Predator G3620, stuck in Acer logo, and I can neither access BIOS nor the Windows Boot Manager

My Acer Predator G3620 from 2013 (upgraded from Windows 8 to Windows 10) suddenly, from early April, will start no more. As soon as the Acer logo shows on the screen, the PC stalls – and not even one single beep signal can be heard. Now I can neither access BIOS nor the Windows Boot Manager – no text at all at the bottom of the screen.

I need to attach a USB installation disk, start again and then (most often) I can change the boot order in BIOS to boot from there. After that and luckily just after1 short beep signal it works.

I suspect troubles with my Windows Boot Manager. Following many descriptions, I have tried correcting it and then I updated my Windows 10 from an USB installation key – nothing with success. Unfortunately, in this version and build of Windows 10, I am not allowed to alter all the boot elements.

I do not see any another error messages and I cannot really interpret the content of the system’s log. Could it be HW errors, CMOS battery etc.? How can I check for the location and cause of the error?

Environment:
Windows 10 Home; version 22H2; build 19045.4291 (originated with Windows 8).
64-bit system, x64-based processor: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz .

    I have tried many things including changing the CMOS battery - but unfortunately with no success. Howeverm I found out that in BIOS I should change the "Legacy USB support" to "Disabled".

    Now everything runs smoothly once again, and as I have no old USB devices, then I do not really need the "Legacy USB support" to be "Enabled".

    First thing to look at for a system of this age is the CMOS battery. If it has failed then you can get some really weird symptoms. at just about 11 years old it would be usual for the battery to have gone dead. It's an easy replacement, and pretty cheap. Once you have a new one in there, boot to the BIOS and have it reset to factory, then save and exit. Things should come up normally from there.
