PC Turning on and off

[Tommy]

Hey!

I enabled secure boot in the bios setup and I clicked exit and save settings.
since, my PC turning on and off.

I tried everything.
I removed and install the cmos battery - did not work.
I removed and installed the RAM - did not work.
I checked all the cables - everything is OK.

someone may help in this issue?

I enabled secure boot in the bios setup and I clicked exit and save settings.

If you turn off does that make a difference?

Secure Boot should have been activated prior to Windows installation.

Secure Boot should have been activated prior to Windows installation.

I can not turn off my personal computer because when I turn the PC, 5-10 seconds and it turning off automatically,

I know Secure Boot should have been activated prior to Windows installation but my Windows 11 has been activated.

Secure Boot must be enabled before an operating system is installed. If an operating system was installed while Secure Boot was disabled, it will not support Secure Boot and a new installation is required.

But my PC turning off and on.
I can’t see anything.
what can I do?

[Rustys]

Let’s see if the works.
Remove the HDD access the BIOS and turn off Secure Boot.

@Tommy - any luck?

I do not see any display and the PC turning on and off.
The PC is 8 years old, maybe the graphic card is the issue or the processor.
I tried everything that was suggested here and anyhting did not solve the issue.

[Bruce]

I would be using another PC to create a bootable USB stick with the Windows Media Creation Tool.
if you want data off the current drive, you’ll have to put it into another PC or use and external drive caddy.

[Rustys]

Causing this could be loose hardware.
Loose power cable.
Bad PSU.
The power that is plugged into.
Hardware failure

Like you state

The PC is 8 years old.

Like @Bruce has stated put the drive into a catty and replace the system and use it for storage.

@Tommy - any update?

[PeterOz]

Remove the HDD access the BIOS and turn off Secure Boot.

Did you try this?
