CPU meter suddenly shoots up to 100% and system shuts down

[Vetrics]

Hi All,

I have DELL INSPIRON 15R series laptop with WINDOW 7.

Hardware:
i3 Proc
320GB
4GB DDR3 RAM.

Problem: MY CPU meter unncessarily shoots upto 100 and system shuts down

Instances:
1. Twice, When I was on video conference with 3 of my friends (Google Plus Hang Out - Google Chrome browser)

2. When I tried to Mix audio and Video in Windows Live Movie Maker

3. I use a Software called Fruity Loops for Music Programming. I had created a project 4 months ago with this software. It worked fine then. The CPU consumption to play my program live was Nominal.
I opened the same project a couple of weeks ago, and the project wouldnt even play.
It drags... CPU shoots up and system shuts down

I removed all the unncessary programs that I had installed on my machine. I still face the problem.

The problem first occured, when I used Adobe Audition to remove noise from a recording.


Could any one help me out of this??

Thanks,
Vetri

Maybe its shuting down because the processor overheats, time for spring cleanning?

Can you open task manager and see what processes are taking the most CPU usage(or a screenshot)? I may be having a similar issue with random high CPU. As for the computer shutting down, I agree with OldMX that it is shutting down when it gets to hot to protect for damage.
