The computer shuts down unexpectedly.
The computer shuts down unexpectedly.
i had this pc for 2 years now and i never had an issue however now it just turns off and restarts after 2/3 hours or even less it started 2 days ago when by mistake i turned off the wall socket (in the UK there is a switch) whilst my pc was one when i turned it back on it gave me with an error screen something about some "BIOS error" and it made me enter this window where it told me 2 ways to boot, im not sure but i clicked the first one (i know not much detail and very vague from my part i thought nothing of it as it happened it the past and i never had an issue) after my PC booted up it now just switches off like someone pulled the cord and puts it back in instantly, i mean the LED inside switch off and turn back on, the fans go quiet for a splitsecond and restart any ideas on how to fix this ? it disrupting my work
After turning off the power to the PC, I reinserted the socket plug. The machine restarted and displayed the BIOS menu, indicating an error. It mentioned that before this problem, fans were noisy, but now they are very quiet. I wonder if the settings in my BIOS have been reset.
The BIOS is saved in EEPROM, not changed directly. It remains stable unless you perform a flash operation, because EEPROM is read-only. Adjustments made to BIOS/UEFI are temporary and reset when the CMOS power is interrupted or the circuit is disconnected. The CMOS battery on the motherboard keeps these settings active.
Event Viewer highlights critical errors and warnings, displaying causes like system failures or hardware problems. The absence of such entries suggests a power supply (PSU) fault.
Warning: The app-specific permission rules don't allow Local Activation for the COM Server app using the given CLSID. I'm unsure what that means. I updated my PSU about eight months ago, switching from a low-end model to a Corsair RM550X.
That's a common one, warnings aren't nearly as problematic as 'critical' or 'error'. You should at least be getting an 'unexpected shutdown/failure' critical/error.
The system experienced a critical failure after a sudden shutdown. This issue might stem from the hardware not responding properly, encountering a crash, or losing power unexpectedly. The error message indicates a processor core problem, with specific details pointing to a machine check exception. The reported component is the processor, and the APIC ID varies depending on the model—sometimes 15 or 2.
I was mainly trying to identify the 'fatal hardware error' you encountered. Such issues often appear when your PSU is unstable, possibly due to a failing power supply or an overloaded outlet. If you have a switchable outlet, the switch itself might be damaged after handling a heavy load like a computer. Regardless, it’s wise to install a UPS for your PC to provide power conditioning, surge protection, and safer shutdowns during outages. This could help if there’s damage in the electrical circuit supplying it, whether at the outlet or the switch. If a UPS doesn’t resolve the problem, you may need a new PSU, but you’d still have protection from the UPS. In my experience, my home office uses a 1500VA unit as a baseline. The larger the better—consider not just the power capacity but also durability, build quality, and extra features like LCD displays for monitoring. A 1000VA model with a functional front LCD is ideal; it lets you use it as a watt meter and track events without wiring up cables. If your network gear is nearby, you can usually install it there too.
