Hi everyone, im new to the community.

I've searched my problem, but i just got 2 posts barely related to mine, without answer:

The thing is, when i turn on my notebook, the cpu fan spins until windows start loading or so, maybe a sec before. So when im working with my laptop, it starts to freeze, because the cpu fan is stopped.

I have been using same Windows 7 and configuration since i bought it a year and a half ago.

My Laptop config:

Windows 7 Home Edition (updated)

i5-2410m

4GB ram

650 gb HD

Before i realized the cause of the freeze problem was the cpu fan, i thought it was my windows, so i decided to format it and give a try to Windows 8.1 preview. So now it has installed Windows 8.1 preview (clear install).

It's a generic one from Argentina, thats why i dont give info about the brand.

What should i do to fix this problem?

The system fan is managed by the system BIOS in the system and may also be managed by operating system's power savings features.

In this case, there might be a conflict between your system BIOS and the operating system settings.

You should check directly with your system manufacturer to troubleshoot on this issue and replace the fan if its necessary.

you say your fan does not come back on after startup? if not does it overheat and turnoff ?i mean turn computer off? mine is a acer but mine has a way to turn on fan manually, you have the manual that came with it?.
