LOL sorry. Let me better explain, the new computer might not recognize your graphic card. SO, you plug directly into the MOBO DVI slot, boot up. ----->
Install all your MOBO drivers then install all your Graphic card drivers. After you have done that, you need to go into bios, you need to change your main video source to your graphics card. After that, Save and restart, then shut down and switch monitor cables to your graphics card and boot up. Let me know ASAP!
