I have an ASUS Sabertooth 990FX motherboard that is brand new and paired with an 8350. When I flip the power switch on my PSU the standby light comes on on the motherboard. But when I press DirectKey or try to turn on the PC with the case button, nothing happens. No fans spinning, no beeps, no hard drive spinning. I have taken out the video card, sound card, unplugged the USB cord, and tried only the CPU 8 pin connector. I have a Phenom II X4 965 that I can try when I get home. Nothing is working so far. Please help!! Thanks.
