You try your GPU in another PC. If that fails, you have the motherboard (and what's on it) or the PSU to check out.
I just got back from a 3 month vacation, and I had to have all of my electronics shipped back. When they all got to my house, I set everything up. Now when I press power, all the fans function normally, but my monitor is not getting signal from the GPU via Displayport. Also, my mouse and keyboard are not lighting up like they are supposed to, but my headset is. I checked every single last cable to make sure it was plugged in completely, and it is. I also tried to HDMI port on the GPU, that didn't work either. I know it is not a problem with my monitor, mouse, or keyboard, as they are working completely fine on my backup computer, which is what I am on now. Could it be possible that during shipment, the GPU broke as well as some of the motherboard?
If it matters, my GPU is a GTX 750 Ti and my motherboard is a MSI 760GMA-P34. Any help is greatly appreciated. If you do believe they are broken in some way, what would be some good alternatives that are around the same price?
