ok gigabyte just RMAed back my motherboard yesterday and i tested it before putting all things together... i put one ram stick and the video card and it started good... then when i put it in the case with all the drives and the other memory stick and another cpu heat sink(bigger heavier) it did not want to POST.. and the fan of the CPU does not want to run for 30 seconds and also when i press on this thing stays on for about 30 seconds then it goes off and then it goes on again and i have to wait 5 seconds for the cpu fan to run...
