During CPU stress tests, the process completes smoothly until I halt it, after which my computer powers off. I've used OCCT CPU test and Prime95 SmallFFT; both worked fine even with single RAM sticks. Everything remains at default settings, no overclocking applied. Initially, testing began because Helldivers 2 would restart my PC within a minute once connected to the ship (with GPU installed). Now it restarts immediately after launching the game. I've tried re-seating the CPU, but it didn't help. No bent pins were visible in the socket. Could this point more toward a motherboard or CPU problem, or is it likely a power supply issue? My system specs are: Windows 11 Pro 64-bit, Asrock Z890 Pro-A Wifi (2.21), Intel Core Ultra 7 265k 2x16GB Team Group T-CREATE Expert (currently 4800MT/s), MSI Spatium Series M482 2TB SSD Seasonic G-Series 650w (first use in about five years), ONIX ODYSSEY ARC B580 (removed completely).
Turn off the integrated GPU (probably a problem with Intel 200 models?) and verify BIOS settings using another power supply unit.
Thanks! I'll wait to buy a new PSU and check if that resolves the issue. I already updated to the beta BIOS and turned off the IGPU, but it didn't help.
Use HWiNFO to check the AC and DC loadline settings. Lowering these numbers can minimize big voltage swings to the CPU during sudden load termination. The default values seem to be around 1.10 for both. On an older 10th Gen system, I reduced them to 0.25 mOhm and it stopped crashes from full load to no load. My Seasonic power supply might have been the issue, which is great because I didn’t have to replace it. After adjusting the loadlines, I’ve been using it for years without problems. Keep an eye on the VCore voltage reported by HWiNFO for any spikes or drops during tests. A short Prime95 run (~15 seconds) should suffice.
