I am using a IT7-Max2 board with a 2.4 Pentium 4 chip. All of a sudden, on\nbooting up it says the processor is 1.8 and operating at 100mhz whereas it\nshould be 133mhz. The process stops with a message that there is a mismatch\nin the CPU and it should be corrected using the Setup screen. The\nmotherboard has error light showing 7F.\n\nThe solution should be simple: press "Del", get to the setup screen and\nchange the CPU data through the menu. Unfortunately, it is not possible to\nmove up and down the menus. The machine is stuck.\n\nInstead of pressing "Del" one can choose "F1" to continue. Then the computer\nproceeds to boot up and works under XP, albeit a little slowly.\n\nI have tried clearing the CMOS by changing the jumpers, and reinstalling the\nBIOS. Neither makes any difference, and the latter fails saying the update\nprogram does not match the BIOS even though it does match.\n\nAny suggestions on how to solve this problem much appreciated.\n\nBest regards.
