Well, do it all one piece at a time, so if something doesn't work, you will know what is causing the problem...
You put the mobo in... Processor on mobob... heatsink on processor... Connect power button/restart button/any lights to mobo (can be done before the processor...
Then start it up to see if it turns on. There should be a green light on your mobo, and that is a good sign...
I haven't built in a while, so if this is wrong, then somebody can correct me... also... it is very late...
EDIT: you'll have to connect power supply to the fans/mobo, also... soo late... :amazed:
