Used to be beyond mine, but 25 years ago I had to learn. I had bought my first PC, after starting as a Respiratory Therapist and it wasn't assembled correctly. They had used two different kinds of memory so it was throwing random errors. I had previous experience with Apple II, IIc and Atari computers (yeah they built some) but limited PC. I learned a lot from that computer and also learned to always build my own, if I'm doing a desktop. Stuck to that path ever since. It's physically getting harder to work on them with my arthritis, but I'm not out of the game yet.That's beyond my computer abilities.
