Make sure you installed the CMOS battery correctly. If the battery is installed upside down, obviously it's not going to work right.

If the CMOS battery is installed correctly, and you were already having this issue BEFORE you installed the CMOS battery, and still have it afterwards, then I'd suggest that you have a motherboard problem that is almost certainly not correctable or repairable, possible a failure of the BIOS ROM or system timer, or the power wiring between the CMOS battery and the BIOS ROM. Having a main battery installed should make no difference so long as the unit has a new CMOS battery. Also, make sure you've SET the correct time in the bios AND reset the correct time and time zone in Windows.

Yes the CMOS battery is installed correctly , after updating the bios I start having the time problem and windows very slow sometimes even if still fresh , and after replacing the CMOS now I have HDD problem too

That sounds to me like you have more than clock problems. I think you have a failing motherboard which would not be surprising in a unit that old. I'd start thinking about a newer model.

It might be worth running Seatools for Windows or DOS, or WD lifeguard tools to test the drive and make sure it isn't simply a failing drive as well.
