Question about MSI K7N2 DELTA2-FSR NVIDIA nFORCE2 ULTRA 400 CHIPSET SERIAL ATA150 ATX FORM FACTOR 1xAGP(8X)/5xPCI/... Motherboard
My system will not start up. When I press the power switch, the CPU fan spins once and then nothing happens. After this, the system is completely unresponsive unless I turn the power supply off and back on again, then I can spin the CPU fan once more.
I have verified that I have a good power supply. I have removed all peripherals from my motherboard and only connected the 20-pin power and the 4-pin power to the motherboard. So there is only the power supply, motherboard, cpu, and the ram, nothing else. In this configuration, the "spin once" behavior occurs.
If I remove the 4-pin, the cpu fan will come on, but the system will not POST. I believe that this is probably the CPU, because the 4-pin supply powers the CPU. Is any way I can verify which component is bad without buying a new one of each, one at a time, and installing them?
Oh yeah, this first occurred when my old power supply died (I could smell electrical death in the guts). Before my old power supply crapped out, the system ran fine, and it had the 20-pin and 4-pin connected.
It is more than likely that when your old power supply died a death, it damaged some components on the motherboard. Replace the Motherboard and chip, and you should be back in business. You can pick up some good value bundles to save money on buying the parts seperately. The power supply working again after turning off and on, is because there is a little trip in the power supply that triggers when it detects a fault. Powering down resets that trip allowing it to try and work again.
