Hi there,

My Win7 PC recently started to freeze randomly. No harware or major software change made, and no specific circumstances I can locate the freezing depending on. I suspect the GPU, but any FurMark stress-test runs well. However, when the hanging occures, my secondary monitor is not showing the mouse pointer, the cursor itself becomes distorted. The final step is the OS freezes totally, no blue-screen, just nothing respons, even the CapsLock and NumLock dies.

As I use it for working (PS, Indd, 3Dsmax, etc) I tried to stress-test the setup, I let it render a huge image and started a FurMark benchmark at the same time for an hour, without any problem. I have the feeling maybe the hanging occurs more on near-idle state. CPUID shows >90 °C when idle, isn't it too high? It drops on any stress.

Any advice welcome, how can I locate the problem! Thanks in advance.



Setup:
i5-2500K @ 3.3Ghz
16Gb RAM
GeForce GTX 460
Win7 Prof. 64 Bit

either your mb isn't reading the temps right or something on your board is massively overheating... since you're freezing up i'd think something is massively overheating. pop the size of your case open, and stick a room fan in the opening, set it on high and see if you have the freezing issues any more.

Okay, it seems your advice is a good point to start. The temperatures dropped with the room fan, except the CPUTIN and the AUXTIN. AUXTIN is even raised. Frozen as well. Am I heading to a mobo replacement?

The cooling block on the mobo (under the GeForce) is really hot for my hand, the others are fine. It's an P8P67-M Pro.
