If your motherboard keeps losing its' clock settings and other BIOS options the first thing to do is change your CMOS battery, of course. However if this doesn't cure it, one of two things is wrong: 1. You have a CMOS virus 2. Ths Moboard is faulty. Before throwing your motherboard away, make sure you are not infected by a virus such as CMOS or CMOSDeath. A good antivirus program should detect this. For more information on CMOS virus try a Google search or one of the Antivirus sites eg Panda.
