That's it. After reading that stuff, I am officially giving up on ever running Linux as an OS that was not installed when purchased.
I am no longer convinced that it wasn't dual booting Linux that toasted my last laptop.
The cooling system might not work!?!? What kind of crap is that?
I want to sincerely thank you for all the help you gave, but I'm done with this exercise.
Based upon the experiences you've had I don't blame you for your suspicions and for feeling as you now do. In your position I'd feel the same way.
I've tried and immediately discarded a number of other GNU/Linux distros which fell on their face right out of the gate when run on the hardware which I currently own, even though said distros have allegedly worked well for others on their PCs.
With the irritating exception of Ubuntu Studio 10.04, the Ubuntu family of OS' has worked better for me than either Windows XP Pro SP2 & 3, or 64 bit Windows 7 Home Premium on the modest hodge-podge of PCs I use.
When it comes to running GNU/Linux on old (or new) ostensibly Windows-only consumer grade hardware it is prudent to do some thorough research beforehand as to which distro(s) to try.

The Recommended Hardware List:
"Recommended hardware is hardware that Ubuntu users have had no problems with whatsoever. They don't need extra tweaking or special drivers or configuration file editing..."
However, when it comes to making a strategic purchase of
new hardware for personal use, there are a growing range of bona fide GNU/Linux PCs to choose from...

...in addition to the offerings from long-standing, dedicated GNU/Linux PC vendors mentioned and linked to earlier in this thread.
On the pro side of things, whether it's Google's and Hollywood's adoption of GNU/Linux (also mentioned earlier in this thread) or these more specialized usage examples...

...the growing - and preferred - deployment of GNU/Linux in a wider range of computer fields will only further encourage more hardware vendors to hedge their bets by ensuring the fundamental compatibility of their products with GNU/Linux in addition to Windows (and whatever else the future may bring).
More choices, more voices...

"...Perhaps with the rise in popularity of Linux based appliances, more manufacturers will start to support Linux which this will trickle down to the desktop. Devices running Linux will be more compatible with a Linux desktop..."
