Main Question or Discussion Point

Hi, just curious. I am trying to fix my Vaio PC , model PCG -71318L. Intially, PC worked well for a few minutes but eventually froze.
I thought it may be a hardrive thing . The computer had been on uninterruptedly for a long time, so I turned it off to "let it rest". After an hour or so, I turned it back on and ended up with a color screen and the lower left part of the bottom was overheated. EDIT: I tried a search, but found nothing useful.

What do you mean by color screen with left part of bottom overheated?

You mean you got like a blue screen and the bottom left looks a bit multicolored and wavy like when you touch the screen enough to deflect it?

Anyway, here's a bunch of steps to follow from SONY:

You could try removing the battery and then replacing it to see if that solves the problem before proceeding thru the steps.

Also have you tried to boot via CD-ROM or via USB with something like Knoppix:

This could help you determine if its hw or sw related.
