I am new here and with computers and I would like some advice please. I am going to school for IT and technician but I havent had a whole lot of experience. I had a guy bring me 3 computers, one he said may have got struck by lightening. He wants to know if I can build him one computer. None of the power supplies work because when I plug them in, the fans dont turn. I dont even know what parts go to what computer because he had some of each PC taken apart already. What should I do? Build it outside the case to see whats what? Should I even take on a job like this? I want the hands on experience but it seems all I get are these crap jobs. What would you guys do?
