Over the past two weeks my PC has been shutting down unexpectedly, without any blue screens. The monitor stays on. The last time I changed major parts was about a year ago and everything has been fine so far. When it powers off, I have to step away for a while before it restarts quickly again. During this brief period I checked the CPU and GPU temperatures, which were normal. Looking at the event viewer it displayed ‘kernel power error’, suggesting a possible power supply issue. I’ve installed the newest drivers and Windows updates, and recently added a new 850W power supply which seems to have fixed things. However, this morning while using ZBRUSH—a sculpting program—I experienced the problem again. Now, when I attempt to restart, the PC shuts down after just five seconds. Could it be the software that triggered this? Since this was my first time encountering it while using ZBRUSH, I’m wondering if another component might be involved. Any advice would be greatly appreciated. I rely on my rig for freelance work and need a solution quickly. Cheers, Dave

Experienced with kernel power issues when aggressive power settings were active. Adjust BIOS to disable certain power-saving options and verify your Windows power plan is set to High Performance. It might also be a case where the system attempts excessive speed beyond available electricity, which can often be fixed by lowering the CPU power budget in BIOS if accessible.

I’ll give it a shot, just need my rig to start up without powering down right away.

Can you tell me if you can access the BIOS settings? If so, does it shut down after staying open for over five seconds?
