PC won't Turn on after Vt-x enabled in Bios

[awalon]

Today I upgraded Asus b560m plus bios, and all went well, after logged in Windows I noticed on task manager that Virtualization is Disabled and Hyper-v says Supported. So, first I revisited Windows Features panel to make sure that Hyper-v is not enabled which might have caused Virtualization to get disabled. But that was not the case, hyperv was unchecked also the other Hypervisor platforms, I always use Vt-x so I know how things shou be. So, next I restart pc to enable Vt-x in bios, and after saving changes Pc would normally shut down once but then it won't start anymore, it just gives a short signal as it powering on but doesn't proceeds further, it remains powered off.

I removed cmos battery, and then later PC booted into bios with default settings, logged into windows, and still vt-x disabled ofcourse, so i went back to bios again to enable, and same thing ahppens, as normally PC wud shut down after saving bios changes, but then wont power on , i also downgraded bios version to its rpevious version, but still no changes, i appreciate if anyone knows a solution and willing to help, thank you.

i think i fixed it thank God

Removed both hard disks/SSD's, and re-flashed BIOS again with usb, without any hard disk connected, believe it or not it flashed so fast comparing when i did with hard disk's connected to Moherboard.

after the bios flash was completed, normally pc will shut down and power on itself again into bios, so i changed bios settings like turned vt-x on, and tpm to firmware, saved chanegs and again pc will shut down and restart to bios, thne i turned pc off via power button on PC, and connected hard drives, turned PC on and all things are working now and bios changes are effective.

i hope this helps someone else too.

The PC's bios is not saved. After I changed the PC's bios and gave save and exit, the PC restarted and the PC runs fine again. I shut down the pc and unplugged it and after 5 minutes I plugged it back in and turned on the pc and then the pc turned on and then the pc turned off and the pc restarted. But nothing is saved in my pc's bios. Someone who knows how to give me a solution to this. A big help

You must consult with the system/motherboard manufacturer regarding issues with their bios.
