I just recently bought a used emachines computer, and it was having problems. It has an AMD Athlon XP 2800+, 512K L2 Cache, 333MHz FSB. It had the original MOBO in it, and I just replaced that with an ASUS A7V8X-MX SE. The original MOBO was bad, because the power supply and fans would come on automatically when plugged in, but nothing would work. Now that I replaced the MOBO, everything comes on and runs, but I am getting no picture on the monitor. I tried replacing and reseating the RAM, replaced the battery, used the onboard video card, and tried using the AGP 8x GeForce FX5500 256MB I just bought. I have pretty much tried everything I can think of, except for replacing the CPU, which I really hope I don't have to do. Does anyone have any recommendations? I would greatly appreciate it. Thanks.
