For the past couple months I've been having an issue, it doesn't happen often (once or twice a month) but it starts with my PC just freezing for 5 seconds and then turning off. It isn't shutting down or restarting, it's almost like a power cut. So far this issue has happened 4 times in the past 2 and a half months. What I have thought about but am unsure if it's even related is I updated my BIOS a few times 2-3 months ago too.

At first I thought maybe it was my PSU (corsair 850w gold), that PSU was less than 2 years old but I decided to change it to a new corsair 750w gold (and yes I used the cables that came with it) about 3 weeks ago. I also got a Cyberpower UPS as I have very dirty electricity and thought maybe that might also be causing issues but the same problem happened again today with the freeze and then loss of power. It happens completely randomly and not when my PC is under any significant load, I only had Discord and a couple of brave tabs open when it happened. I can game and stress test my cpu and gpu with no loss of power or performance, there is absolutely no way I can replicate the freezes and power loss it just happens out of the blue. Also, it isn't a thermal issue either. I keep a very close eye on temperatures and it's not overheating beforehand.

There is nothing in the event viewer except for the PC lost power unexpectantly and there's no crash dumps either, I would assume hardware issues would create logs and dumps too.

What could be causing this? My motherboard is rog strix z590-f gaming wifi with an i7 11700k both of which are just barely a year old. I memtested ram twice and no issues with that.
 
Hello

Give us your complete pc spec's. Also you said it's not a temp issue. Do you know what the temp was close to the shut down ? Prior to all of this , have you installed any new software ?

Temp is usually around 35-45 idle, I have afterburner's temperatures of the cpu and gpu on my taskbar so i can constantly keep track. The temps were in the low 40c when it happened, and around the same temp the other times it happened. So far it hasn't happened when my pc is under any significant load.

No new software has been installed that I didnt already use for years prior and recently I did a full clean reinstall of windows 11 with no change to the issue
 
Are you plugged into any power boards?
What else is on the same power circuit?
Inconvenient But can you move it to a separate power supply line.
not just a separate power outlet but one on a different circuit.

I'm plugged into a UPS that's plugged directly into mains in my room. I'm on the same circuit as my siblings, one has a pc that does not share this issue. This is completely isolated to just my pc.
 
Couple of things for you to do;

Download then run Speccy ( free ) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

You need to enable XMP as the present settings are causing a bottleneck.

There is not one system driver shown to have been installed since Windows was so you would be expected to have issues of some sort, not the computer turning off though, see my canned info below;

Once Windows has been clean installed you must then install first the MBs chipset drivers then the storage/SATA drivers and third the graphics drivers, the drivers can either come from a disk provided by the motherboard manufacturer or downloaded from their site and saved to a flash drive etc, this is a must and Windows should not be allowed to check for updates before it has been done as more often than not Windows installs the wrong drivers or in the incorrect order and this can cause all sorts of problems.

The reason why this procedure is so important, the chipset is what enables the MB to be able to communicate with all the hardware + are the first drivers that Windows looks for on boot.

Change the Windows Power Plan to Balanced, 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.

You should never set anything to turn off on a gaming rig or any computer that is in constant use for that matter.

Driver Booster SkipUAC (Jas)

The above is complete snake oil, nothing should be allowed to randomly install drivers, see my second canned info below;

Once Windows has been installed, you install the necessary drivers for the MB and other hardware and then leave well alone, drivers should not be allowed to auto update and you should never update any driver/s unless the new drivers are intended to resolve a specific issue that you are having, installing new drivers unnecessarily can actually cause you the very issues that any new drivers are intended to resolve and uninstalling the new drivers may not resolve the problem/s that installing the new drivers has caused.

Depending on priority it can take many months before the driver provider releases any fix and depending on the age of the hardware or software concerned they sometimes do not even bother or may have already announced an end of support.

Got to head out for an hour or so but will come back and go through the rest of Speccy and your MTB log.

Noticed that you have Malwarebytes installed but it is disabled, is it the paid for version or the trial and why is it disabled.


Edit to add: Looked at the MTB log and the errors that we can see may be as a result of what has already been mentioned above, as in no system drivers, Malwarebytes etc.

I will mention separately that there is a trusted platform module ( TPM ) issue this relates to the secure boot problem and may or may not be driver related, disable Secure Boot in the BIOS.

Thanks for all the info. I've changed power plan to balanced, I have no idea why there was 20 min hard disk turn off. It's weird because I don't use a HDD but and I've left my pc idle for much longer than 20 min with nothing turning off. Malwarebytes I'll also look into, I think I must have turned it off as a startup app and at the moment it's trial.

Additionally I've enabled XMP. Secure boot seems to already been disabled (Other OS) in the bios. I'm not sure about the system drivers, does this refer to windows updates? I'm not seeing anything.
Windows was clean reinstalled recently as you know but the issue with the power was present beforehand and the same issue happened again after I did the reinstall.

One answer I have gotten elsewhere is it could be damaged power delivery on the motherboard, but it's still odd how inconsistent it is.

Windows 8, 8.1, 10 and 11 come with an improved Windows Defender, it offers the same real-time anti-virus/anti-malware protection as Microsoft Security Essentials. Windows Defender also shares the same malware signature definitions as Microsoft Security Essentials, and Forefront Endpoint Protection. Technically, Microsoft Security Essentials has not been renamed Windows Defender, or combined with it in Windows 8, 8.1, 10 and 11.

Short version, Defender is one of the best AVs and Firewalls and by using only them you are freeing up resources and removing potential conflicts.

Until the drivers have been correctly installed we have no way of knowing whether the fast boot issue is driver related or not, it is clearly flagged up in MTB so there is no denying that there is a problem with it.

Regarding following advice elsewhere, that is frowned upon on forums and for the reasons explained below;

We are always happy to help when we can but we cannot safely do so if you are already receiving assistance on any other forum, doing so may lead to confusion as to whose and what guidance you are following which can be both dangerous and costly, decide on which forum you wish to continue and as a courtesy let the other/s know that assistance is no longer required.

Thank you for your understanding.

Can I ask that you do not quote every reply as we have to read the full post to make sure nothing gets missed,, thanks.
 
Not too sure that I know what you mean, drivers will install where you open them and in this instance you will be opening them from within Windows which by default is assigned the drive letter C:.

You must follow to the letter from where and how you correctly install drivers.
