I just got a MSI GTX 970 Gaming 4G Graphics Card but once I connect the PCIE cables to it my system won't boot up. The lights will come on for a second and then it powers off. I tried it first with a 550w PSU and thought that it might not be enough power to run it, so I upgrade to a Thermaltake 650w bronze, but I get the same issue. I know the motherboard is from an old Hp computer, but that shouldn't be the problem, right? Should I just return the GPU and get another one? I'm a noob at computers so any advice would be great, thanks.
