I just got an old desktop PC and when I turn it on, it shows me this:

After a bit of a weird startup...

But it offers me to press F1 or F2, but no key on the keyboard works. Yet the keyboard seems to be detected. I don't know how to fix this problem...

Thanks in advance!

Hello,

Probably the CMOS battery is dead; on the motherboard, it's often a CR2032 found in supermarkets.

There you go, that's the first thing to check.

CR2030 > CR2032 (Correction by moderation)

You can measure them with a DC voltmeter (DC Volt)

It should be 3.2V for a new one, and below 2.8V is not as good.

Otherwise, if the battery is good, you need to reconfigure your BIOS if you press F1 or F2 to restore the default values.

I would suggest entering Setup (BIOS) with F1 to get familiar with it a bit, and change what is necessary to get the system working again.

Reset to default values to start, restart while saving (Save & Exit), then come back and choose the boot priority order in the BOOT section.

If it doesn't work,

Do a Clear CMOS before reconfiguring your BIOS.

You can read the manual, it should be explained there.

Or

Disconnect the power
Remove the CR2032 battery
Short-circuit the two pins for 10 seconds; sometimes there's a jumper to move, or it's often labeled CLR_CMOS.
Short-circuiting the + and - poles of the battery socket can also have the same effect.

Okay, yeah I'll try the second option tomorrow because the keyboard isn't working strangely...

I'll keep you updated.

And thanks again for your responsiveness!!

Hello,

Indeed, a typo happens.
