I really don't know if it's a problem with the video card or the mother board or with what so anything would help. When I connect the VGA with the motherboard it works just fine, but after connecting the video card it goes black after the Windows Starting logo. At first I thought it was the video card, which is a Sapphire Radeon HD 7870 GHZ OC 2 GB 256 -bit GDDR5, so I went ahead and bought another one, XFX Radeon R9 270X 2GB DDR5 PCI Express 3.0, same thing, but newer generation. Still didn't work. BTW when using the video cards I use an HDMI not VGA. I use the VGA for the motherboard only.
The first time I set up everything, my cousin who is a computer technician helped me, so we did plug in everything properly. He thought it was a problem with the drivers or compatibility, and I thought it was a problem with the BIOS or the PSU. He also helped my brother set up his rig, but he didn't have this problem.
Please help and thank you.
