***There may be a problem with the memory module. It is recommended to replace the memory module. If the cooling fan doesn't turn, it may be too dusty. You need to clean up the dust and then wipe the memory module with an eraser. If the situation is still the same, it is likely that the power adaptor does not work, or the motherboard may have been accidentally dropped and cannot be started.***
