PC just switches off randomly

[aryanpall]

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

Was that BIOS error shown upon reboot potentially related with the CMOS battery? If you do a dry start (no power, attempt to turn on the PC by holding the power button) then try a POST+BOOT, does it give you that same error?

no so the after the power to thje pc was turned off, i re turn the socket plug on and the pc booted it came up with the bios menu saying there was an error

a thing to mention was that before my this issue my pc used to be noisy as in fans wise however now the fans gone very silent i doubt its an issue but could that means that the choice i have put in my bios have been resetted ?

BIOS itself, no since its stored in EEPROM.

 

The simple explanation is the BIOS/UEFI itself doesn't change unless you do a flash, since its stored in EEPROM (read only memory). Changes done to the BIOS/UEFI are temporary overridden and stored in CMOS, which is maintained through a CR2032 battery on the motherboard.

 

If that circuit is grounded or loses power, then those temporary changes stored in CMOS are lost and the BIOS/UEFI reverts back to its default settings.

Does Event Viewer report anything specific? In the System logs, it should show 'critical/error' with a potential cause. Otherwise its quite likely a PSU issue.

it says WARNING - The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID 

i do not know waht it means ? 

i did change my psu like 8 months ago i went from a budget bad one 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.

so i have lots of error and critical which are mostly the same 

 

 

the critical says this 

"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

 

so the error go like this 

"A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Bus/Interconnect Error
Processor APIC ID: 0

The details view of this entry contains further information"

 

 

 

sometimes the processor APIC ID is 15 or 2 ?

The 'fatal hardware error' error was what I was mainly looking to see. I've seen such errors in scenarios where your PSU is flicking off, which could be a number of issues.

 

Based on the condition that likely caused the issue, there's likely an issue with the power supply and/or the outlet. If you're using an outlet with a switch on it, its even possible that the switch itself is now damaged after bridging a heavy load like a computer suddenly.

 

In any case, I would recommend having a UPS regardless for your PC for some of the power conditioning, surge protection, and safer shutdown capabilities in the even you lose power with a heavy load. It may solve your issue if there's some damage in the electrical bus supplying it, in either the outlet or the switch. In the event a UPS doesn't fix it, you're likely looking at a new power supply, but at least you'd then also have a UPS covering it.

 

In my house, my office is where my computer is. The outlet my UPS and therefore PC is on a switch by the door. Its a convenient way to test my UPS but would otherwise be a nightmare if I didn't have one. I started defaulting to a UPS because I used to be active duty right next to a major shipyard where every time they'd start the giant cranes, my PC would flick off. 

 

Regarding finding a UPS, usually the bigger the better. That's not just in the load they can supply but also the repairability, quality control, and features. The 1000VA and higher ones having very functional front LCD displays that you can use as a watt meter and to track events. No need to wire up the RJ-45 or USB either, if you lose power while gaming, you'll have plenty of time to quit the game and shutdown without needing an auto shutdown feature through the data connection. Depending on where your WLAN/router/network/firewall/modem is located, you can usually fit that on there as well. My whole network and PC runs off a 1500VA one as example, so as long as there's internet and I don't feel like using the 4G LTE failover capability of my firewall, then it'll stay up.

hey thanks for the reply 

so i have a main wall socket which i have attached them extnetison cord to attach more than 1 device to it if you know what i mean so for example in this extentsion i plug in my speakers plug, monitor and computer as well as my iphone charger, in short words is a way to power on 4 things using one socket (i do not know what the thing is called), however the power falls its only to the computer the moitor and charging stays on which means that it can be the socket or the extension cord 

is most liekly something inside

 

like i metiod my PC is doesnt really have high end parts and dont really draw much power a 1050 and a r7 1700 and i was told my power supply was more than enough and a good upgrade, is it possible that my power supply is bad ? and i need to chagne this ?
