Booting into X, or to level 3 ? Booting into X it could be a video
problem. Configure to boot to level 3 till you get things sorted out.

Most AMD proccesors have a failure temp of ~90 to 95C internal
core. If 59C is from bios it's pretty much useless, the system has just
booted and the cpu is under low load. Your cpu heats very rapidly as
soon as you begin to boot into an OS. If it's from lm_sensors, it's
comin from a probe (thermistor) that either reads one of the cpu's
pins, or is in contact with the die. From a pin is slightly better,
but in either case the reported temp is 10 to 20C less than the actual
internal core temp. So 59C could mean a core temp closer to 79C, but
probly ~low 70C's. Anyway, it's too high. You want to see reported
probe temps of 45 to 55C under 100% cpu load, 40 to 50C is better.
Your cooler is probly fine, but do you have it mounted with a
thermal pad or grease? Grease is much better, specially over time. Your
case temps maybe too high to let the cooler do it's job. Take the case
cover off and point a table fan directly into the box aimed at the cpu
and chipset heatsinks. Does the problem go away? If it doesn't, next
likely culprits are marginal power supply (is yours AMD approved?), or
marginal motherboard/ram (they work together, equally important). Try
testing with memtest86, the rpm is on your CD's. It'll create a lilo
(or grub) option to boot 'memtest86-xx'. Let it run overnight. You
should see -0- errors.
Your question is not off topic. IMO, most problems reported on this
list have a basis in hardware and configuration, while Mandrake gets
blamed. At least you've yourself pointed in a good direction, as
hardware problems should always be checked and eliminated first ;)

Also make very sure that the heat sink ledge is oriented correctly. If the heat sink is
turned around then it may not be making contact with the cpu core and overheating is very fast.
It can be put on incorrectly.
