Hello, I am updating a computer with a graphics card. I have only been using the built in graphics and I upgraded to a 4k monitor and thus I needed to buy a graphics card. The computer is a Asustek CM5571. I am trying to install a MSI Graphic Cards GT 1030 2G LP OC. I tried to just plug and play, however nothing showed up on the screen (not even the bios) with either the built in graphics nor the new graphics card. The graphics card requires 300W and the computer has 350W. So I tried reseting the bios, but that didnt work. I double checked that the bios would look for the PCIe slot first. I then disabled the internal graphics and restarted with the new graphics card installed, but to no avail. I then tested the graphics card with another computer and that worked. I don't use this computer for gaming, just internet/pictures so I thought I would just update the current computer with a new monitor and a capable graphics card. Any thoughts on what is happening or other ideas to try?
