BLUE SCREEN CPU Fan (90B) error - HP Pavilion Desktop (570-p052na)

570-p052na
Microsoft Windows 10 (64-bit)

Hi all

 

I get a blue screen CPU Fan 90B error when starting up on my HP Pavilion Desktop (570-p052na) desktop  and if I don't press enter to by pass it will shut down in 15 seconds. 

https://support.hp.com/gb-en/document/c05437318

 

Its a Lubin motherboard 

https://support.hp.com/gb-en/document/c05382582

 

Do I just change the fan on the motherboard? If so, can someone tell me which one to buy and is it easy to change and fix?

I've been pressing enter to by pass and scared it will just break and stop working soon.

 

Many thanks

Welcome to HP Community

 

Yes the Fans needs to be changed but sometimes other components too like Thermal paste etc.

 

I suggest you contact HP Support for Service Options

BLUE SCREEN CPU Fan (90B) error - HP Pavilion Desktop (570-p052na)

For the record, I have a different machine than you. It's a 2017 750-477c

 

I had the same issue starting yesterday. After searching HP's Support, I found instructions that may have helped. I stopped getting the error this morning.

Suggestions found and followed:

  1. Do a Hard Boot on the computer (unplug computer, press and hold power button for 5-10 seconds). This supposedly resets the temperature sensor readings. I did this 3 times with no change yesterday.
  2. Run boot-time diagnostics (Turn on power then repeatedly hit F2 key until Diagnostics menu displays. Then run Component Test on Processor.) That found no problems.

Since it said the CPU fan wasn't working, I took the side cover off and powered it up, just to see if the fan was running. All fans were running -  CPU (on the motherboard), main (on the case in the back) and graphics card (the red one).

And my system came up fine as I was checking that.  Go figure!

 

Once Windows 10 came up, I ran the Windows version of the HP Diagnostics, checking the processor. That test passed.  Weird.

 

The past week, I'd been hearing a fan whining up and down in pitch, so I wasn't surprised to get this error in the first place. I'm going to run the Windows Diagnostics app to run more tests.

 

I still plan to get the CPU fan replaced, since it's been struggling. I'm not sure if my local BestBuy will work on it during the coronavirus shutdown, but that's my first stop. 

 

Good luck!
