alright, i have a serious problem

so i came home yesterday and my computer was turned off, i had left it on when i left - i pressed the power button, nothing worked. no lights, nothing came on. so i assumed that my power supply died and i needed to replace it.

i had an 800 watt xion supernova power supply, and i went out and bought a Kingwin 1220 watt Mach1 power supply.

my problem is, i wanted to see the computer at least turn on to make sure that it was the problem - i've plugged up the 20 + 4 pin connector to the motherboard and a blue plugin (not quite sure what it's called, there are two of them and i can only find one to connect), i assume it's for backwards compaibility to the motherboard. though if i'm wrong, please correct me.

i've also checked the cpu + socket - there are no burns or anything, and it was kept cool.

my motherboard is a p7n sli ms-7380 nvidia nforce 750i sli

please, help.
