PC fails to awaken from sleep and suddenly powers off unexpectedly.
Hello, I'm facing some issues with my PC that seem to shut down unexpectedly. When it does, the screen cuts out and power is cut off from devices like the mouse, keyboard, speakers, CPU, GPU, and case fans, while the fans spin normally. The PC won't turn back on for a few minutes or even an hour, and this happens randomly even when the system is idle. Could this be related to my motherboard or power supply unit? Any advice would be greatly appreciated!
Looks like a PSU problem. Mentions capacitors getting too hot and needing cooling before charging. What are your specifications? Updated August 6, 2022 by An0maly_76 Added more details
Sorry for the delayed response. Regarding my components: I have an ASRock B450M HDV R4.0 with AMD Ryzen 5 3500, a GTX 1650 KLEVV at 2666Mhz, 8GB RAM (2x), Antec 500W 80+ White power supply, and a 256GB SSD plus a 500GB HDD. I’m not sure if the issue is with the PSU itself, since the fans are working normally. When the system shuts down, all fans run at normal or max speed, even when the GPU isn’t getting power. It seems the system won’t shut down forcefully every time it loses power—usually it just cuts off completely. Is this behavior typical?
It might be related to the motherboard. Power supplies can sometimes stop working in parts, allowing some functions to work while others fail. The sudden shutdowns and waiting periods suggest overheating capacitors and faulty solder connections causing fan issues.
