Sounds good, just let me know. And if there's something I don't have, then I'm sure I could find it somewhere around town. I live in Silicon Valley so.... there are quite a few places around here that would most likely have what you're looking for and usually (not always) for good prices.

Honestly, from your description I don't think it's your processor... otherwise your PC wouldn't even POST (Power On Self Test, which is directed by the CPU), it just plain wouldn't start at all. I'm leaning towards a bad hard drive; especially a bad MBR (Master Boot Record) which is on the first track of the HD and initializes the OS after the BIOS has finished its process. If that's the case, there are 3 options off the top of my head that you could attempt to try to recover your data:
1. Boot from the Windows installation disk and run the Microsoft Recovery Console. Once in the recovery console command line type "fixmbr", without the quotes. This sometimes works... but sometimes the drive/sectors are too damaged and it won't work.
2. Remove the drive, buy a USB to SATA/IDE adapter (a device that allows you to hook up an internal HD externally to the PC through a USB port. Think of it as an external HD enclosure without the enclosure; just the connections that you connect your drive to the computer with). They run anywhere between $15 to $30 U.S. dollars and you can get them online like from Newegg.com. Of course you need to obviously hook up to another working PC. Maybe a friends or if you have another system. Once you do this, this defective drive will act as if it's just another external drive and bypass the MBR. Thereby you might be able to pull off your data.
3. If none of the above work then the drive might be in such bad shape that you would have to send it off to a data recovery service. But this option could potentially be VERY expensive. Most people that do this only do it if the data on the drive is critical and they didn't have a backup.
Good luck!
