"while keep on for a whole night it can even distroy your electronic circuits in side..."
I didn't know that. My computers stay on for weeks at a time without any problems.

I did NOT leave my computer on all night. It goes on system standby after no activity after 30 minutes as well as the monitor. And by the way the problem was the cpu. I installed a new one and I have had no problem ever since.
Also I am not rough with my computers ...I take very good care of them.
Thanks any way

Thank you for your input. The beeps were long beeps that just kept on beeping. Not steady but never ending unless I shut the computer down.
Thanks for your help and support on whats his names mention that I was rough on my computer

You're welcome.
I've come to the conclusion that people who don't know how to use capital letters or punctuation can be safely ignored. If they can't master this simple process, how can they know anything about computers?
