PC shutdown itself

[uco73]

A few days back the computer shuts down by itself, without any warning and without any trace of it. The BIOS log does not report anything and neither does the event viewer. I have Kaspersky Total Security (paid version). After several hours of scanning, he found nothing. I don't know if it is important to state that the system was installed on 4/6/2021. and until a few days ago it did not cause any problems. Otherwise, the computer shuts down only when nothing is done on it for a long time (15 or more minutes).

1 off could be a service stack overflow (or whatever those are called), also you might need to replace the mobo battery (if you haven't in over 3 years) and push the clear cmos button with power disconnected after battery swap.

More information is needed.

The first question is how old is the actual hardware? Not when you took possession of it or when it was "installed" which is meaningless until you explain what that means.

A quick Internet search indicates that this model was launched nine years ago; I see product reviews from 2013. If your actual unit is from that era, it may be a failing power supply. As oobymach suggests, the CMOS battery might be dead. Replacing a coin battery is certainly the cheapest fix.

When PSUs start to fail, the most common symptom is fluctuating voltage output which can cause unannounced shutdowns.

The next thing is for you to decide whether or not you want to spend the money to find replacement parts (at whatever price they are in your market) in an attempt to diagnose the problem. Dell often uses proprietary parts -- especially PSUs -- so you'd have to locate a replacement specific to your model. And if it turns out the PSU isn't the cause of the problem, you might be stuck with a Dell proprietary PSU that is useless elsewhere.

I have workstation PC. There is no Clear CMOS button on MBO.

PSU is ok. I play games 4-5 hours and for that time I have no problems. I found in Event Viewer that Restar manager shuts down PC. Some KB files (updates) is damaged.

Hi,
Run these with command prompt as admin

sfc /scannow

DISM /Online /Cleanup-Image /AnalyzeComponentStore

DISM /Online /Cleanup-Image /StartComponentCleanup


DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

8x16gb memory
Doubt all the same kit
Try only using the amount of memory that actually came as a kit 2x16gb/ 4x16gb/...
See if the issue repeats.

What does the Reliability Monitor say?

I don't trust Windows 10 22H2 yet

All memory kits are same and OK.

You're right. Ever since the system was upgraded to 22H2, that's when these problems started. I tried to roll back to 21H2 but it won't let me do it because the upgrade was done more than 10 days ago.

Hi,
This points to a sleep or hibernation issue which is usually memory related

Use cmd as admin again and enter below and restart.

powercfg -h off

Might even remove any overclocking you're using atm and see if the issue repeats.

I don't use overclocking. Guys, it's worksation. No overclock possibility in BIOS.

After installing some windows updates my Monitor doesnt go to sleep anymore for some reason.

Hi,
Well I'd say reformat/ refresh install and keep only personal files and don't install all the dell crapware and only reinstall c+++ and necessary gaming stuff.

 

[uco73]

Clean install sloved my problem. I was runing Dell ePSa diagnosis and all tests passed OK. Hardware is OK but system was in very bad condition.

I suggest that you disable the "hybrid sleep" with powercfg -h off (IIRC)
