Hello, Your computer powered off unexpectedly with no warning, and even after checking the outlet, the PSU only clicked once when you pressed power. You replaced the PSU and ran the SATA and GPU checks, but it still won’t turn on—no indicator light and no clicking like before. This suggests a possible motherboard issue. Are there any other steps you can try to verify? Thanks!
