Hi Everyone I've been having some problems with my Fsx. i got a new computer and installed Fsx everything was fine i got over 20 fps till i deleted Fsx to re install when i re installed Fsx all i got was a serious amount of lag like 1 fps and my loading mouse icon is black instead of white i tried deleting everything from Fsx but still no help if anyone knows what could be the problem feel free to help.

I take you have installed service packs 1 and 2? 

 

 

till i deleted Fsx to re install when i re installed Fsx all i got was a serious amount of lag

 

Something is seriously taking up system resources to cause the mouse cursor to go black.  You will always run into problems if you simply delete FSX and then try to reinstall it.  I like the following guide for uninstalling/reinstalling FSX - http://support.precisionmanuals.com/KB/a87/how-to-uninstall-and-reinstall-fsx.aspx.  The only thing I would add to the guide is to run a registry cleaner before reinstalling. 

 

Best regards,
