My friends computer we built suddenly stopped producing video output. It's been a while and I've tried everything. We replaced the PSU, tried 2 different sets of RAM, 2 different CPUs 3 different graphics card, no graphics card, 2 different motherboards resetting CMOS on both boards. I've tried 3 different (functioning) monitors with functioning cords. Before, on the initial build, we forgot standoffs, none of the other parts switched fixed it and the little speaker made no beeps. this lead me to believe the problem was the mother board. Upon buying a new motherboard and installing, it's apparent that wasn't the case. With the new motherboard, I've tried to put in the disk that came with, and then pressed enter a lot (although I pressed capslock and no light turned on leading me to believe that the keyboard/port doesn't work) in an attempt to get it to install possibly. The only thing I haven't tried is the storage, but could that affect it? If anybody knows what the problem is, and or have a solution, that would be greatly appreciated.
Here's the build: Intel Core i5-3350P 3.1GHz Quad-Core Gigabyte GA-H61M-S1 Micro ATX LGA1155 Motherboard G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory Asus GeForce GTX Titan Black 6GB Video Card Windows 7
The previous motherboard was this : MSI B75MA-E33 Micro ATX LGA1155
