For the past couple of weeks I have been getting this error message (see attachment) every time I turn on my computer, try to run a program, shut it down and sometimes just randomly. Sometimes I have to click the OK button for a few minutes quickly before it will go away. When I start my computer up the computer screen goes black after the Windows 7 startup and won't go to main screen for a while until I have clicked it many times. I have no maliware, viruses, I have disk defraged the computer and tried deleting/reinstalling The Sims which came up on my CPU when I looked up.dll. Any ideas would be very grateful!
