I just replace my power supply/ motherboard. Both are brand new i'm still not getting vga signal i'm confident I plug in everything correctly. Could this be a Gpu problem or my cpu ? Everything turns on perfectly all fans are running cpu fans too led are working. My motherboard is asus maximums hero vi. They dont have build in vga port i can plug in. I spend alot of money into this computer i have no idea what to do now. My video card is evga gtx 760. My Video card both fans are also running. I also brought my computer to and test on my brother monitor It also has no signal so it not the monitor fault.
