So my laptop's going on three years old here. And just the other day, it was working perfectly fine until I noticed it was getting insanely hot. Not terribly long after that, it suddenly and without warning shut down. It was when I had turned it back on that I noticed that my fan wasn't working. It's now been roughly a week, and the fan hasn't come back online, and since it's the beginning of June, my laptop is having some major heat management issues. So, I don't want to have to crack my laptop open to take a look inside, but I fear it's my only option. I've tried using compressed air, or searching for any way possible to start the fan up from Windows, but all hope seems lost. Any suggestions on how to fix this problem?
