CoolBee: First, the crashing had nothing to do with your OS, but with hardware. Either the machine was full of dust, or it simply was badly built and unable to cool it self down properly when it got to hot.
And secondly, to put on my geek fascist hat

, people who don't know the difference between a steering wheel and a break pedal are not allowed to drive cars. Same should go for computer users, if you don't know the difference between a hardrive, CPU, Windows and MS Office, you should stick with pen and paper! Hackers around the world rely on incompetent computer users to run their botnets, which in turn can be used to bring down important servers and services.
( Don't take this post to seriously, it's all a bit tongue in cheek, although I do mean some of it).
