Why it's important to keep your computer cool...

Well all, I had one hell of a depressing day yesterday. I was just playing Worms: Armageddon, when my computer reboots for no reason at all. About two seconds later, both of my screens go blank. Then I smell something burning.
Oh shit.
I switch off the power and rip off the case only to find my proccessor smoking. So, I'm without a computer for at least a week (Luckily, I have a little money saved up, so it'll be repaired in no time)
The wierd thing is, my system has never even shown signs of being hot. I thought my motherboard would use it's built-in safety protocols to shut down the computer once it became too hot. I was wrong.
So, I may be in the line for a new motherboard and (obviously a new CPU) heatsink.
Could you guys suggest some combos that I might be interested in getting. I have around $200 to spend. I would like to upgrade to DDR, but that may not happen for a while. So, are there any mobo's out there that support the AMD Athlon XP 1700-2000+ and have DDR slots and SDRAM slots? (I know these motherboards exist, but I though my chances would be better asking you guys) If so, I'll have a fairly good computer once again.
Then I must consider cooling. I thought my fan was enough.. but obviously not. Should I buy a new heatsink? And what type? More fans in the case? Well, whatever, I'd better get back to schoolwork.
Thanks in advance.
