PC Restarts Only When Idle

[PeterOz]

could be a glitch with speccy.
Run cmd as admin
powercfg.exe /hibernate off into the Command Prompt. press enter

Normal boot with USB devices removed except my mouse and keyboard didn’t work. I’ve also turned off hibernate via cmd. I’ve also changed my power plan to balanced and will be disabling MSI Afterburner, removing Java, and only using 1 monitor by next boot.

A desktop will fail the power on self test if no keyboard is detected by the BIOS during the POST

The only devices that were plugged in were my mouse and keyboard. Any other USB device was disconnected. PC still restarted while idle.

Yep just noticed my slip there as I should have mentioned that the keyboard must be connected to either a PS/2 port for that type of keyboard and a black USB 2.0 port for that type of keyboard, the faster blue and red USB 3.0/3.1 ports should not be used for a keyboard or booting Windows media from.

Good that you have done what is a must and for as to why explained below;

Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues, the setting should only be used for gaming type notebooks that have a discrete GPU that needs the extra power.

Some other points of note from Speccy and your reply #4;

My PSU is a Corsair CX550M bought last year I think

You really can`t remember when you purchased the most important component in a computer, regardless as even if new the PSU while a good brand the present PSU is too weak for the amount of screens and additional storage devices you have.

The RAM is not appropriate for your CPU, Intel state here up to 2400MHz which means that you cannot enable XMP which is causing a bottleneck.

You have storage space problems and on more than one drive, the partition below is the worst;
Partition 1
Partition ID: Disk #1, Partition #1
[COLOR=rgb(184, 49, 47)]Disk Letter: E:
File System: NTFS
Volume Serial Number: 9C8C456D
Size: 345 GB
Used Space: 337 GB (97%)
[COLOR=rgb(184, 49, 47)]Free Space: 7.46 GB (3%)

For Windows to be able to run efficiently and to be able to update you need to have between 20 and 25% of the partition or drive available on a HDD and an SSD between 10 and 15% as free storage space at all times, if you don`t you risk Windows becoming corrupt or not being able to update which puts you at risk of malware attack.

[COLOR=rgb(184, 49, 47)]Data only storage devices should not be allowed to get any lower than 10% of free storage space of the full capacity of the drive/partition on the drive, this also to avoid data corruption.

Please note that storage devices can physically fail if the amount of free storage space is allowed to drop below the required 10 or 20/25% minimum.

Last but not least, you have enough scheduled updates to be able to choke a gold diggers donkey, nothing but Windows and your AV protection should be allowed to auto check for updates and likewise Windows needs to be asking for your permission before installing them, your Windows Defender should be allowed to update automatically.[/COLOR][/COLOR][/COLOR]

I’ve cleaned up some of my storage. Any idea how to remove/disable any other scheduled updates?

[phillpower2]

You will have to check and deal with each one individually, this will not change the fact that you have a weak PSU having its innards cooked by the demands being placed on it, same goes for the bottleneck caused by the RAM.

Seems to do the trick. Will need further testing, I don’t know if I just ate dinner quickly but it didn’t restart.

[retribution23]

I’ve also done the following:
sfc /scannow
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /RestoreHealth

Update: It doesn’t restart when MSI Afterburner is disabled and Java is uninstalled. I tested with 2 monitors plugged in. @PeterOz any idea where do we go from here?

[PeterOz]

You need to think about a new psu.
One with more power and I would buy a quality one with a ten year warranty gold rated.
The more stress you put on an under powered psu the more heat you cause.
You do not need afterburner.
Do you know if you need java?

[retribution23]

I’ll get a new PSU within this year as I’m due for an upgrade. I just use afterburner for hardware monitoring/FPS for games. I do need java as I still run some jars for downloading here and there.

In the meantime I’ll try to default afterburner settings just to see if I can still run it properly. Thanks for the help!
