WIndows 10 Blank monitor

I have been having some of the strangest, at least for me, problems lately.

Here’s the present problem. I updated the motherboard in a desktop to an FM-A55M-E33 board. I installed W10 and everything was fine. I updated the computer to the latest version and now when the desktop is booted everything works fine until it boots past the BIOS screen then there is an “explosion” of color on the monitor and then the screen goes black.

I can connect the desktop to another monitor and everything works fine. I can connect the black screen to another desktop and everything works fine. But when I connect the black screen to the FM “desktop” after BIOS I get the “explosion” of color and the screen goes black. Any ideas.

Have you tried a different video cable? i would also see if the video driver was updated and if so, revert back to previous driver.

The monitor works if I connect it to another computer. One thing I forgot to mention in my original post was that the monitor was working with the computer mentioned. I had to computer updating to version 1903 and when I came back the monitor was black and hasn't worked on that computer since. Thanks for the reply.

have you tried plugging the cable into internal graphics port therefore bypassing the GPU .
See if the CPU will bring it back to life
