I don't know if this is a hardware or software problem. I have my laptop computer fan set to not run all the time in the bios. I have scanned the computer for malware or viruses that could be causing the problem. When I start my computer or when it sits idle for a minute the fan speeds up to max speed even when a program is not running(I watched the task bar). The fan even runs when there is low CPU usage, low RAM usage, and low DISK usage. Also the heat coming from my computer is normal same as it always has been, and the ambient room temperature in the rooms that I use the computer are 60-70 degrees Fahrenheit. I have checked and it is not my Nvidia card that is causing the problems. My laptop before this week has run fine until the fan was acting up. When I start my computer the fan is normal and once I sign in after 15 seconds it runs at full even when their is low CPU, RAM, and Disk Usage, it also runs fast when my computer is idle. I have updated my BIOS and reset some of the hardware on my computer from when I first got the computer and it still did not stop the fan problem. What also bothers me is that the fan runs at full at random times despite the load on the computer, I could be browsing the web or just watching the task bar and still the fan runs loud. I have also unistalled and reinstalled programs that I know can cause load on the computer and it still does not work. At times the computer runs normally but when I am in class or working at home the fan randomly speeds up and is loud. The computer is 4 months old too.
