I have a desktop PC which is mostly used by my younger brother as I am used to my lappy only. Last night he opened the case and tried to clean the parts that had loads of dust on it. After cleaning and all, he placed everything properly and after that the computer will not start.
When checked inside the cabinet with machine ON, it shows that PSU is ON, CPU fan running but there is no power to the HDD and no LEDs glowing and therefore no starting of the PC. So that means only the motherboard is not ON.
Is it that the motherboard is short circuited some where? What can we do?
