Hello, I own an older setup featuring an i5 9400 processor, 16GB DDR4 memory (Corsair + GSKILL), an XFX RX 5500xt thic ii pro 8GB (last 5 years), a Gigabyte H310M M.2 2.0 (3 years), a PSU from Gigabyte P450b 80 plus bronze (3 years), several HDDs, and a 128GB NVMe SSD running in X2 mode. I experienced a bad sector on one mechanical hard drive, but the NVMe SSD shows 93% health according to Crystal Disks. The system has run smoothly for a long time, yet I’m facing several problems recently: 1) In sleep mode, no display appears when waking up—initially rare but now constant. 2) Occasional black screen upon powering on; required a hard reset or removed all USB devices to see output. 3) No stuttering or freezes during gaming or heavy tasks, but issues arise after intense work sessions with sleep. 4) Reliability Monitor flagged critical kernel errors (code 31), preventing GPU initialization, etc. 5) I’ve tried updating drivers and various troubleshooting tools, but nothing resolved it. Could you help pinpoint the main issue in my system? ChatGPT and Gemini suggested it might be related to the PSU or power supply unit.
You changed the monitor, and your PC began acting differently once the 60Hz TN screen was replaced by a 144Hz 4K model.
