Hi Bill,

I had similar problem with MSI motherboard a while ago. I had to update BIOS and motherboard chipset drivers a few times to get it fixed.

Usualy there's a settings or whole section called PC Health in the BIOS when motherboard provides protection from CPU overheating.

>The issue showed up a relatively short time after I bought the machine. Took it back to them and they set it up and watched it and nothing happened ( naturally - customer support in the computer hardware industry just stinks :-( ). The problem was very intermittent and not often. But in recent days/weeks it has increased in frequency to be problematic. Fans are all running and I cleaned the various parts/ports of any accumulated dust. Is there a setting that can be checked to see if the motherboard has overheating protection?
