Remove/disable "it is now safe to turn off you computer "

Hello (sorry if this isn't the right Reddit, but I think someone could help me here).

I built an old PC with a SuperPower SP-6XS motherboard and a P3 500MHz processor. I installed Win98 SE, and I also tested it with Windows 2000. Once the OS was installed, when I tried to shut down the PC via "start-shutdown," I got the "It's now safe to turn off your computer" screen. The only way I can actually turn it off is via the switch on the power supply itself (I tested it with two power supplies, both from 2002-2005).

If I press and hold the On/Off button on the case, it doesn't respond either...

On another PC from roughly the same era (Packard Bell Platinum 7502, also with a Slot 1 CPU), I never got this type of message when shutting down the PC. I saw online that ACPI had to be enabled in the BIOS, which is the case, but that doesn't change anything.

Is this motherboard too old to support Windows shutdown? If anyone can help me, thank you very much!

Thank you for your help, it works well now!
probably the BIOS was reset and ACPI was not originally enabled?! In any case it's done and works as it should

You need ACPI fully enabled for this. In many cases if it’s not enabled in bios when you install windows you will have to reinstall to enable it

Yeah but it looks like it is activated.
I didn't pay attention before the installation of Win98 if it was enabled or not... so should I format and reinstall win98 now that I'm sure it is enabled ?
