Hello . After my PSU got burned I put it another PSU but my Asus F2A55M-LK2 shows green power led but won't start anymore . When I installed the PSU after a couple of hours started on it's own without me pushing anything . Today I made it starting it for a few times by just pushing power button booted succesfully but functioning just for a few minutes then stoping . Now won't start at all . What should I do to find out what the damage is ?
