anything and while normally that's the sort of thing that I would troubleshoot myself I have another problem and that is that if I don't leave to start my vacation in the next 3 minutes my wife is going to absolutely murder me so we're going to call in the Cavalry here dialing a for Anthony uh Hey Anthony uh hello can you fix something for me maybe okay cool my computer's turning off and I got to go man I just got back from vacation and I'm already doing tech support well hey why not come along for the ride and I'll show you my method for troubleshooting barely any information to go off of right after this information for our sponsor thanks to hulman for sponsoring this video Hulk man's Alpha 85s helps you instantly jump start your dead car battery with no Aid required even in up to minus 40° F learn more at lm. g/ hulman minus tells me that he updated the BIOS in order to upgrade to Windows 11 and the computer's been shutting off randomly ever since doesn't matter what he's doing even absolutely nothing let's see if we can track down the issue now the first rule of thumb when doing any kind of troubleshooting always check the most basic Solutions first so we'll start with the wall power and um H actually he's got a UPS down here and I don't think anything else has been turning off randomly like the TV still got power from what he told me so that's probably not going to be our problem that leaves us to the cables which well I'm going to have a hard time getting in under there and you're not going to be able to see that either uh because not only is it kind of dark but the TV is also covering it all up but it looks like the 8 pin 12volt connector looks like it's okay actually there's multiple there and they both look like they're down all the way and the 24 pin ATX connector is also pretty solid there so I don't think that's our problem either now the system has a Threadripper CPU and sometimes over toring the retention mechanism can flatten out the socket's pins so that the CPU is not making contact which can make for a no power on but that doesn't match the description of the issue where it's happening even when the system is idle and besides I don't think I'm going to be able to open this thing up without some help and I'd really rather not do that for now we'll fire it up and move on maybe we'll get lucky first we'll open up a system monitoring tool like HW info and see what our temperatures and voltages look like and we'll also load up task manager to see if any processes are running wild and check to make sure that there's nothing weird showing up in the startup items CPU usage looks okay to me right now we're at 3% with uh only a few things actually being used right now you've got OBS running and uh I guess lonus is doing some idle mining which is fine as long as you are not specifically using your GPU for that as for the temperatures they look okay they're a little high but at the same time we've got a GPU doing idle mining on a closed loop like this or it's not really a closed loop but like it's sharing the cooling between the CPU and GPU and the CPU is currently idling it around uh in the 40s 50s or 60s depending on what's Happening normally depending on the CPU the enclosure and the cooling you have on your system it'll usually hover around 30 or 40 somewhere in there as it is right now I'm not concerned about The Thermals at all it seems perfectly fine to me yeah that's not even all that hot the hot spot temperatures in the 60s so this cooling setup is definitely enough we'll have to find something else that might be the cause of the problem we'll keep these tools open for now so we can keep monitoring it as we use the computer that way if anything does happen we can kind of be tipped off about it before it inevitably shuts down before we move on we should look at the voltages now something to be and bind about software reported CPU voltages is that they're not always correct they can change more quickly than they update on screen so take them with some salt it's also worth remembering that CPU core voltage will go higher or lower depending on the core clocks and what the CPU is doing thanks to load likee calibration a feature that tries to keep the CPU from under or overshooting its voltage range and crashing or potentially taking damage over time this throws a lot of people for a loop because even if you set the voltage manually in the BIOS it's not guaranteed you're going to get that voltage under any circumstances now this is an overclocked Threadripper 3000 so I can't really expect any specific voltage range but I think usually if it's in a low power State you can go from 0.6 all the way up to around 1.4 or more volts depending on the load and while nothing stands out to me right now this is one of the potential culprits for a random blue screen or power off so it's worth keeping an eye on next it's time to see what Windows recorded last time the PC unexpectedly powered off using Event Viewer this is built into Windows just right click on the startup button and go up to Event Viewer here or you can access it by typing this on the command prompt if you're ever really stuck this particular version of Event Viewer has been around since Windows 2000 and is basically unchanged even Windows 11 we'll head over to Windows logs and then system now by default this is sorted by date and time so we'll scroll down to the last time we know what happened and see what Windows sees now I actually already see some things here uh so that's interesting but you can actually tell when Windows was shut down big gap in time followed by three event log items when the service is restarted and if there was a blue screen you'll see some bug check items labeled as critical as well you can use these items to see the blue screens error code which you can then use to narrow things down via Google this PC isn't blue screening so we don't have any bug checks well let us see what else is happening at the time went down and it looks like we have a bunch of acpi events here these are related to power management and that's interesting remember what I said about voltages earlier we might have just found some evidence for it and by the way you'll notice that there are a lot of items in the event log just in general so how do I know that what I'm looking at is what I'm supposed to look at well informational stuff like these things here are usually not that useful unless you're trying to track down something very specific and if you've been fixing Windows PCS for long enough you'll know that some these uh distributed Comm things are usually just there on a fresh install and they're entirely benign if you do want to know what exactly these are referring to though you can copy the string of letters and numbers and search it online or if you're feeling adventurous in the registry this particular one is for immersive shell not exactly exciting or relevant to what we're doing but knowing how to do this can be useful for tracking down misbehaving drivers and services and just knowing about it will help you if a scammer ever tries to convince you Windows is broken by showing you these errors it's a pretty common trap coming back to our main issue we've got a candidate for the problem but we should also check the application log to see if anything wears going on there this is where things like app crashes go and while these don't usually coincide with Windows issues if something specific keeps happening at the same time as a recurring problem it could be related now it doesn't look like there's any patterns showing up here here so we can rule this out for now the security logs aren't usually relevant on single user PCS but they can show you when you've logged in when you've used stored credentials and so on useful if you suspect you've been hacked or if there's a problem with Windows log on but it's not what we're after setup on the other hand are related to Windows updates and a failed or broken Windows update can sometimes do what we're seeing Al be usually with a reboot instead of a shutdown as expected most of this is unremarkable information about which updates have been installed when but a broken update or Windows update service will show errors here for now our best lead is the power management situation by default modern CPUs will enter a low power State when they're not in use called c-states not to be confused with s- States like sleeper hibernation these are like the performance oriented P States you might already be familiar with in the form of turbo boost where the CPU will wrap up its performance in response to load C states are just in the opposite direction now depending on the state the system might turn off some parts of the CPU or Park inactive cores to significantly reduce power consumption and the voltage supplied to the cores and therefore the CPU you can see where I'm going with this right but this is a desktop PC so idle power consumption isn't a major concern therefore let's try turning off C states to do that we'll restart into the BIOS and to do that first I need to stop all of these logging programs and restart the system oh I probably shouldn't have done that while lonus was still like doing stuff but oh well this is how you get into the BIOS usually sometimes you can get into it with F2 and you can get into it through Windows as well if you hold shift while clicking on restart then using the advanced options uh function to select UEFI firmware settings but uh we didn't do that and so I have to mash delete from here we're going to look for C States now some bioses like ASUS's lets you use the search function which we will use but sometimes you'll find it in uh like CPU configuration under Advanced or uh sometimes you'll find it in like power management configuration uh for now we'll just hit F9 to do search and do cstate and it is enabled sometimes you'll see two of them one for Global cstate control and one for c1e or enhanced halt uh if we had that here we would disable it as well for now let's go ahead and disable C States hit uh F10 doesn't work from here okay so F10 to save and reset that's pretty normal and okay if F10 doesn't work on your BIOS for Save and reset you can just go to the um exit screen and it'll ask you if you want to save usually now that we've rebooted how can we know that this worked we can't we can't really test for a random power off event so we'll just need to wait I'll let it go for a few days and then we'll come back to it now thankfully I've got my water bottle from LTD store.com to keep my drink cold till then I'll just add a little bit of ice every now and then all right let's take a look it's still powered on that's a good sign let's see the event log pixel refresher I do not care about you I want to see Windows I don't see any of those acpi events that's a good sign that's really good I think we're good this was happening multiple times per day before and it's been a few days now and it's still chugging along I think it's safe to call this one fixed as for why the problem started happening in the first place well power management has always been and always will be a little bit of black magic a little tweak to how power management works in a BIOS update silicon degradation or even just the Silicon Lottery can affect how stable power management features will be for a given system speaking of which get subscribed because we finally have our last guide you'll ever need for how to build a PC coming up and if you liked this video you'll love that one it's the it's the longest video we've ever done except for the uog back to power management though it's usually fine for laptops because of how tightly integrated the CPU and the logic board are but not so much for desktops with modular components and longer traces many power management features are in fact disabled by default on a

Hardware C states are usually okay but there's a reason you'll see many threads about them on forums going back many many years in this case whatever it was it seems like it was just done luck but it's fixed now and hopefully you'll come away from this video not only knowing that c States can be flaky but also a little more about how to dig in and find out what a problem might actually be and
