Gradually cooling the interface while testing for issues, but functionality remains unresolved.
I'm experiencing an unusual problem where my PC occasionally shuts down abruptly. First, the audio would drop, then the internet connection would disappear, followed by unresponsive applications one by one. The interface remained functional, but nothing would open or close properly. A video linked below provides more details. The most puzzling occurrence was complete freezing—even the mouse—while the system stayed powered on without any BSOD. After a manual restart, no event viewer alerts appeared except for an "unusual shutdown." As a 3D artist, I rely on this machine for rendering, modeling, simulations, and editing. My workflow includes Redshift, 3D modeling, Houdini, and DaVinci tools, alongside gaming titles like Path of Exile, Elden Ring, and Witcher 3. When I left it to render overnight, the PC would lock entirely, with the GPU running at full capacity indefinitely (it should stop once rendering finishes). I've disabled everything from startup, runned MEMtest86 with no issues, updated BIOS, used an admin account, fixed files via SFC, and performed benchmarks. Despite these steps, the issue persists. My system specs are listed below:
