Question: I am getting an error message that ratio on the CPU has change every time I boot up my computer? 

Answer: It's your mother board battery that is out. with your CPU ratio your date and time will also be reset to 12:00:00 january 01, 2001. You will have to change your mother board battery. if u don't then also u can work. but for the error message to stop it, form ur BIOS setup choose "Halt On: No Errors".\n\nT.C.
