These days, when booting, there is a BIOS checksum error, Load default. Later found that CMOS was set to default, which has never happened before. Is it a virus or the CMOS battery is dead? The machine was bought in 2001... (never changed the battery)

That must be because the battery is dead

Okay, if it occurs frequently, then replace the battery...

Just reset it to the default settings.

It's okay. Observe the BIOS after loading default. If it's normal, maybe your original BIOS configuration was wrong. If not normal, replace the battery. If still not normal, take it to a professional board and card test to find the problem and fix it. If none of the above processes work, go home and find the invoice to see if it's still within the warranty period, then get it repaired.
