My PC is randomly shutting down and rebooting. Not over-heating (31 degrees during some failures) the OS is a fresh install of Windows 7 ultimate (64 bit) no warning, no overheating, doesnt even need to be doing anything. The Pc will shut down if nothing is happeneing or if you are using it and it happens at different times could be minutes could be hours. help?

That 31C is just the CPU.

Now find the other few dozen chips and get readings on each one. I'm using a Laser Spot Thermometer when I go looking for this.

But unless there is more about this PC. I'm going with the usual. A new tech that is looking at just the CPU temp.

follow H50 hookup recommendation to connect fan to CPU fan header and the pump to steady 12v?

There is a clue there.

I can't find the power supply but those Nvidia 9600's are dropping like flies after a spray of fly spray.

The water cooler is often used by those that overclock. So don't overclock.

And again, it appears you got my message that measuring the CPU temp is not enough.

Answer
MSI motherboard...
by mrwezz123 / July 12, 2012 8:18 AM PDT

if you're specs are correct...overheating shouldn't be the problem, especially with that water-cooler on the processor.

Sadly...MSI isn't known for awesome quality motherboards. That's where I would bet my money on what the problem. is. It's not an easy fix, but put money towards an Asus motherboard and see if the problem progresses.

Or of coarse you could try sending the motherboard back and see if it's under warranty.

Best of luck.
