Hi I have a problem with my bios update in my old pc.,

whenever I boot my pc I have to change the date and time in bios, it won't boot directly to OS., I have change my RTC cell(Cmos battery) to new one, according to advice of a friend., but still it does not make any change., It is Pentium 4 500gb HDD Sata with 2gb ram Can anyone help me with this??
Thanks
Sam
