“PC won’t turn on? Swap the Motherboard, CPU, Case, Power Supply, and CPU cooler (so only really keeping the SSD and RAM)!” This mentality doesn’t teach newer generation of PC enthusiasts much and gives the impression that taking care of issues themselves is costly.
Well it can be costly, yes. People, wrongly, state that building a PC is like Lego for adults or some such nonsense while completely ignoring the miserable reality of the software running on the machine or that a percentage of hardware released out into the wild is expected to fail by the manufacturer. One’s Lego model doesn’t suddenly stop working one day.
I’ve been using/building PC’s for almost 3 decades now and I’d not wish a person to have to just blinding build, operate, and/or repair a PC (or Mac) without knowing someone who could help them who is literally near by or a phone call away. It’s just not realistic for most of society. So I see little profitability in going through all of the steps and commitment one has to make to run a successful, profitable YouTube channel on the subject.
Hell, even a YouTube series on how to properly search for information (or how to phrase one’s question about their problem) on Google and Reddit would be better, in my opinion, than a rando doing “PC repair basics!” on YouTube alone. But even the latter is the most I would expect. Beyond that it seems to go right to KrisFix or Louis Rossman, doesn’t it?
Besides, all one can really rely on is generic observation, testing (regardless of method), repair attempt, and confirmation that the problem is gone like any trade school teaches for any repair trade/profession.
There is just no tablet of commandments for PC repair because each person has different knowledge and tools/parts available to them. This also is completely ignoring the cost of tools used to do a repair/build. I know everyone is like "you just need a Phillips screw driver!" (to strawman like you have in the quote), most of the time, but that’s not what my work bench looks like after I finish a build or do a repair sometimes. A screwdriver is sometimes a few hundred short of the tools and other things I end up using be they pen magnets, zip ties, a Dremel, or a even a known-good PSU (with known good cables!).
If that is what you’re looking for then I’d recommend watching multiple PC build videos, but not some few-minute montage ones. Paul’s Hardware, for example, will, from time to time, do something along these lines where he goes right into installing the OS. Hardware Unboxed sometimes and even Optimum Tech will occasionally do this, too. But in the case of the latter even he can get a little too montage’y at times. These videos usually provide discussion into why parts were chosen, etc. That’s about as deep-dive as a normal user needs and should give them the foundation they need for using observation to help diagnose things by elimination and/or isolation.
Anything more detailed is what long form reviews and architecture explainers are for when a processor or graphics card comes out. But after that is usually to the Reddit-mines to look for anybody talking about specific problems with a specific thing and/or it’s firmware/software at a given time, unfortunately. Too many devices from too many manufacturers with too many things that can individually go wrong.
There’s a chance you may already be seeing/reading these things you seek, but aren’t quite recognizing them for what they are. Of course like car repair (and the modification/performance scene), though, professionalism will vary.
