I am trying to upgrade my computer. So far I've successfully upgraded the CPU, RAM and wifi/bluetooth adapater. However, I have not been able to successfully upgrade my video card. I've purchased two different cards and when I install them the computer powers up but the screen is black. It seems like the computer is still functioning because when I remove the card and boot using the onboard video the system has installed drivers for each of the two cards I've tried.
This is my computer:
These are the two video cards I've installed:
I noticed that my computer doesnt have a cable connected to either the MXM_LVDS or UMA_LVDA ports which are located right above the MXM slot. Is this related to my problem? I've inspected the hardware and there does not appear to be a lose cable anywhere. As far as I can tell there is nothing to plug into either one of those two ports.
I have also updated my bios, disabled secure boot and all power management functions (suggestions I read in other posts). So far nothing has worked.
I've included a copy of my msinfo32 and a picture of the motherboard. I'm at my wit's end, so any assistance would be greatly appreciated.

Your 27" machine is not in BOTH lists therefore the simple answer: they are not compatible with your machine.

I have reviewed all available manuals as well as the "buying" website and found no listed Video cards.
However, if your system is booting with a UEFI type setting in the bios, there may be a security issue that is keeping you from adding a video card.
Go into the bios setup and see if you can find anything about a "legacy" booting option. It may require you to disable the "secure boot" to do it. Once you can boot in Legacy mode, it MIGHT be possible to install a Video card that will work. From what I have read, though, you may not be able to display anything on your primary monitor because it is not being driven by the new video card.
Here is a reference to what I was talking about in another message.
Near the bottom of the discussion, it talks about the UEFI/Secure boot issue.
