How to Identify Failed Capacitor on Circuit Boards
This post will give a little bit of idea, how to identify a leaked / Bad capacitor that soldered on a circuit board by visual inspection. This might help you in checking capacitor problems on motherboards and other circuit boards.
The most common method of identifying a failed electrolytic capacitor is by visual inspection. Because we cant desolder all the capacitors and test it using multimeter right? So the below symptoms may be expected to inspect on the electrolytic capacitors within the board.

USB Types And Pin Diagrams
We may usually noted that some USB cable ports from motherboard have different pin outs. Connecting unsuitable cables to these types might cause short circuit the PC power supply. So here is the pin assignment of each type, USB2, USB3 & USB4 as headers. These headers are used to connect auxiliary devices to the main board. The headers are directional and will only allow USB cables to be connected in one direction. Checkout the Image below

35 Tips to Design a Reliable PCB
Printed circuit boards are essential to professionally design any electronic system. It is often happens that a circuit which functions well over a breadboard may not work properly when implemented on a PCB. This leads to complexity over circuit and system engineers need to be spend at least 2-3 days to rectify the problems.
