Suddenly shut down and strange sound

HP Recommended
OMEN by HP Obelisk Desktop 875-1055xt
Microsoft Windows 10 (64-bit)

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.

Hi:

 

3 long and 3 short beeps/blinks

 

According to the chart below, it appears your PC has a video problem of some kind.
