I recently purchased sapphire 6650xt. Before installing it i had a 7950 that worked with my monitor.I have used ddu to delete old amd drivers,put the new card in and no display port signal. After multiple restarts and a few pc repair prompts (somehow my boot drives order was changed) i manage to make the card work. It worked for a few days and again, today no dp signal.The monitor works fine with the igpu,but i have to do multiple restarts until the card works.I have changed the cables, the same thing. Is it the card or something else? Thank you.
