My comp get hanged very often some time the same programe open even if we don't open it why is it so?

First its not a good idea to piggyback on someone else's question, especially when it has nothing to do with their question. So I moved your Q to its own thread.

Second, if a specific program is causing you to hang, uninstall and reinstall the program.

Sir
I did as u hv advaised me it worked
Thanks
