@Shayan2, welcome to the forum.

 

It sounds like you have a failing CMOS battery.  Here is the Illustrated Parts and Service Map for the computer.  On Page 2 is a diagram of the motherboard.  The CMOS Battery is Item XBT1 (Real-time clock battery).  I believe that it is a CR2032.  You can make certain when you open the case.
