About 6 years ago, I bought a Dimension 4300 from someone on Craigslist. It's old, but still in good working condition, although pretty slow from clutter. I want to do a factory restore on the system, but I don't have the restore cd and have no way of remembering or contacting the person I bought it from. What can I do to perform a factory restore? I have the Windows Key and serial number if needed...
