Hi, recently my old computer got a virus

each time i tried to go play World of Wacraft my computer freezes and i have to turn off my computer

so ii put the current graphic card from my old one to this computer

and i installed the ATI graphic program, i have a radeon 2950

and i dont know why each time i plug my monitor in the graphic, my monitor is on but my screen is black

any suggestion?

When you start the computer, can you see the stuff? Or is it black the whole time?

Your computer might not be giving enough power to the card, driver conflicts, or its outputting the wrong signal.
