I've had my computer for about 3 weeks now and nothing has gone wrong, but I got home tonight and it wont power on. No lights on the mobo, nothing. It was working fine 6 hours prior and I left and came back in that time so nothing was done to it. I tried plugging it into a different wall socket and flipping the power switch on and off and nothing is working. Please help this is my first computer that i've built and I have no idea where the problem might be.
