I just put together my first build; ASUS A7V880 MB,MSI RX9250 128 MB DDR video CARD,AMD Athlon XP 2.17 CPU,20 GB used hard drive,16x DVD ROM,128 MB Corsair Extreme memory(1 slot).
Everything came on after;fans,cpu,lights,and I got the motherboard set up screen on my MONITOR. It said to hit delete to set up. I did that,and nothing happened.
Then I went back in the case,tried to figure out if I hooked something up wrong,rearranged the ribbons,power leads,then I got a blank screen with only a orange light lit. Now that's all I get.
I'm hoping  that I didn't short out anything,can someone who's an experienced builder,PLEASE help me. Thanks.Which operating system are you thinking of using?

When you hit delete was the keyboard powered up?

Could you toggle the NUM light on/off?Yes the keyboard was powered up.
There is already windows me(i think)installed on the hd.
I could not get the num lock to TURN off.It sounds like you were going great until you went back and rearranged the leads.
Put them back & start again.
