Ok. I'm new here and this is the thread to my "noob" post. https://www.techspot.com/vb/showthread.php?p=338578#post338578 This is my problem. I put the new machine together. I've got a RS400-A motherboard with an Intel Celeron D 775 pin CPU. It has 512 Mb DDR2 533Mhz Memory and 80Gb HD. Dual Layer DVD writer. I put it all together and I have no system beeps and no display on the monitor. I checked all the jumpers, and even tried resetting the bios using the jumper suggestion in the little book that came with it and then tried pulling the battery on the board. No luck. I haven't been able to find anything regarding this problem on the manufacturers website so I decided to try my luck here. Any help with this problem would be appreciated. I can give more info, but don't really know what y'all would need to help out. Thanks.
