When I tried to turn on the board with nothing installed on it, just the power supply, it would turn on quickly then just shut off. I thought this was a protection thing for the motherboard since no cpu, memory, or video was installed at the time. With the CPU installed the board powers up and statys on, but no beeps or video. The current case has a powermax 500 watt psu. I have another case with a 300 watt power supply. I'll put it in that case and will see what happens. There is a computer show this weekend. I am so frustrated that I might buy another mobo, cpu, memory, and video and give that a try as well. Thanks for all of the suggesstions!!!
