System unexpectedly powers off during gameplay, CPU indicator illuminates
I experienced issues with my motherboard PRO B650-P WIFI CPU AMD Ryzen 9 7950X3D GPU RTX 4070 TI Super Gigabyte PSU Corsair RMX Series RM1000X. After playing Escape from Tarkov for four hours, the system powered off without a blue screen. I had to restart it manually. When I did, the red CPU light faded and disappeared after a restart. The Event Viewer showed no errors or critical issues, similar to what occurred with Total Warhammer 3. It took about thirty minutes to an hour for the shutdown process. Dead Rising Deluxe Remaster required three hours to shut down, while CSGO 2 took thirty minutes but only once. I brought it to a repair shop where they swapped the motherboard to PRO B650-P WIFI and resolved the problem. They stress-tested it and bench-tested it for eight consecutive hours at full load without any crashes. After returning home, the issue persisted—replaced the PSU with Corsair, but an APC battery backup problem continued. Silent Hill 2 Remake and Space Marines 2 functioned normally without any issues.
Not running 24/7, I'll tackle it when I can. You've confirmed it's connected to the Battery + Surge port, not the surge socket? Probably your circuit light isn't lit. Can you connect all other devices to the surge and keep the tower running only on the battery plug? Everything you mentioned seems like a power issue—maybe some unusual EM interference. Try stripping down to the bare minimum peripherals. It's possible a USB device or monitor is causing the problem. Run a stress test to see if it triggers. Use HWMonitor to verify voltages match ATX specs. Turn off any unnecessary software and keep an eye on things. Don't forget to disable any overrides you might have installed.
the pc is the sole device connected to the battery, which is also plugged into the surge plus battery. there’s no circuit light indicating stress testing; it ran for 30 minutes without issues, all outputs were off. even when using just mouse and keyboard, warhammer 3 still worked, though the mouse and keyboard switched USB remained active for the motherboard. the issue originated on my old motherboard—after switching to the b650-p, the problem persisted, and voltages met atx standards.
