I'm upgrading from a Ryzen 7 2700X to a Ryzen 7 5800XT on an ASUS Prime X470-Pro, but I forgot to update the BIOS first. The old processor is stuck to its heatsink, and I'm worried that forcing it loose could damage the CPU or its pins. Is there a way to install the new processor and update the BIOS from a USB drive, or should I take the system to a professional?

To separate the old CPU from the heatsink, gently warm the heatsink with a hair dryer and then twist the heatsink sideways instead of pulling straight up. The dried thermal paste usually releases with warmth and gradual twisting. Protect the CPU from being dropped, and inspect every pin afterward under good lighting.
Don’t try to force the old processor into the socket while it’s still attached to the cooler. That can put leverage on the socket and pins. If a pin is only slightly out of alignment, it may be possible to straighten it very carefully with a fine tool, but a badly bent or broken pin is a good reason to use a repair shop. You could also ask a shop to update the BIOS with a compatible loaner CPU.
First check the motherboard’s supported CPU list and the BIOS version required for the 5800XT. If the board has USB BIOS FlashBack, you can update it with only a power supply and a correctly renamed BIOS file on a FAT32 USB drive. Follow the exact instructions in the manual. If it does not have FlashBack, you’ll generally need a supported older CPU installed to boot into the BIOS updater.

The ASUS Prime X470-Pro may not support CPU-less FlashBack, so verify the rear-panel buttons and manual rather than assuming a USB update will work.
