Same problem I was also facing.


It is because memory required for C/C++ in Windows Xp is large.


So if you upgrade your RAM it will do.








2nd option is not to run that C/Cpp in full screen.


If you are using dos based C/Cpp like TurboC then use alt+enter and use it in normal screen and not in full screen.





It reduces cpu usage.








In case after that you are still in problems then select idle memory/usage option properly from properties of dos based programs.


Under memory you see idle period option. Increase that. It will also reduce your CPU usage.





Thank you.
