    when i boot my computer everything runs but it does not display anything at all(monitor does work) and none of the usb plugins work, i have a brand new motherboard because my last one died. My keyboard lights up but when i press num lock or caps none of those lights light up. it doesnt make any beeping noises either

    POST failure. Check the new board has been installed properly, and all power connectors are connected securely (especially the 4 or 8-pin CPU power connector)

    Ive checked everything and i thought maybe it was because my psu has a 4 pin connector and the mb requires an 8 so i got the adapterno luck

    What PSU are you using, and what motherboard did you buy?

    Out of curiosity why the P7N SLI? I know it's already been purchased, but I'd like to make you aware that nforce chipsets are commonly unreliable.
