Hi! I have been troubleshooting and building PCs all my life and I find it very important to know the the internal core components of a PC and how they function that way when errors occur you can attempt to fix the problem.
Ex1: Lets say your BIOS identifies a problem with a RAM slot you would be able to know that your RAM slot is either shorted or there is a problem with the RAM stick you inserted.
Ex2: Now your monitor is flashing and turning colors randomly. You could make an inference that either your monitor is prongs are broken, your cable prongs could be bent, your cable might not be plugged in all the way, or your external or integrated GPU is toast.
Hope this might've showed you something
