If you have any ideas as to what we could do to get it to boot, please share them. I’ve tried everything John suggested and he appears to feel that it is hopeless.
Unfortunately, he gave you all my ideas. When you get your new computer, make a system restore CD. I’ve had that work when the computer won’t boot up. It does take you back to a previous image, but that is better than not being able to use your computer. :(
