Code execution has been interrupted error on my macro file

I have gotten this "Code execution has been interrupted error" from time to time. I usually spend about 2hrs trying to figure it out looking at my code. Once i realize i have no idea i shut down excel, if error still occurs then i reboot system and after reboot


the error is gone.

i have NO idea what causes this error or how to identify that the error requires a reboot or why?

Does anyone have any ideas on this........i spend way to much time on this kind of thing.......any suggestions would be appreciated.

enclosed is a pic of the error and what the help dialog says
