Hi! In my room stands a nice looking pc. One problem. It's old, like 8 years or even more. Unfortunately it doesn't work anymore. Now I tried to fix it, rewiring everything and cleaning a bit up (dust). But still, it doesn't work, I think one or more components are defect and I am trying to figure which, but I just can't. So, is there anyway I can know which component it defect and doesn't work anymore, so maybe I can replace it?
