A few days ago the power went out for about 30 minutes, when the power came back on, my computer doesn't seem to power back up. there is a small LED on my motherboard which stays on when the power supply is connected, if I turn off the witch on the power supply for about 10 seconds, the LED will go out, if I turn it back on at that point, the LED comes back on, and if I hit the power, the fans on the power supply and CPU fan will come on for a split second. my power supply has blue LEDs in it too and they come on for a split second at that point also. after that, it won't do anything but the motherboard LED stays lit just like it previously did. I'm hoping that someone may have seen a similar issue previously as there are a large number of things that could cause my computer not to power up.
