You've just installed a VGA card in your motherboard it could be that you need to chnage the bios settings to work on AGP and not onboard, but we need specs first.
Your board has onboard VGA and there for I would recommend going into the BIOS. Set it up to work from your AGP card as it could still be set on the onboard card and that could be why the memory is not showing up right.
hi, managed to sort out graphics, there was no option for on-board it said PCI or AGP i selected agp as it was set on PCI. now i checked RAM, its saying in BIOS total physical memory, module 1 slot 1gb , module 2 0 (Zero), why could this be?
