    Are you sure the wall outlet still has power? Did you try to plug a lamp into the outlet to check for power? If your PSU isn't plugged directly into a wall outlet then please make that happens.

    Often a computer can break and still remain functional until power is removed. Once the power is gone the broken circuit can/will no longer function. The power button on your computer case could be broken or simply have a lose wire. All the power button does is briefly short the connection. When you push the power button the motherboard will sense the short and turn on. You can check the power button's connection by briefly shorting the two wires that connect the power button to the motherboard at the header.
