Fan Spinning Very Loud then Computer Shuts Down

Asked By Ronald B Cline 45 points N/A Posted on - 11/06/2013

My computer used to work just fine. Until I heard the fan spinning very loud. And now it randomly shuts down. I want to know if this is an issue with my Power Supply Unit or my GPU. I tried to reset the CMOS battery and then turned on my computer but it will just do the same thing. Please tell me what to do next and how can I fix it?

Fan Spinning Very Loud then Computer Shuts Down

The fan spins loudly due to overheating.  You should try to clean any dust on the Fan with the help of vacuum cleaner. Be careful, the Power Supply Unit could be hot.

Also try running eventvwmr.msc through Windows Run interface. Select system logs and look for red or yellow flagged items. It will provide you a reason for shut down or a reason code.

Fan Spinning Very Loud then Computer Shuts Down

Hello Ronald,

There can be any of the two reasons:

1. Your PC get over heated so it gets restarted again and again.
2. You have a low voltage problem in the power supply.

To overcome the overheat problem try to clean the fan and most importantly keep your PC clean from any kind of dust. If the PC fan is not enough than you can also an additional fan for it.

For the second case try fixing the voltage supply.

Fan Spinning Very Loud then Computer Shuts Down

If you notice a very loud noise coming from your CPU cooling fan then the problem is related to overheating of the processor. When a processor overheats, your system or CPU will automatically turn off. You won’t be able to turn it on until the processor has cooled down. Any problem with the CMOS battery will not cause the machine to automatically shut down.

It will just keep on resetting the date and time because BIOS can no longer save the settings due to low battery but it will never shut down the machine randomly. Since the problem is with the CPU cooling fan, the best way to fix it is to replace it with a new one.

When a cooling fan starts to become noisy, it is a sign that it needs to be lubricated. It also causes the fan to spin a little slower than normal that’s why the processor tends to overheat. Try buying a new CPU cooling fan for your CPU model from a local computer store or online.
