Having a strange issue. Came home last night and my pc would not boot to the start screen or bios. Thought it was the ram first. Tried that. No go. Figured out that if I take out one of my gpus it works fine. Goes to bios and everything. After taking out the second gpu and putting it back in. The computer now boots to the start screen. But stays fully black threw the bios and windows loading screen. It only shows up on the screen when I get to the login screen. Then the computer seems to be working fine. But If I restart it. It does the same thing 100% black till the login screen. I even tried the boot to bios shortcut on my desktop. If I try that. It just stays black period. Never even gets to the login screen. Little help would be appreciated. As I have never had this issue or seen it before.

Hi offroadracer516. What Bios version are you on, If not the latest, then recommend an update and reset to defaults.

Have you tried swapping GPUs to same slot to test each card, and that sockets and contacts are clean and card well seated.?
Are any of the post state LEDs lighting up on the MB? If so report which one.
