Question

I have an Acer Aspire 5315 laptop that shuts down randomly. From searching the web I see that it's a common problem having to do with the fan not turning off and on properly. I was wondering if you know of any fix other than sending the computer back to the manufacturer. I purchased the computer so I cannot return it to Acer.
