To make a long story short - get a new one.
This is more of hands-on repair BB, AFAIS. Are you willing and able to perform hands-on repairs?

thankyou for replay

yes sure i have a repiring shop and the vga card is for my customer if i rebulling the chip it be fixed or must change the chip

Well, in that case, rewind and start from the beginning.

What type of board do you have?
What is the board revision?
Post some close pictures of both sides of the board.
What POST code do you have with this card being a primary adapter?
Does it show up in the device manager when used as a secondary adapter?

So far it sounds like "Hello, I have an old spoTs car and it does not drive! Can I just reinstall the motor??"
