[CentOS] Server hangs on CentOS 5.5

+36C and +39C are likely your cpu and motherboard temps. You have to look at
the temps in the cmos and match them.

The +87C is likely just a miss-reading by lm_sensors. Anything running that
hot won't be stable.

I use AMD as well, and lm_sensors tells me something is 128°C.
