I just replaced the Motherboard with a new Abit KV7-V Socket A Motherboard and a new CPU chip (AMD Athlon XP 2900+ CPU 400FSB) Also at the time I replace the memory with a Ultra 512MB PC3200 DDR 400MHz Cl3. However now I can not get the computer to run windows. I had a problem before and they told me to I needed to replace the motherboard so I figure i better go with a good upgrade. BEFORE I would not even get a screen when I powered up. The fans would come on but nothing on the monitor. Well the problem is taken care of now but now windows is not working. I am sure that it is a Bios issue but I do not know what to do. I have a AVI All-in-Wonder Radeon 9000 PRO video Card which was on the computer before but seems to be working fine. Also the psu is a 350w so it should be enough watts. This is what the screen is saying right now:
