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

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

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.
