This year for career day I had chosen to shadow an employee at a computer repair shop on San Marcos boulevard. The shop repairs, builds and sells computers for quite a low amount, though they do traditionally work on much older hardware, given that computer technology has made so many advancements from 2000 to 2017. On career day, I had expected to be assembling systems comprised of brand new, and more recent parts, though a majority of my day was working with much older hardware, about 16 years old, and most of the systems were ones that had come in before. to be repaired, but they hadn't lasted long enough. One particularly interesting case was a computer that was running windows XP. the computer had begun to distort the display and block out certain parts. when we had gotten the system open we had found that several capacitors on the Graphics Processing Unit had burst, creating instabilities in the system. soon after discovering one of the main problems we had replaced the GPU and had tried to boot it up, but it wouldn't remain stable. Eventually we had found a GPU that worked with the very old system and we had tried to turn it on a final time, Showing that it was finally going to work. After that my mentor had me move on to three other computers, one marked for disassembly, and the other two marked down too be fixed and brought back into working order. The salvage job was rather easy, though the computer case was fairly difficult to work with. The first replacement job I had was to troubleshoot
