CPU TOO HOT

[Waqas]

OK, Here is the Problem.
I just bough an MSI P4N Diamond Motherboard with SLI technology. I intalled a pentium 530 3.0 GHZ presscott processor with a Masscool H/F.

A couple of days ago my computer kept getting stuck after every 15-20 minutes of use. I wasnt running any games or anything, just browsing. Back than the CPU temperature was somewhere around 45 C Degrees.

I had some SPECTRA COOL Poly-Synthetic thermal paste. But now my temperature is about 56 C degree. But now my computer is running fine ( for about 5 hours)

Any Help Would be nice.
