I own the ASUS P5Q SE/R mobo and the Q9550 CPU. Something weird happens when I manually define FSB speed, PCI, RAM etc in BIOS. Let's say everything is left at AUTO in the BIOS. Then I turn off all power to the pc on the wall socket. The whole system is now without any power at all. Then I turn on the power again and press the on switch on the pc. The PC turns on without any issues. However - if I do the above and have defined FSB Speeds, PCI, RAM etc. manually in the BIOS someting weird happens when I turn on the PC. After total power cutoff on the wall socket I then turn on the wall socket again and press the on switch on the pc. The computer then turns on for 1 second and then turns off for 1 second and then it turns on for real and POST. Can anoyone explain to me if that is normal for an ASUS mobo or....?
