Pretty good advice. Though, he should be using an anti-static wristsrap when working inside the computer, and placing the motherboard on a anti-static mat instead of the table since Motherboards can be damage by static if the table has static. Plus, computer parts contain lead and other toxic metals which are not good if it contaminates your food, or drinks. I like his Power Supply tester that he got for 20 dollars. He also talks about testing RAM, CPU, and taking out all the expansion cards which is good advice. The best advice is testing the motherboard outside of the computer case.
