Ok, here's the deal. I picked up an AMD AthlonXP 2800 / motherboard combo for $100. I realized that my old RAM simms wouldn't work, so I went out and picked up some Kingston DDR SDRAM dimms, 2 @ 256mb each. When I tried installing everything, I double checked all the connections, tried to power up the computer, and it would not POST (Power on self test), instead, it would beep once every 2-3 seconds. Does anyone have any idea what could be the problem?
