I was in a hurry to leave and while playing CS:S I flicked the power switch on the back of my computer, when I got home my computer wouldn't boot. I figured out a fix by turning the switch off then turning the power on (Lights come on for about 2 seconds then it goes off) then flicking the switch back on then powering up. But now it won't even turn on after that and I can't figure out what's wrong, any help?
