Apparently i made the unfortunate mistake of ordering a computer from cyberpowerpc. it ran fine for a while but now any time i open a game, i can play for around 5 minutes before my monitor shuts off and gives me a display not found message. my dad and i basically went through the entire computer disconnecting and reconnecting cables, and for about a week it was fine but of course on the night of the elden ring release here we are again. i have absolutely no clue what i can do because no matter what i search I've done it. video cables, driver updates, factory reset of pc and monitor but nothing is working. please help.
