HP OMEN Obelisk Desktop - System and Cpu Fan error - 90B

HP Recommended
HP Omen Obelisk Desktop
Microsoft Windows 10 (64-bit)

Hello everyone.

Today after coming home from work I turned on my pc to be greeted by an error message i have never seen before.

The message said that my CPU and System fans were not working correctly and it recommended that i should not use the computer, however after inspecting the inside of my case i found out that the fans were in fact spinning freely and without any issues. After booting up the pc the fans would start spinning on their maximum possible speed. I tried checking for viruses or malware but came up with nothing. I also attempted to download software that would allow me to control my fans, except the only fan i managed to control was my gpu fan. 

I have read up on similiar issues on the internet and even tried restarting my pc, performing a hard restart, checked for bios updates and even tried looking around in the bios settings. Another thing i tried was checking for any driver updates, but everything seems up to date.

 

As it is currently too late for me to bring my pc to the repair shop, i am looking for help on here, hoping somebody could help me figure out this issue.

Any tips will be greatly appreciated and i will gladly answer any questions that might help you come up with any ideas.

 

PS: I suspect it might have something to do with a power outage that happened earlier today, however my computer was not running at the time and i suspect no issues with my power supply, as the fans are in fact spinning.

! SOLVED !

FOR ANYONE ELSE THAT MIGHT RUN INTO THE SAME ISSUE:

After re-checking bios updates even though it kept telling me everything was up to date i found out that my bios was 1 version behind. I manually downloaded it from https://support.hp.com/sk-en/drivers and ran the executable.

After installing the BIOS update everything ran smoothly and the fans were spinning in their usual fashion.

Not sure if the issue was that the bios got confused after the power outage or if it was just out of date, but reinstalling/updating or maybe even downgrading will most likely help.

I hope anyone else who runs into this problem finds my thread instead of stumbling around like an idiot for 4 hours straight.

Cheers.
