I recently installed an RX 7600 XT along with a new power supply. GTA 5 runs normally at 60 FPS, but raising the limit to 120 FPS eventually causes a black screen and a "no signal" message on the monitor. The computer remains powered on, the fans keep spinning, and temperatures look normal, but the system becomes completely unresponsive and I have to hold the power button to shut it down. I've already tried several fixes, including reinstalling Windows. What could be causing this, and how can I troubleshoot it?

The Windows graphics reset shortcut is Win+Ctrl+Shift+B, but it only helps if Windows is still responding. If the whole system is frozen and the monitor reports no signal, the shortcut probably won’t do anything, so you’ll need to investigate the driver, power connections, and hardware instead.
Start by verifying GTA 5’s files and doing a clean reinstall of the graphics driver. Using a driver cleanup tool in Safe Mode before reinstalling the latest AMD driver can help rule out corrupted software or compatibility problems. Since the crash only happens at a higher frame rate, temporarily cap the game at 60–90 FPS and test another demanding game or a GPU stress test to see whether the issue is specific to GTA 5.
I already reinstalled Windows, but I’ll try a clean graphics-driver installation and test with another game.
Check that the GPU is fully seated and that its power cable is connected directly from the power supply rather than through a loose adapter or overloaded cable. Also try a different DisplayPort or HDMI cable and monitor input. If lowering the FPS or power limit prevents the crash, that points toward a GPU, power-delivery, driver, or stability issue even if temperatures appear normal.
I tried that kind of shortcut, but the computer doesn’t respond to any key presses once the screen goes black.
