So I got myself a second pc. With that PC I have tested the power supply and it didn't change anything on mine while running perfectly on the otherone. Should I get myself a new motherboard and if that problem persists a new cpu since I now do believe that one of those aren't Working anymore. Is there any possibillity that the cpu or motherboard just gave up while making it seem to be working (fans spinning, lights on the moba turns on). The case is dusty in the inside.
