My PCI-E cards are not detected by my computer!!! I think I need to disable onbo Tags: Graphics Cards BIOS Computer PCI Express Graphics Last response: March 22, 2009 3:24 AM in Graphics & Displays Share mystic1knight March 22, 2009 2:41:21 AM I have made it work before by setting "memory buffer size" to "disabled" in BIOS. (I think) But it won't work anymore and I have to use my onboard video. Does anybody have any ideas of how to fix this? Maybe flashing the BIOS? PLEASE HELP ME ANYBODY!!!
