Sorry for double post but I may have messed up my build.
So I put in the CPU, no problem. But I did have a little trouble with the heatsink. Then I installed the memory, no problem. I trying to POST outside of the case to see if anything is wrong and I guess there is. I plug in all the front panel connectors. Then when I press the power button, the fan turns on for just a second and then turns off. Any help?
