I press the power button, the fans start up, everything's going, but no beeps, no error messages, not even a signal sent to the monitor. I just bought a brand new Soyo SY-K7VTA Pro V1.0 motherboard with an AMD Athlon XP 2400 processor, and i put in my old 256 MB mWave memory, a network card, and my nVidia GeForce 2 MX video card. My hard drive is a Maxtor 7200rpm 20 GB. It has everything from my old computer still on it (OS and all). After nothing happened with this setup, I took out all my cards, memory, etc. I also disconnected all the IDE cables and all the power cables, excpet for the power to the motherboard. Still nothing. I also tried different combinations of cards and IDE and memory in hopes of isolating the problem. But still nothing. Any suggestions?
