I've got an old Windows PC that's giving me a hard time—whenever I try to turn it on, it just won't boot up. I have to unplug it and plug it back in for it to even attempt to start. Plus, I keep getting a warning message that reads something like: "The current BIOS settings do not fully support the boot device. Press [F1] to enter the BIOS Setup." It also tells me to go to Advanced > Boot > CSM parameters to change some settings. I'm not too tech-savvy and would really appreciate any help on fixing this issue. By the way, if anyone needs more details about my setup to offer guidance, just let me know!

Make sure to boot in legacy mode; it might solve your problem!
Just out of curiosity, what brand and model is your PC? Knowing that might help us provide better suggestions! You can usually find this info on a sticker on the back of the unit.
You might want to consider switching to legacy BIOS instead of UEFI. Sometimes, older systems boot better that way, especially if your OS is outdated. The smart thing to do would be to follow the error message's advice, as it might lead to the fix you're looking for!
I appreciate the help, but can you make this a bit more straightforward for me?
It sounds like your CMOS battery might be dead. This battery helps keep BIOS settings when your computer is off. You could try replacing it to see if that helps with booting issues. It's usually a simple fix for BIOS-related problems!
How do I go about changing the battery?
Sure! It's an ASUS All-In-One PC, model ET23221I.
