System unexpectedly powering off without warning.
System unexpectedly powering off without warning.
Hello, it seems your PC has been experiencing random shutdowns recently, making it hard to boot again. The PSU, motherboard, RAM, and cooling system were all updated about a year and a half ago. Could you share more details about the problem? Thanks for understanding—I’m really trying to figure this out.
I get it—this can be really annoying! Don’t stress about the complaints. Did you adjust any settings in UEFI/BIOS before the issue began? It looks like your PC might be overclocking itself! Does it actually start up and then suddenly stop after a certain time of use? Have you been keeping an eye on temperatures to rule out overheating? I’d be happy to assist further if you share more details!
I haven't altered any settings in the BIOS. It starts up properly and for a couple of days it functioned well without the problems I encountered, the display only attempts to boot after unexpected shutdowns. For example, it can power down when using Photoshop or during random sessions while working with Google Sheets, not just during specific tasks. I monitor temperatures using Ique.
It appears the device is having trouble getting power, possibly due to a power supply issue. Re-seat the power cables and consider unplugging the reset and power button before turning it on manually, just in case a short is present—no signs of damage were observed.
I questioned whether the problem stemmed from the power supply unit. The Corsair RM750 (modular) inside might seem sufficient, but I’m considering going a bit further.
What issues appear in the Event Viewer? If the Kernel power event ID 41 is present, it could indicate a PSU problem. From what it shows, the system isn't receiving power properly—like lights failing to turn on—which strongly suggests a faulty power supply unit. Alternatively, it might be a good PSU but with a defective motherboard (less common). Either way, both scenarios can result in power loss.
I've acquired a new 850 and plan to install it. If this resolves the problem permanently, I'll repair the other one since it's covered under warranty. Thank you all for your assistance—I'll let you know once I'm 100% sure it's the PSU.
