Thanks for your thoughts...
I don't know that I'll be able to fix the failing hard drive, if that's the issue. VPR Matrix was a brand exclusive to Best Buy, and when I call customer support, no one there has ever heard of it. I believe I have what was the last model they ever made, and their website looks the same as the day I bought it. I can't do anything with it now, because what did run from the restore CD removed the operating system, and I'm not sure what do do when I turn the machine on.
With regard to the temperature of the machine: It is not overheating. In fact, I waited a day before running the CD again, and it shut down within a few mintues, and it was barely warm to the touch.
I'm thinking it's a lost cause, but I'm bringing it to Geek Squad for a "free consultation" where I'm sure they'll just tell me they want to run some diagnostics on it, charge me a ridiculous amount of money, and then say it's dead.
Might be time for a new one.
Thanks for your help!
