The computer stops working abruptly and can't restart unless you manually switch the power supply on and off.
Looking for guidance on what might be causing your computer problems. You're using a 5900x with a B450-i board, a 3070 chipset, and a 600-watt SFX-L BeQuiet PSU. In the past 24 hours it has shut down repeatedly without warning, stopping only when you switch the power on and off. The motherboard lights stay lit during shutdowns until you turn off the PSU. You mentioned recent storms and a power outage over the last two days, which caused flickering lights and a two-hour blackout due to construction work. You suspect the PSU might be underperforming or damaged, especially since it was bought in August 2020. Any other explanations you're aware of would be helpful.
It seems like a possible sign of an overcurrent protection issue. You might be drawing more power than necessary in certain situations, which could cause your power supply unit to trip.
Sure, I thought about it but the unexpected shutdown usually occurs while I’m working with spreadsheets and documents, not during intense gaming sessions. It seems we’re on the same page—it looks like a power supply issue. It probably needs to be replaced or returned under RMA. Could it be something else besides the PSU?
When using the system normally, like browsing the web, a brief maintenance check may be necessary. Ensure there are no corrupted files on the system. If the problem appears only during gaming, your PSU might be failing to supply power properly, possibly entering protection mode due to overload or surges. Over time, components degrade, and even minor issues can push the PSU past its limits. If your motherboard includes built-in video, connect a monitor and run it for a few hours to test stability.
Hey 191x7, I’ve disabled AMD’s XMP feature and it seems to fix the problem. After several hours of 3D mark testing, everything looks good. Hope you have a great gaming night—maybe the issue won’t come back! Thanks for all the help.
