I have an Acer Aspire 5 just over one year old. Two days ago, the fan started running continuously and the hum is making me crazy. I have updated Windows, confirmed no virus or malware, closed all unnecessary programs, changed the system usage mode to silent (this did nothing) and turned the laptop off overnight (twice). CPU is running less than 10%. Once the laptop turns on, it takes about 20 minutes before the hum starts. Do I update the BIOS? When I search BIOS updates on this site for my laptop model, there are many options to update/download. How do I know which one(s) to pick?
