Antec SmartPower 2.0 350w power supply
ASUS A8N-SLI Premium motherboard
Both of these components were working fine until yesterday, now the computer is unresponsive to the power button. With the power cable plugged in, and the switch on the power supply on, the small green LED on the motherboard is illuminated, but there is no other response from the system. The powersupply fan does not spin, and I cannot get the computer to power on.
How can I determine what the problem is? I do not have another power supply or motherboard to test with.
Does this sound like a powersupply problem or motherboard problem?
Your Powersupply fan not spinning points to a Power problem.
Also, if you unplug the power supply and plug it back in..some power supply fans spin for just a sec. indication that powersupply is working.
just my 2 cents.
