I recently bought a graphics card and made sure that it met all of the system specs with my computer, I then attempted to install it. I was promptly given 6 beeps upon starting up my computer. After looking for a while, I found out that there is a security feature on windows 8 that keeps me from installing things to my PCIe port until I turn it off. I turned off the security to said PCIe port, and as a result, I could plug in my graphics card without error, however, when I try to use the graphics card, my screen remains black.
I tried the same graphics card on another of my computers and it worked fine.
Any idea what my next step should be?
