Overheating CPU Shutdown Help

[young7allah]

How do I get my system from getting too hot & shutting down? I have the GTX 550 Ti with 750 watts power supply.

What else is installed?

System age, condition? Has the case ever been cleaned?

Update your post with full hardware specs and OS.

Component makes and models?

Especially PSU: age, condition?
