next check hardware
you want clear me ?
Yes please
Please help me.
I ran "diagnostics" because there were many times when the boot logo did not transition to the boot screen.
After that, the PC would power down at the memory test point, and the boot button and fan would repeatedly glow and move for a moment.
Could this be a BIOS failure?

that shows BIOS no problem next you need to check the hardware
Understood, sir.
Thank you very much.
When I checked, I was able to output the logo.
However, when I shut down completely and start up, I use "F1" to enter the BIOS, select "Restart" without making any changes, and then try to enter the BIOS again, it freezes with the logo.
When I try to enter the BIOS again, it freezes with the logo. If I forcefully press and hold the power button to shut down, I can enter the BIOS.
Can you tell me what's going wrong?
