I cannot get the computer to do anything. I get a code at start up . 6.640648] Kernel panic - not syncing: Attempted to Kill init| exitcode=0x00007f00
Presumably you are trying to boot from disk. Will it boot from CD/USB? If not you may well have a hardware problem. You could try booting form an Ultimate Boot CD which you would need to create on a working PC but it would then allow you to test the CPU, memory, disk etc. The Ultimate Boot CD is available here. If this CD won't boot either, you have a very sick machine indeed. In this case, check the power supply, replug everything pluggable, but if the problem remains it's probably time to bin it.
