Hey,

my 3 years old computer suddenly started randomly freezing, sometimes ending up in a DPC Watchdog Violation BSOD, mostly not reacting at all anymore. No Hardware was changed, no additional software installed, no windows update installed recently when the error started to occur. Happens with or without any cpu/gpu load, even while clicking through windows menus or browsing. I updateed drivers, chipset, BIOS, formated both SSDs and clean installed Windows, still happens. Temperatures are low for every component. What else can i try?

EDIT: one of the BSOD dumps:

Full system specs, as well as model and age of PSU?
AMD 5900X
ASUS ROG Dark Hero
GSKILL TridentZ Neo DDR4 32GB
Bequiet 1200W Dark Power Pro (3 years old)
MSI 3080 SuprimX
2x Samsung 980 Pro 500/1000 GB

i removed the auto overclocking from RAM and CPU and let them run at base clock, still happens.
While typing this it froze again.

If you can, go to startup settings> restart and select safe mode. If it doesn't freeze in safe mode then chances are it is some form of driver issue. try uninstalling GPU drivers with DDU in safe mode and reinstall them.

It just froze in basic safe mode (no Internet Connection) without display drivers installed

Would it be more likely that the one currently used for windows is the mischief?
yes, so disconnect that drive and install windows on the other one as well as all the programs you normally use. (this is so that if it is a program that is causing the issue you can identify the program and get rid of it.)

Ill try that, thanks. Currently there is 0 software installed, hopefully its just a semi-dead SSD

I can't believe I forgot, but you should install (if you can) samsung magician to see the drive health to see whether it is failing.
i did that, and it froze while doing the SMART Diagnosis Scan. Tried it once with every SSD, froze both times, but since the magician is installed on the system SSD it still might only be that one at fault.
...Or its something with the chipset or any controller on the mainboard, then i might be f'd.
Both SSDs are still at 100% with no sign of failure, everything in that computer was bought new 3 years ago

okay, its neither one of the SSDs. Physically removed the non System SSD, it froze, removed the system SSD, build in the non system SSD on the slot it was before, tried to install windows and it froze while installing. Thus its neither one of the SSDs nor one of the M2 slots fault :/

Out of curiosity, as I've been experiencing the same exact thing and symptoms for nearly 2 weeks now with a 5950x / Gigabyte X57Os/BeQuiet 12 system, did you happen to have a inpoutx64.sys driver in your PC (c:\windows\system32\drivers\)?

It's like I'm reading my own thread over at the MS forums ( constantly freezing, sometimes with a DPC WATCHDOG VIOLATION BSOD). I ended up doing a Win 11 Reset (kept files), yet it still freezes on both reg and safe modes. Not sure yet if the inpoutx64 driver that's related to RGB software is to blame, but it reappeared after a fresh installation of Win 11.

System freezes like yours would point to a HW issue. It can be any number of things, but high on the list would be the motherboard or RAM.

Do the RAM first, since it's easier (and cheaper) to replace. You can try the software approach: Windows has built-in memory diags. Run that. Then, try some of the popular 3rd-party mem testers.

But thorough mem testing takes a long time. I prefer the HW approach. Assuming you have 2 DDR4 sticks, then chances are if there's a failure, it'll be just one and not both. So, yank one. If BSODs continue, put it back and yank the other one. This will tell you if it's a RAM problem. DDR4 is dirt cheap now, so this would be a preferred outcome.

If not, then we come to the motherboard (I consider CPU failure to be low probability, unless you've been OC'ing all this time, then, yeah, it's a probability). There's not a shortcut here, you need to have a known-good board to swap out.

Edit: But before doing any major transplant, consider first to take system apart, clean everything of dust, then putting it back together. There isn't a completely logical reason for doing this, other than the weak rationale of a marginal connector somewhere being the culprit. But in my long experience of a DIYer, this "clean and hope" method has magically fixed my systems on more than one occasion.

If BSODs continue, put it back and yank the other one. This will tell you if it's a RAM problem. DDR4 is dirt cheap now, so this would be a preferred outcome.
i ran mem check and removed sticks/changed sockets, no help. When it happend for the first time ~2 weeks ago, it was once every few days, now its within minutes after booting windows . Im out of ideas by now. Seems like the hardware is rapidly dying without any clue why or what. I never ran OC except for xmp and PBO, it was always well cooled and dust free

A steadily worsening fault is pretty symptomatic of a HW issue, as a marginal part gets worse.

Since you've gone thru clean Win install step, I assume you've done the rest of the troubleshooting mantra, viz stripped down to bare minimum config, both hardware & software (ie safe mode).

>Seems like the hardware is rapidly dying without any clue why or what

That's not true. All the steps above helps you to narrow down the possible cause by process of elimination. What's left is the board, the CPU, or a connector fault. From most to least likely: connector, board, CPU. So, proceed on that basis, and take everything apart, clean, and put back together.

After that, swap out either the CPU or board, whichever is cheaper and more expedient for you.

Edit: Oops, next step after disassemble/clean/reassemble should be to swap out GPU, before main board or CPU.

The weird part is, i repeated a mem test right now, after it instantly froze within a minute for the last 3 startups, and it went through both leaps without freezing. After the check it booted into windows and i let it idle for 30 minutes, it was working fine after. Then i opened some windows settings and apps, and it froze.
I swapped out the 3080 for a 2080 and it still occured. which part isnt used at all in mem check but in windows? That shouldnt be RAM+CPU+Mainboards core functionality.
it kind of feels like something regarding the drives is at fault, but not the drives themself.
i tried different mouse+keyboard too

What is your ram configuration?
How many ram modules.

Try with single ram module installed.
i think i phrased it wrong, it froze on the last 3 *windows startups* (within 3 minutes of clicking through settings and apps), but the whole memory check went fine when i went directly into it after booting windows.
Im using 4 Sticks, but it also happens with only 1 4 GB stick from a different working computer.
