My PC is only about two years old, but it has started crashing more and more often. During the first year, it would occasionally crash after long gaming sessions, but now it can freeze, show a black screen, or reboot unexpectedly. Event Viewer shows many Kernel-Power Event ID 41 entries stating that Windows did not shut down cleanly. I have also seen BugCheck, volmgr, SideBySide, EventLog, and Service Control Manager errors.
I have updated Windows and my software, reinstalled several motherboard and graphics drivers, and tried troubleshooting display drivers. Nothing fixed the problem, and the crashes seem to be getting worse. Sometimes the computer crashes before I can collect more information.
The system is running Windows 11 with an ASUS TUF Gaming B650-PLUS WiFi motherboard, AMD Ryzen 5 9600X processor, MSI MAG A750GL PCIE5 750W power supply, 32GB of TEAMGROUP DDR5-6000 memory, and an ASRock Challenger OC Intel Arc B580 12GB graphics card.
Could this be caused by the CPU, graphics card, motherboard, RAM, storage, or power supply? What would be the best way to determine whether this is a software problem or failing hardware?

Kernel-Power 41 usually describes the result rather than the cause: the system lost power, locked up, or crashed before Windows could shut down normally. A clean Windows installation from a USB installer is a useful way to rule out damaged system files and driver problems. Disconnect other drives during setup, install Windows with the default drivers first, then install the latest chipset, motherboard, and Arc graphics drivers from the manufacturers’ support pages. Back up anything important before deleting partitions or changing disk settings. If the crashes continue on a clean installation, hardware becomes much more likely. Test the RAM, CPU, GPU, storage, and power supply individually where possible.
The power supply is worth checking even if its wattage looks sufficient. A failing supply, loose connection, or unstable power delivery can cause freezes, black screens, and sudden restarts without producing a useful Windows error. Check that the motherboard, CPU, and graphics-card power cables are firmly connected, and look at the BIOS hardware-monitor readings for anything unusual. If possible, testing with a known-good power supply is more reliable than judging the voltage readings alone. Also avoid changing BIOS settings or wiping drives until important files are backed up.
The BIOS readings look broadly normal from what I can tell, but I understand that does not completely rule out a power-supply problem.
Try reducing the problem to the simplest configuration. Boot into Safe Mode, remove the graphics driver with a proper clean-uninstall tool, reseat the RAM, and test each memory stick separately. Also run a full health scan on every drive and check whether the system remains stable with nonessential USB devices disconnected. If it cannot stay running even in Safe Mode, that points away from a normal graphics-driver issue and toward hardware, power delivery, or a deeper system fault.
I’ve already tried Safe Mode, reseating components, and reinstalling drivers without success. At this point it sometimes crashes before I can complete another test.
I’m starting to suspect hardware too. The crashes are now frequent enough that I may not be able to keep the system running long enough to troubleshoot normally.
