Also, you will save some money honestly if you go for upgrading your personal computer. You should turn off your PC; unplug it from the wall; and disconnect the mouse, keyboard, monitor, printer, and any other external cables (such as USB). Then, what you are supposed to do is that you should remove the PC’s cover, and carefully look at what you need to remove or disconnect to reach the motherboard.
In some cases, you’ll have to remove a hard drive or other hardware to get to the motherboard.
