So how's your day been so far?
If you try to turn it on if you don't see any lights come on or hear fan or the HD start up then
1/ is the plug outlet supplying power ie is something else working from that plug?
2/ check the fuse in the PC power chord plug
3/ if no joy the power supply, supplying the motherboard needs to be checked with a multimeter.
When it rains it **** pours.
