I have a BIOSTAR P4M900-M7 SE Motherboard. The original CPU was Intel Celeron 2GHz LGA 775. I have upgraded the CPU to Intel Pentium 4 3.8Ghz LGA 775. What should I change in the BIOS system in order to complete the upgrading.
Unless you're having problems, you shouldn't need to do anything in the BIOS. If you are, try resetting the BIOS (clearing the CMOS jumper or pulling the battery).
