Troubleshooting is the part and parcel of owning a PC, and with modern computers, you just don’t know when you’ll be made to put that hat on. Maybe you were tinkering with the BIOS to squeeze a little extra performance, or maybe you were just trying to boot into your system on a regular Tuesday. The problem is that more often than not, the problem won’t explicitly announce itself or detail the root cause, and you will be made to make educated guesses at every turn.
