Windows 10: Turned on my laptop and suddenly my fans start spinning like crazy.

I was playing The Simpsons Hit & Run yesterday for almost 3 hours, today I turned on my laptop and suddenly my fans start spinning really really fast. Although everything on my laptop is working smoothly, the fans were really fast. After half a minute, the fans returned to normal speed. I've cleaned the bottom of my laptop to make sure there was no dust where the fan was. Does anyone know why this happened?

My laptop fan is going crazy and won’t stop spinning

I have had my laptop for abour two years now and it has been working fine until about two weeks ago when the fan started making grinding noises and was on all the time. All of a sudden though my laptop fan started going crazy, it is loud and seems like it
is spinning really fast. The laptop doesn’t seem to be heating up. I turned off my laptop and left it over night but the next morning when i turned on my laptop the fan starts spinning right away and it still makes the loud noise.

Laptop has no display and fan not spinning. But power LED is on

Please help me. I have an Acer Aspire 3 laptop.

It suddenly begun to exhibit no display whenever I turn it on sometimes. And when that happens, the fan will stop spinning too.

I wonder what my problem is. Is it my motherboard? Power supply?. I tried the solution to attach an external monitor to the display and press the key combination "Fn" + display output but nothing happened.

 

Laptop fan not always turning on


Hello,
I am having an issue on my Inspiron 15 where my cooling fan doesnt always start up. For example, ill start up the laptop, and start web browsing or playing a game, and the fan will never turn on. I have had it overheat and shut off a few times. But if i restart the laptop manually (start>power>restart), it will spin up automatically as it should. But then after a few more restarts, i will have a session where the fan will never turn on. Right now my only solution, besides a restart, is to use the program Speedfan, and ramp the fans to 100%. Does anyone know why its doing this? My other Inspiron 15, running a Broadwell i7 and Windows 10, has no issues at all.

Thanks for your time,
