Although it isn’t frequent, sometimes your computer acts abnormally. From twitches in the screen to making loud noises suddenly, anything is possible. As there is a lot of hardware involved, this is expected.

How to Solve ‘CPU Fan Spins Then Stops’ Issue?
Of all the reasons that your CPU fan might stop, it isn’t the memory to be blamed. Rather something very important has gone wrong this time.
Here are the two problems that shut your fan off for a technical reason.
1. Processor Not Compatible With Motherboard
While upgrading our motherboard or processor, we don’t pay much attention to them. Although most of them have the same port or pins and will fit on your motherboard, some don’t fit with one another.
This is the case for most users. We have done the same with our PC while an upgraded processor didn’t fit with an old motherboard. Hence, we had to dial back to the series that fitted with it.
Check your processor and motherboard compatibility. If you are not familiar with these things, you can go to your local computer store and they will solve it for you.
2. Outdated BIOS
Another reason for the CPU fan to stop working after a few seconds is that while you have upgraded your processor or motherboard, the bios need to be updated too. Old bios on new hardware don’t work side by side.
The solution is pretty straightforward, you have to update your BIOS and everything will be fine.
To update your BIOS, you have to know the information about it and then download it from the manufacturer’s site.
Press Windows+R and then type “msinfo32”. This will bring out your computer’s system information. And you will find your bios information under “BIOS Version”. Search with it and download the file.
