Difficulties in the work of computer engineer

You can think that the job of computer engineer is easy. Doesn’t boot? Unplug all useless and check again. If works - unplugged device is a key, if not - better buy new computer. Only two ways of solving problem.

This technics work only if computer doesn’t boot. But what if it boots? What’s next? How can you trace bugs? This time you would use your head and experience, if you have. No experience? Ask specialists in this case. But we’re ubnormal users. Imagine that computer specalist is far away. For example, you’re on the desert island. How you would change details is another question. However you don’t have access to any human resource. Where would you ask? Of course internet! So this post is a question to all of you.

Few months backward. I completed company’s order for 13 computers. Reminder: twelve simple computers and one power computer for chief of the company. Everything was fine, computers worked their money, I earned good reputation and some money. But last week boss of this company has called me. He asked me to check his computer, because computer didn’t work right. When I came, first I asked him what’s wrong (remember?). He said computer rebooted several times. I checked all cables and than powered on system. All seemed normal, but I had to believe him because he was smart boss. My opinion was that memory had errors. I changed memory and went away. Next day he called me and said bug remained. I came again and this time I changed PSU. But it didn’t help. On a next day I received new call from boss. Detail, which was broken as for me, was motherboard. I switched it. Computer worked fine for several days and then I received new call. This time I was really annoyed. What it could be? I won’t explain all what I switched, but I can tell you what is left untouched. Processor and hard disk were the same all the time. Now I don’t have any access to this computer. But I still want to solve this problem. Has anybody met this? How have you solved this problem? I’m desperate now. This is my first unsolved problem.
