Broken Laptop Fan

For some unknown reason, my laptop fan went out. So I can only use the computer for a short time. I am not able to record any songs. Anything that requires high processing heats the computer and it shuts off by itself with no warning. It does this to protect itself from permanent damage. I will be looking into the problem. If it just needs a new fan then I can get it taken care of with a $10 order. I was successfully writing a song the other day before this all happened. It will have to wait now.
