The reason why the machine cannot be started is nothing more than memory, graphics card, power supply and motherboard. Since the motherboard of your computer is good and the fan can rotate, it is memory and graphics card!First, clean them: remove the dust, remove all the parts, and thoroughly clean them!Check whether there is any sign of oxidation, and wipe it with rubber.Ensure good contact when inserting.Not good, just redo the system to see if it doesn't work. If it doesn't work, it's that the internal parts are broken. Go and repair them!
You still haven't explained clearly. Is the keyboard light on?The problem you are talking about seems to be that the main board is short circuited. Take down the video card and turn it on.
