i just bought an ECS KT600 motherboard, they booted it up at the store, and when i got home and put it inot my comp nothing happened. My processor fan and CD-RW where the only thing's that got any power. It's an older tower, but has a new hard drive, CD-RW and floppy drive. I'm running a 1Gb AMD processor and 2 sticks of 128 Ram. What could the problem be?
