I am having a strange issue with my HP ProDesk 400 G4 when I install a PCIe card into either PCIe slot, the memory is cut in half. The system currently has 2 8gb dimms installed so without a PCIe card installed, the system has all 16gb and with a PCIe card it only has 8gb. I have gone through the BIOS to see if there was possibly a setting that could cause this and have been unable to find anything, I also did a BIOS reset and still the system will only show 8gb available when a PCIe card is installed. Any help to solve this would be appreciated.

@swishnets -- some graphic adapter cards do NOT have any RAM on the card. What then happened is that your card has "borrowed" 8GB of your RAM, to use for video-processing, leaving only 8 GB for Windows to use.
Exactly which card do you have? You may need to purchase a different card that has its own RAM. Note that such "onboard" RAM usually is faster than the RAM on your motherboard, which is a "bonus" to you.

@swishnets -- open the Windows "Task Manager". Click to the "Performance" tab.
How much RAM is showing as "used" ?
Are there any device-drivers for the NIC that you have downloaded & installed, or did the NIC come with a CD-ROM that contains some older (?) device-drivers?

Yes, I have the drivers from Intel. As far as the amount of memory that Windows shows I will need to install Windows on it to see if it is able to see all 16 gigs. I know the bios only sees 8 of the 16 gigs when the nic is installed.

@swishnets -- so, we're back to your initial posting:

Does this happen if you install a different card ?
What happens if you start with 24 GB of RAM? Still reduced TO 8 GB, or is it reduced BY 8 GB?
