fully .. like there's missing something. If not, the games would have worked. When I received the laptop and everything was pre-installed I had the same problem as now. I have upgraded the win 7 home premium 64bit to win 7 ultimate 64bit but still got the problem with all the right drivers. Please help because after 1 month I still have not figured it out.
