Yesterday I opened my machine to dust and clean it. Was extra careful with it. After re-assembling it and booting it, I got a "cpu fan error sceeen". So I tried moving the CPU fan around, getting it to a new position, and now I'm not getting any signal input from my computer at all. I've already tried moving almost every piece around, unplugging all the unnecessary stuff, but still no result. Would appreciate some help with this as it's the weekend, aka my only moment of rest of the week.

    Unplug everything except CPU, CPU fan and RAM, put the computer on the table outside of the case, plug the display into the internal GPU and start it by shorting the two power button pins with your screwdriver. If it starts, start plugging in components one after another to see what causes it to fail

      I did that. Even the bare motherboard+cpu & fan + ram won't give me any output display. Looks like the motherboard is damaged, which is weird because it displays all the leds and the fans spin. Any way i can diagnose this further, e.g with a multimeter?
