Just tried to upgrade my GPU and PSU, now my computer won't turn on. I think I have everything plugged in correctly. The motherboard has a light that is coming on when I turn on the i/o switch but the power button doesnt light up and nothing happens when I try it.

I have a 2010 Dell Inspirion 580 with an 3.2 i5 and have upgraded the Nvidia GT 220 to a GTX 760 and the power unit to a Corsair CX750M.

Any help here would be awesome, I thought I could handle this but I have no idea how to troubleshoot
