ATI Radeon 2400 stoped working

I have an 12 year old computer and my graphic card stoped working yeasterday. I tried to instal AMD catalyst control center and it doesn't detect the graphic card, It only uses the onboard graphic.

Can someone please help me?

It used to work before but suddenly my BIOS started using the onboard graphic and now it doesn't recognize the graphics card.
I tried in another computer and the graphics card worked fine,
Already thought it was from my PCIe slot and i tried another graphic card and it worked.

This is what the log at the end of the instalation says:
