I bought a new ati radeon hd 3650 and have done everything to try and get it to work with my monitior. I upgraded the power supply and it is hooked to the card, i updated my bios and chip set, i uninstalled all my other graphics cards drivers and disabled it. when i have my new card pluged in the monitior will not work, but will work with my old one. right now the computer is running on a vga save and i cannot disable the onboard graphics and dont know if i want to in case this does not work help please.
