Hey James!
Its awesome to see that you basically have that solid experience when it comes to repairing hardware for that long, it’s astounding if anything. I am still early in my journey when it comes to IT and still figuring out what exactly field i would like to pursue. I’ve found that tinkering with hardware and figuring out what works with what and so forth and it’s becoming like a bug that instantly bites and could never go back! In regards to troubleshooting, good input on what exactly you do and how to go about it.
