Black screen when activating SLI.
Heyyo,
Tbh? At this point I would do a data backup and reformat windows and make sure it's not a corrupted OS.
Next if that doesn't fix it? Run memtest86 to test your RAM and also do a test on your GPU with something like MemtestCL.

For memtestCL? You have to specify how much memory and stuff. To run it? Hold shift, Right click on some empty space in the same folder as the memtestcl.exe is and use commands such as this:
memtestCL.exe -g 0 -b 1700 100
the "-g 0" is GPU number. 0 and 1. 1 being the second GPU so you have to do a separate run for each GPU.
the "-b" just prevents uploading the info to Stanford research computers of your results and hardware.
the "1700" is how much VRAM that GPU has in megabytes. I have a 2GB card so I put about 1700 since windows is using about 230 MB of VRAM but I probably could have gone up to 1800 or so to test as much as possible.
the "100" is just how stringent it should be on testing every memory block. How many test iterations to try.
