Windows 10: PC shutting down on start

Hello,I own Windows 11 home, recently my computer started offering the option to update on shutdown. I did not update. 3 days ago I turned the computer on normally, after about 10 seconds it shut down as in power failure - i.e. immediately, after about 5 seconds it started up again but this time into "POST safe mode" which sent me to BIOS where I rebooted the PC, then it booted up properly. In the evening I shut it down classically the update option was no longer displayedToday the same thing happened. However, this time after the "blackout" it didn't display POST safe mode, I had to unplu

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

After Windows 10 update, PC con't start

Good news, pc is back and running.
zBook was on the right track in that the BIOS was corrupted. However, the solution suggested did not work.
Fortunately, after considerable digging, I found some information on the Gigabyte site. Following their suggestions, I was able to restore the primary BIOS from the backup BIOS. The whole process took less than 10 minutes.
Basically, I had to:

1. Shut off the computer. Unplug all connections to the motherboard except the VGA/DVI output and the keyboard.
2. Press the POWER button and HOLD it. The computer will start and then shutdown. After the shutdown, release the POWER button.
3. Press and release the POWER button. The BIOS will go into recovery mode. A BIOS recovery screen will appear and you need only to select from the options that are presented.

This was a simple solution and I am now up and running.
Thanks to all who provided suggestions.
