I inherited an eMachines W2247 (AM37 mobo) because of a "blank display" problem, and hoped that I could install a video card. How do I disable the onboard video? Is there a jumper on the mobo (I can't see one), or do I have to disable the onboard video in the BIOS? Of course, without a display, I can't access the BIOS. I visited eMachines web site, but there is no help there. I know that I will probably have to replace the mobo ($139.95), as this would be more cost effective than purchasing a new PC. Thanks in advance for your suggestions.
