Intex power supply < This very well could be your issue , they are horrible quality power supplies.

could there be another problem except power supply
because i had repaired my mobo twice because the ic of mobo was damaged

Yes could be a failed board , hard to tell the symptoms can be a few things.

Bad power supply can cause damage to the motherboard, and for such and old system you are better or replacing then repairing. You need to try motherboard and possibly power supply to see which is the cause of the issue, either may be it.
