New Motherboard Problem

[Machin3]

I just got the XFX 780i which replaced my EVGA 780i which i have to send back to the company because its broken, but anyway, I swapped motherboards and everytime I turn on my computer, I dont get any picture (which i dont understand why).

****Also****
I get a little red light underneath my cpu heatsink plug (which I also dont understand why)

Any thoughts?

Thanks

Not the answer but, did you know that Foxconn makes both EVGA and XFX motherboards?

When you changed them out did you make sure the standoffs were in the same places? It should say in the manual what the light stands for.

**Update** I figured out that every time I screw down my Heatsink, the computer start, but if I place the heatsink on the cpu w/o screwing it in, then everything works fine. What to do with that?
