hi, so I recently had a compu6ter built for gaming which is completely starter level and have a graphics card rx560 its been a year and I have had a recurring issue in which I get random black screens and my computer hangs up after which I have to hard reset it. I have tried multiple things such as rolling back drivers and manually changing fan-speed all of which to no avail kindly help in as to what I can do I have scoured the internet and have seen many people facing a similar issue but none have been able to solve it.
