ASUS A7V frequent hangup

[UltraMagnus]

I recently bought an ASUS A7V motherboard and a Thunderbird 900. I installed them in my system, but when i turned the system on, the temperature of the CPU went from 32c to 78c in a few seconds, then the system hanged.

I first thought that it was the CPU that was receiving the wrong voltage, but Vcore in BIOS is 1,75 which is OK. I then thought that it could be the motherboard itself since other users have experienced similar system hangups and also the fan was running at a very high speed (12053 RPM, which is the 2 times the rated speed for the CPU fan!), but now i don't know what it could be. I've checked the CPU fan and it is in contact with the surface of the CPU correctly so either the CPU was damaged from the beginning or the motherboard is damaged. Any ideas?

Well, actually, that's about three times my speed right now.

The CPU fan's RPM is probably just a bg that causes it to report a high RM for like 15 seconds into looking into the hardware monitor.

As for your CPU temps, make sure that your HSF is mounted good. If its crooked and there isn't a good contact, this may be the cause of your problem.

Mine does the same when I first look at the hardware monitor but if you move selector down over the fan speed, the rpms will drop to normal, as well as the temperature.
I'm using a PEP 66 HSF and you really have to position it right on for it to make good contact with the CPU. Make sure you are using heat sink conpound as well and only put it on the cpu chip, not the heatsink. Many problems with HS compound is most often, too much is applied and it almost acts as an insulator.

Try that and see what happens!

Well, i don't think that the CPU chip isn't in contact with the heat sink fan since the chip burned a small mark of the model and brand of the CPU into the interface material of the heat sink (I use a Chrome Orb fan). So, the interface material is busted and that kind of proves that there was infact contact.

I'm wondering if it could be the CPU that is bad.
