Computer shutting down abruptly

[AlexRD]

Hi,

I've been having a very weird issue lately.
My computer has been shutting down from time to time, like if i hit the power cord on accident.

I know its not the temperature because i have checked it, it's always normal.
I tried switching power cables, connecting it directly to the power outlet, but still it happened.

Other than temperature, i really have no idea why a computer would shut down like this.

Anyone have any suggestions? Cause i have no clue where to start

I would start with the PSU.

Do you have another one you could try?

Also check the cable connections from the PSU to motherboard.

Hi, sorry for the delay, but no, i don't have another PSU.
Also the connections are fine

Hopefully one of our experts on this forum will come along with ideas about finding the problem.

In the meantime:

When you push the power button, does the computer start right away or do you have to wait awhile?

Check your bios, at loss of power is it set to stay off? You may want to change the setting to power up when power is restored and see if the computer restarts on it's own. If it does restart, it is either the PSU or your power line to your location. My computers are on a UPS and I am amazed by the number of times I can hear it kicking in even though I don't see the lights flicker.

Is it always when you kick the power cord? (Which end are you kicking)

Actually, my computer is also on an UPS. On power loss, the UPS can hold it for 20 minutes i think. So i don't think the power line to my location is at fault.
I'm going to check my bios now

No, it happens sometimes while i am not even in the room.

Can I ask you to download this: Prime95 (32bit) - 25.11 Download - EXTREME Overclocking it is a stress tester - I'm looking at CPU load in this instance (humor me). Run this through default settings, so literally click through, give it a few minutes. Close it if you're still alive - if its died then you may have a badly seated heatsink (you might've knocked it loose when kicking it around)

I've seen this first hand on two occasions

Temperatures of particular components might be ok but sometimes the small elements start the problem like these.... like those big capacitor on mobo ........... CHECK them sometime they swell and create the problem u r having >>>

I think i fixed my problem. I went in the BIOS and i resetted everything to default, and re-configured it. Apparently, its now working.

Now that i come to think of it, i remember disabling BSODs so that the computer would shut down instead of dumping to memory. And i was undervolting my CPU by a small amount. Thats why i didn't know. I think .

Nevermind that, it was all wrong.
It started shutting down again 8 hours after that.

I tried prime95 out for a few minutes, but it didn't shut down.
Any suggestions?

This is still happening. I have no clue on how to fix this.
I even did some google research, but most people that have this problem actually have overheating problems.

I did find, however, that whenever my computer crashes, i get a WMI error in the event log. Not sure how those are related.

This is what it says:

Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.

HI Alex,

I have found a link which may help you in solving the problem related to your event log.Give it a try.

Event ID 10 error every boot

 

[AlexRD]

Now that i check it again, the WMI error is doesn't coincide with the restart time.
So i was considering formatting my PC. I really don't want to go through all the trouble jsut to find out that it wasn't the problem.

 

[AlexRD]

Alright. It isn't an OS Problem, as it just turned off on me while i was configuring the BIOS. I am stumped.

 

[Bumpkin]

I was just about to suggest a Repair Install instead of a clean install. But now we know it's not the OS!

Try to reset the bios to default.

Remove any internal or external drives except your boot drive. And disconnect any USB devices.

I still think you need to have the PSU checked out or replaced.
