I put a new fan in my toshiba laptop and now it wont turn on. It will now power up for about two seconds, I hear the fan spin then it shuts down for good. What do I need to do? Please help!

I would reseat the heatsink and insure that you used a very small amount of thermal paste, as a bad fan connection to the CPU will very quickly overheat and shutdown the system.
