I've the microtower version of HP dc5800 series desktop and I'd like to upgrade it with an Asus 8600GT graphics card in hand.
I installed the card to the suitable slot. When powered up, fan on the video card starts to spin.
But I cannot get video output. I tried to set the "on board vga" option to "disabled" from bios but it doesn't get saved. If I reboot and re-enter bios I find it set to irq5 again. Also there is a 2 pin cable attached to the video card which I couldn't find a proper point on the mobo to insert its other end.
What do you advice that I shall do to get over this issue? thanks in advance
