Hey everyone, I’ve been running into a specific issue recently on my custom-built PC with a couple of games in particular (Witcher 3 and NBA 2k15). The problem is similar; at some point, the screen suddenly turns to black and video signal is lost. Nothing responds (even though power is on), forcing me to do a hard restart of the entire computer. With NBA2k15 it happens randomly, with the Witcher it happens at a specific point in the game (sometimes I get to go a little further, but it’s usually around a specific point).
Some steps I've taken:
Cleaned out the tower fans just in case.
Reinstalled the games.
Replaced PSU, just in case the old one was defective.
Updated all drivers
Ran memtest (no errors detected)
Under throttled GPU and memory by 40 MHz.
Ran Furmark for around 20 mins without issues.
OS - Windows 10

Any help would be much appreciated. Thanks in advance!
