I take it you are asking how to get into bios.
Restart your computer and watch the post information - the messages in white on black before you get into windows. It will say something like, "To enter setup, press "x" where "x" will be either the Delete key of one of the F keys. That will take you into bios. Once in bios you will see different tabs for different functions. Some of the functions allow you to change things like the time and date, the boot order of the drives, whether or not you want the computer to search for a floppy drive or skip that search. whether or not you want the computer to do a "Quick boot" or a full post up with logo, etc. Some tabs may not present options to change anything but just report information like temperatures and voltages. In an enthusiast level aftermarket motherboard will have many more tabs with options to change the things I mentioned in my original post and many other things that affect the performance of the computer. Once in bios, look for those things I listed there.
If you want, you can take a digital camera picture of your bios and its sections and upload them with your post and we will see what we an spot that might be helpful.
