Am I able to upgrade my graphics card?

Solution
As long as your motherboard has PCIe slots which is most likely does yes you can upgrade the graphics card but there are some considerations.

- Your only modern card options would be a low power card like a GT 1030 or a GTX 1050.

- Your CPU is going to bottleneck any graphics cards that are modern. They will work but will not perform to their fullest.

- If your PC's power supply says 400 watts on the side, power will not be an issue. These 2 cards can run on low wattage power supplies and don't need special power connectors.

- A newer graphics card may cause the PC to fail to boot due to the card needing a more modern UEFI supportive motherboard to function. If this occurs, you will need to upgrade the PC completely (New CPU, RAM...

If this occurs, you will need to upgrade the PC completely (New CPU, RAM, motherboard) in order to get a modern card to work. You could also try older cards like Nvidia 200 or 600 series/Radeon 200 series.

- These smaller cards will fit in the case and don't require good airflow. If you wanted a more powerful card like a 1060 these would become issues.

- Even if you got a 1030 GT and the BIOS worked with it, it STILL may not work because the motherboard may not be able to provide enough electricity through the PCIe if it's older and OEM.

TLDR: You can upgrade your graphics on that PC but there are no guarantees that the card will work with it. The only way to know is to try a new graphics card in it or upgrade the PC all together.

I see no slot on that motherboard for the videocard, sorry. That's a pre-built, which means the form factor might not be standard, so you might not be able to find another motherboard that fits in that case. And even if you buy another motherboard and a new case, well now you will be buying 3 things- the motherboard, the case, and the GPU.

It doesn't sound worth it to me, but maybe you have use for this computer.
