So i got used PSU from my friend and i wanted to switch it with my old because it was loud. So i normally unplugged the old psu and plugged the new one in. But when i was connecting power cable to it. Little spark flew from the cable to the PSU and burnt it down. Nothing else started smoking . So i think that other components are alright.
So i connected back my old PSU. A little light on the ethernet connector light up when i connected in ethernet cable so there is electricity going thru my motherboard. But when i press power button NOTHING happens. What do you think is it bad PSU or CPU or can i repair it somehow ??
I have Lenovo ideacentre h535
with different PSU
EDIT: PC did not turned on even when i first connected the new PSU so then i wanted to unplug it and plug it back in and in that moment it burnt down. So the problem probably is not that CPU or motherboard is burned.
UPDATE:I started PSU on its own (http://www.instructables.com/id/How-to-power-up-an-ATX-Power-Supply-without-a-PC/) and then connected everything back. And when i press power button PSU starts and main case fan starts spinng. But thats all what is happening. CPU fan doesnt move neither does GPU fan. And screen is black.
UPDATE 2: PSU does not start using power button. But it works if i start it without a PC as i wrote before. So i think that PSU good. And that i will need to replace a motherboard. Or can there be anything messed up ??
