• Disassemble the PSU and repair internal circuits

• Format the hard drive

• Replace the CPU

A PSU has been tested and delivers unstable voltage outputs. What is the best course of action?

• Adjust the voltage manually in BIOS

• Continue using it, as fluctuations are normal

• Ignore it if the computer is still running

• Replace the PSU immediately to prevent damage to other components

What is the purpose of creating a bootable USB drive?
