I recently attempted to upgrade my graphics card. I was using a nVidia GeForce 210 on an ECS H67H2-M2 motherboard. My power supply is 500W. I purchased a MSI GeForce GT730 and it seemed to seat well. When I turned on the computer I got nothing but the revolving circle. I put back the old card and everything worked fine. I am extremely amateur to computer builds so I may have left out important facts but I am curious to see if any one has a solution.
