If u dont have another PS.. Just Unplug roms n all other hards... Only keep ur Bootable hardrive where u have the OS... If you have the external VGA unplug & swich to Onboard VGA.. Then power up & see.. The problem is with the PSU... You can replace it with a good PSU.. but buy something like @ lease 500W... Otherwise ull get the same problem...
. also there is a abnormal sound from HDD
