Recently when I launch a game, as the game shows splash screen and begins to load. the display goes in standby and system freezes with all fans and lights running but no response from keyboard or mouse. If I underclock my gpu clock speed to around 1520 mhz, the game runs fine and cool. But if I take it back to default clock speed, the freeze and display standby mode thing happens again. Can anybody suggest as what could be wrong? My system config is core I3 12100f, 16gb ddr4, asrock rx6600xt gaming phantom gpu on windows 11 64 bit.
