ASUS P5Wd2 Premuim Temperature Problems

[rlrcstr]

This machine has been running pretty well for probably close to two years but lately it's been complaining that the CPU is too hot. And twice now it's gotten in this mode where it just turns off a few seconds after I power it on. Doesn't even have time to complete the full post.

So after it complained last time about the CPU running too hot (69 - 72 degrees celsius) I turned it off to check the temp myself and nothing on the motherboard is hot.

The CPU heat sink is not even warm - the case sensor says the heat sink is at about 24 degrees celsius. (I shoved the case's temp sendor between the blades on the sink.)

And if I remove the fan and heat sink, the CPU is barely warm to the touch.

Is it possible that the MB temp sensor is bad? Or is this, perhaps, not really a temperature issue? At the moment, I can't turn my machine on. It just turns itself off after a few seconds without any error message. And it seems to me that it's been plenty of time to cool down if it even was running to hot.

Any ideas? Thanks.

Well, it's definitely not temperature related. After sitting all night, the machine dies again this morning just a few seconds after powering it on. It gave a quick message about issues with overclocking or something before it turned itself off.

I'm not overclocking my system, so I still don't know what the problem is.

Any insight here would be much appreciated.

hmm... powersupply going bad could give you reboot problems. sounds like you might have a bad powersupply.

Already tried replacing hte P/S. Same behavior.

It's either the MB or the CPU. Is there any way to test a CPU without having another MB to plug it into?

try updating the bios for the MB
