OK I have the computer up and running, no OS installed yet. The 1st try I got into the bios and set the date/time and other stuff I wanted. I pressed F10 to save and rebooted. It would not reboot all all I got was three beeps, so I shut off the main power switch and turned it back on it posted and I had to go back into the bios and redo everything. this happened 3 times one time I got 4 beeps. Then I jiggled the top gfx card hit the reset and it booted to the no os disk installed. I reset it and powered down four or five times and now its goes to the no os disk installed, no problem that is what its suppose to do. My question is why do you think I had to redo the bios settings in the begining but now it seems fine. I am going to get a new mainboard battery just in case. Would a bad connection from one of the gfx cards cause it to loose the bios settings? It does not seem possible to me. The case has plastic retainers to hold the cards in but I am going to screw them to the tower. As they seem a little wobbley to me. Again thanks!!!!!
