Windows 7 32 Bits PC shuts down when trying to debug in Visual C# 2008

[Punkbuster]

Hello guys,
I am running Windows 7 Professional 32 bits and I have Microsoft Visual C# Studio 2008 and when I try to debug a console application (Not sure if this happens in other project types) Something happens and starts to exit all the open programs and starts the shut down sequence!
What is wrong?
I used to have occasional shut downs but that was because my CPU was over heating but now my CPU temp is not more than 48C!

Any ideas?
Cheers,
Punkbuster

What did you do to rectify the overheating cpu? And what is your cpu's temperature parameters?

I checked the temp in the BIOS and I downloaded a tool called nVidia System Moniter
and CPU temp is mostly 45-55 C

And what is your cpu's temperature parameters as per the manufacture?

I am not sure, Where to find out? My CPU is Intel Core 2 Duo E8400 @ 3GHz

EDIT: Here is the parameters 5 - 72.4 C

That is a solid cpu. What is the make and model of your psu and how much wattage does it purport to supply?
