Computer sometimes turn on but rarely. When it doesnt turn on nothing happens. Fans dont spin and no noise etc. I think it is probably a Power supply problem because I hear a buzzing noise from it when my computer cant turn on. When there is no buzzing noise my computer can turn on. Also I have test the power supply on another computer and it works prefectly but that computer is older so it needs less power to run.Its not motherboard problem i dont think because it can turn on sometimes and the motherboard runs fine when it does turn on.
