I'd hate for you to sepnd 60 bucks on a new one and that not fix your problem. Try a friends/extra laptop hard drive first, see if that fixes the issue. If it doesn't you may need to look into getting a new laptop.
As for the desktop, the first symptoms you were describing sounds like the desktop was overheating - possibly from either the power supply fan dying (off again on again symptoms) or a CPU fan. Obviously the second part of your story indicates that your power supply fried - question is did it mess up your mb. Check the manufacteres website to see if there is an error code that matches the one your describing. I believe it is just your power supply.
Guess i'm confused... So you used a boot CD and the CD was able to read your hard drive and was asking to install? Because if that is the case then your hard drive works... know what i mean? Or are you saying you used the bootable CD, and it didn't detect a hard drive? Explain that part a little more for me please.
No RPM is NOT constrained by the size of the drive. And you definately want to get a 7200 rpm drive, not 5400. Your hard drive is the slowest component on your system, and you don't want the system sitting any longer then it needs to waiting for the hard drive.

There is a 250 gig SATA 7200 RPM drive. Laptop drives are bit harder to find at 7200 RPM, the technology is there, but w/ the price being higher anyways people tend to shy away from the 7200 ones b/c they are a lot more expensive (w/ 2.5'').
What i meant by overheats was that were any of the fans being blocked, or had dust or possibly not kicking on. Maybe the heatsink wasn't properly seated on the CPU. Just some ideas.
