How to set my time permanently if it shows cmos setting wrong error.

First try to change your motherboard's bios battery.
After you change the battery you should go through the setup&save process - during this, you must make sure that all hardware such as hard drives, CPU, RAM etc have the appropriate settings selected (in some cases AUTO is a good selection). Now if the battery's good and there is no hardware problem, your computer should start without that error message. If the message is displayed after a battery change and a re-initialization of the BIOS Settings, you have a hardware problem of some sort that the microcontroller can't resolve - in this case you should start with only the essentials and add one item at a time until you get back to that message.

Essentials are:
1. MB&CPU,
2. One stick of RAM,
3. Video Adapter (expansion card or built-in),
4. Keyboard, and
5. NOTHING ELSE.
