Windows 11 Upgrade Guide
My PC will suddenly shut down and the fan will produce a loud noise. I need to force it to power off, sometimes it will produce 3 long and 3 short beeps, and I have no idea what it means.
When it works normally, it will never shut down properly, I have to keep pushing and hold the power button for a long time to shut it down.
I checked the HP Support Assistant, there is nothing new for updating BIOS.
