I just built a new PC. Specs: Mobo - Asus P6TD Deluxe CPU - i7 930 PSU - Be Quiet! Dark Power Pro 850 RAM - Crucial Ballistix 6GB DDR3 Tripple Channel GPU - 8800GT (from my old machine, haven't got round to buying a new one yet) Sound - Asus Xonar DX Symptoms: I plug in the PC power, flick the switch at the back, the power and reset buttons light up on the mobo, press either the power button on the mobo or the front of the case (it's the same either way) the LED's in the fans and the RAM light up for much less than a second, then it just won't do anything until you completely power down the mobo (unplug the power and wait for the lights to turn off on the power and reset switch on the mobo, then plug back in). What I have tried to fix the problem: I have checked all the power connections to the mobo. They are correct and in fine. I have checked all the jumpers. They are all on normal. I have taken out the battery for a while. Then put it back in. What I think it might be (but I don't want it to be ): I have googled this and so far it says the PSU might be faulty or something. Any help is much appreciated.
Make sure that your motherboard is grounded properly. Is it sitting on all the little standoffs and screwed into the correct holes so that it's not touching the case? Make sure that the power switch is connected correctly to the motherboard too. Also go over all the connections again, you haven't missed the little 4 or 6 pin connection on the motherboard near the CPU?
