Show your PC's monitor unexpectedly halts and loses GPU output signal
Hello, Your PC details are as follows: CPU - AMD Ryzen 5 3600x, Motherboard - MSI X570 A pro, RAM - Corsair Vengeance LPX 16GB, GPU - GeForce GTX 1660 Super, Storage - Samsung SSD 970 EVO Plus NVMe M.2. Your system has random display issues where the monitor stops receiving signals from the GPU. Sometimes the fan spins at full speed when the display loses signal, and the PC runs smoothly otherwise. Occasionally, while watching YouTube in Chrome, the screen goes black but audio plays. Pressing alt+F4 closed the browser and shut down the PC, indicating normal operation when signals are lost. The display signal problem appears unpredictably. I’m unsure what to do. Assistance needed.
Your PSU's wattage and brand are unclear. Some videos suggest issues with cables or ports, possibly indicating a weak PSU. It could also be related to the monitor. Could you share the model?
I checked the situation carefully. The PSU might be the issue, as it could have provided incorrect voltage affecting the GPU. To verify, test the PSU with a multimeter or replace it temporarily to see if performance improves. If problems persist, consider contacting the manufacturer for further diagnosis. Let me know if you need more help!

I’m not sure if this PSU is reliable. Gigabyte makes the motherboard, so they didn’t actually build it—they probably made a similar product. (Superflower does some decent power supplies, but I’m skeptical.) Video cards tend to fail sometimes. It seems the chances are good it’s okay. If you’re curious, try a PSU tester or use a multimeter, though that’s time-consuming. You’ll need to check each pin individually. PSU testers are affordable and cover multiple cables at once. If you purchase one, get a digital display. The basic ones with just an indicator light aren’t useful.

Learn the PSU tester signals by identifying normal values. OK readings include voltage levels within the manufacturer’s range and clear error codes. Unacceptable signs are unstable voltages, repeated errors, or inconsistent readings that suggest a fault. Refer to the manual for specific thresholds.
PSU tester functions similarly to a multi multimeter. The ratings for PSUs typically range 5% above and below the rated voltage. It doesn’t measure flutter.
