@frank grasley,
Are you trying to ask how to get it started?
Replace the part that broke.
If your next question is what part broke:
You tell us, we aren't there and you gave us no information.
If you don't know how to test for what part broke:
Take the computer to someone who does.
If you want advice:
Buy a new computer, it can end up being cheaper than trying to fix your 6-year old computer.
