Hello, I upgraded my PC a couple years ago with a new motherboard
ASUS P8 B75 -M /CSM 4 gigs Crucial ram, 500 what power supply and EVGA GeForce GTX 750 Ti video card. Everything working great. The video card stopped working after helping a friend with his PC and using the VGA port on my monitor, I did disconnect my DVI from the monitor before plugging his computer into the VGA Port. I have removed my video card and now using onboard DVI. I have reinstalled it, but not working, how do I know if it is an issue with the video card or the motherboard ? Also, can you reccomend testing software for all components of my PC ?
