Any question answered...

Ok, one for the computer geniuses...

Today my MacBook wouldn't start up. It chimed, had the grey screen with Apple logo and a never before seen progress bar that never filled up. The mac then turns off.

I restarted it using the install disc and used Disc Utility to see what was up. After trying to Verify Disc it basically said it couldn't because the drive was fucked.

I then used the diagnostics to run an Apple Hardware Test which then told me that the hardware is in top nick. I'm currently running an extended test which takes over one hour apparently.

It's a 2007 13" MacBook running Snow Leopard.

What the fuck is wrong with it?

Does anyone know of a list of CPUs showing speed, clock speeds, power usage and temperature?

I'm looking for a low power, low temperature CPU to replace a Pentium M.

Come on computer geeks, help us out!
