Windows 10: Updating Computer's BIOS to UEFI, older computer

Good afternoon,Bare with me, there is a reason for the background info at the start....I recently upgraded my graphics card to a GTX 1060 3GB. Now when i boot up the computer, it beeps every 30 seconds, but after about 5 minutes it boots on and i have full access and the graphics for various games are now much better. My solution so far has been not to shut down unless required but I'm also looking for potential solutions. This has lead me to looking in the BIOS menu. Of course i cant access the bios when booting now since installing the gpu and had to reinstall the old one to look around not

Are todays computers safer to update BIOS?

I was servicing a new Dell Win10 computer the other day and in the new notification list it was recommended to update the BIOS with a link to do so. I would have done so but over the years I've seen complaints about BIOS update problems sometimes even bricking a computer. Are todays computers safer to update BIOS? If the owner had a system image backup, would it be ok to do that BIOS update?
--- I sent the owner to Staples because that's where she bought the computer and it was under warranty.
