I hit the problem right now. Just an hour ago my new rig still fine. I running the Prime95 and the suddently the power off (all the socket in the house auto turn off). So I tried to check every wires in my rig it seem to be fine and I turn on again, its still the same turn off all the socket in my house, then I tried to pull out the 24pins atx on the board and result still the same. There is a sound likr "bang" behind the PSU so its mean the PSU have problem? because I don't ahve anything plug in to the PSU right now. What should I do, please any idea?
