I’m sure you’re all doing fine. If you haven’t caught up on my updates, check the links below: /#comment-16683310 In the past two months (starting February 2025), my PC has been acting strangely. It’s been like it was “controlled” by someone else. After a 10-year wait, it began displaying strange signs and would crash with a green screen. At first I thought the graphics card was the problem, but later noticed another pattern: the system would power off with a black screen while fans and RGB lights stayed on. It also would shut down unexpectedly during gaming, especially with titles like The Last of Us Part I and Cyberpunk 2077. I had to force a hard restart to get the display back. After swapping the GPU via an RMA, I suspected a PSU issue and upgraded to a higher wattage unit. Still, the reboots kept happening. I thought about RAM problems, so I bought a lower-speed kit from a QVL listing. I ran diagnostics like OCCT and FurMark, tested MemTest86 on old RAM, reinstalled Windows several times, upgraded the CPU cooler, and even plugged the PC directly into a wall outlet. I changed components one by one, but the problem persisted. Eventually, I replaced the motherboard with a model featuring better VRMs. Still, reboots continued. I’ve tried everything—every test, every fix. The error in Event Viewer says “Kernel-Power - ID 41.” I haven’t changed my CPU, but if it were the bottleneck, it would shut down during CPU burner tests. Parts I’ve altered: - GPU: 6800 XT → 6900 XT - RAM: Kingston 32 GB (3600 MT/s) → Patriot Memory Viper Steel 32 GB (3200 MT/s) - PSU: MSI 850W → EVGA 1000W - Board: ASUS Prime B550-PLUS → ROG Strix B550-F WiFi II (BIOS outdated) - CPU: 5600X I’m still unsure if it’s the SSD or the CPU. When automatic reboots happen, all LED indicators light up but the screen stays dark. I can even hear Windows launching. I’m running Prime95 as suggested, and if it runs smoothly for a few hours without shutdowns or errors, I’ll assume the SSD is faulty. It’s quite old and still has its OS. DOCP is disabled while Prime95 runs. Edit #1: I’m using Prime95 to test performance. If it doesn’t show any issues, I’ll rule out the SSD. Edit #2: Ran Prime95 without DOCP from 2:18 PM to 3:00 PM – no crashes or errors. Edit #3: WD_BLACK S.M.A.R.T. Diagnostics completed; no faults detected. Edit #4: I’ve also tested Prime95 with DOCP enabled from 3:02 PM to 3:43 PM – clean results. Thanks for your help, @KidKid.
The temperatures are currently stable across your system, with the CPU operating within normal ranges.
Have you checked Prime95 for any stress worker failures? Also, would disabling XMP/DOCP on the board and testing for stability be a viable alternative?
I've turned it off now. I plan to run and test without DOCP for a few hours or days. I'm unsure about installing or using Prime95. Do you have a tutorial video?
Prime95 can be obtained from the site: Download - Prime95. Numerous tutorials are available for installation and usage.
Everything I attempted hasn't resolved the problem. Upgraded GPU, RAM, power supply, motherboard... it still fails after a short time. If my CPU Prime95 shows no errors within a few hours, could this be related to the SSD? Right now I've turned off DOCP.
