PC Won't Boot, ACPI BIOS ERROR
My wife's PC won't boot, gets the attached message after about 3 or 4 minutes. I looked at the BIOS and didn't see anything suspicious. Once it also said ACPI BIOS ERROR in the message. I did notice the BIOS said it was last Sunday evening. Thinking the batter was bad I changed it and wondering if that cleared the BIOS because now it just gets a black screen and the monitor does not see an input. I tried a UBCD but it wouldn't boot to that. Everything I read about ACPI indicates troubleshooting from either the BIOS or Window and I cannot get to them.
It's an old MSI 970A-G43 motherboard, AMD FX-6300, SanDisk SSD, and 16 GIG DDR3.
Looking for any suggestions for next steps.
