okay i have a problem with my computer and i am not very good with computers either. look my computer shuts down by itself after a while of using it and when i try to TURN it back on it says cpu overheating or sometimes it says failed overclocking but i have not overclocked it or done anything since i bought it. my fans work fine and it has never done this since i bought it like 3 years ago so i don't know how it's overheating. the only way i can get back on is letting it sit for a while, o and when i try to burn a CD it will shut down instantly can somebody please help me.Turn computer off. Open the case. Use a can of compressed air to clean it inside (do NOT use vacuum cleaner!).
While cleaning fans, hold their blades with a pencil to avoid any damage.
With case opened, turn the computer on, and see, if all fans are running.

When done...

1. Please, post some computer info:
- processor type, amount of RAM (hold Windows key, hit Pause/Break key)
- hard drive size/free space (open "My Computer", right click on hard drive letter, click "Properties")

2. Download, and install SpeedFan: http://www.almico.com/sfdownload.php
