I installed the CT-479 Kit with the M750 CPU on the P4P800 SE. No POST. The BIOS is 1008, which is correct per Asus website. I did a clear RTC, Reseated PC2700 Memory, Checked all connections. No POST. I put everything back the way it was, No Issues, just like it was before. I guess I will try again, but I "got a bad feeling" about this project.
