9950X3D Build keeps crashing without bsod

[DrAllesKlar]

Hello,

 

this weekend i built myself a pc, but after 2-3 days of everything working just fine it now started to crash and/or not even getting into windows before crashing again.

how does the crash look? My Monitors just go black, the case fans and cpu fans are spinning and the cpu light of the mobo is on, but no debug led code.

at first it happened after leaving the pc on the lock-screen for a few hours, but it has gotten worse, to the point where im lucky even getting into windows. Is there anything i could do to pinpoint the issue?

 

specs:

cpu 9950x3d

gpu9070xt

psu nzxt c1200

mainboard gigabyte x870e aorus pro

Storage 2x 4tb Samsung 990pro

ram flare x5 64gb (2x 32gb) cl30

cpu cooler noctua nh-d15

 

firmware and drivers: Windows 11 Pro, newest bios (FA3a) and the newest drivers installed via adrenaline and gigabyte control center

 

what i have done so far: 

on the First 2-3 days it worked just fine, no crashes or anything while doing cpu and gpu stress tests. Also played games for many hours on max settings without issues.

then yesterday it started with crashing while playing stellaris and it went bad from then on. 
 

when it first started to get bad i flashed bios again, reinstalled windows, reset cmos but it didnt help.

i tried testing it with expo on and off, both made no difference. All other settings are standard.

i ran memtest86 and prime95 and both times it just crashed mid-tests the same way as stated above. Memtest didnt show any issues (at least not that i could see because of the Crash on pass 1/4)

 

i never saw the cpu hit higher than about 80c, so temps shouldnt be the issue. To rule that out further i tested prime95 on smallest fft starting with 2 cores for a few minutes and adding 2 each time. I got to 6 cores before it crashed. Temps were fine. (Today in the morning it crashed with 2 just after seconds, so i guess its a bit random?)

 

Yesterday night i reseated cpu, made sure there are no bent pins. I was able to do a full gpu stresstest again but it crashed on the cpu test

i can rule out the gpu at least, since it does the same when its not in the system (disconnected and removed). But apart from that i cant rule out anything else myself..

 

when im in bios there are no crashes, but getting to windows from here is pure luck. Also getting into bios is only possible by resetting cmos or through windows recovery. The Buttons (del, F12) dont work.

 

what i noticed with the system is that it wouldnt hit above 80-90% load on the cpu, no matter what stress test i throw at it. The First time i did prime95 on 16 cores i only saw a frequency of about 3.6ghz, but it seemed fine afterwards in hwinfo (5.4-5.5 for full core load).

 

Right now im on the essentials software and drivers-wise to rule that out, so basically only steam, discord, chipset, wifi/bluetooth and gpu drivers)

disabling the auto-start of steam and discord via task manager helped getting into windows more often without crashes, but its not guaranteed sadly.

windows energy settings (balanced and performance) made no difference)

 

im clueless as to what i can do next to somehow pinpoint the issue and maybe start an rma. Because right now it could basically be everything..

any help would be greatly appreciated.

 

i also posted it on reddit yesterday but i hope to reach more people here, since i only got one response there :(

Did you install AMD chipset drivers ?

Hi, yes that was one of the First things i did after (re-) installing Windows. I manually installed them and confirmed they were installed by not seeing it in gigabyte control hub anymore.

Are you saying that the whole PC also crashes during MemTest86 RAM testing?

Yes, thats correct. There were no errors/problems listed (as in 0 issues were shown). With memtest86 there also was no bsod equivalent or anything shown before the monitor just went black and the pc was in this crashed-state again

im a bit late on response, but i think its your ram. try running at lower clockspeed.... it should work.

I agree. 

I recently helped a mate out with his crashing laptop. His laptop made a mixed bag of BSODs and simply hard crashes. I could maybe stay alive for 3-4 minutes max. 

Long story short, it was one of his RAM sticks that died. Bought a new one and installed it, works like a champ again. 

Since the laptop died almost instantly, we were not able to RAM test, so we simply just tried one stick at a time and found it was the 2nd stick.

Hi, thank you for your responses. I tested my ram sticks by first disabling expo again (cmos reset) and testing one stick at a time. The system nearly got through a new windows install onto the second and nearly empty nvme ssd (only games were copied onto there). This was done to rule out driver/windows issues. Im pretty sure it crashed right at the last step where its jumping from the Installation to the normal Desktop. As when i restarted the pc i got into Desktop. The second stick also caused the system to crash. 
to rule out just a dead motherboard ram slot i also performed the test on another slot, but with the same issue.

sadly i did not try to lower the clockspeed further than non-expo speeds.

since i was all* out of things i could do myself i gave the system to a computer Shop where i used to go to have my old systems build. It was my last resort and it still hurts a bit  but for only 25€ i cant complain, as long as they dont mess anything up. Right now im just waiting to hear from them again (they guess it will be the coming monday). And i really hope it was just a lose cable so i dont have to wait for rma. I waited 2 months abroad to build this ;( 

 

*the only thing i didnt check to be honest were the cables headed into the mb for cpu power and on the psu side. I noticed it waaay to late. But im sure they all clicked fully in and i didnt move anything as soon as the system worked.

 

ill try to keep you posted for updates and appreciate any further input

Hi there, just wanted to update you on the current situation. The problem is very weird, the pc shop sadly couldnt find it. Since the issue sometimes takes several hours or a day its "not possible to track down completely". My Cpu on another test bench worked, even with all my parts but just the mainboard swapped it worked. My mainboard with another cpu worked (9800).. So both of my parts (Cpu + Mainboard) work alone, but if you combine them again the issue starts again.

Every single part of my system was swapped with another one from them, also different bios settings and an external windows drive was tested. So all my parts except for the stated are definetely not the issue. Also the newest bios FA5b didnt help..
 

I ordered the same model mainboard via amazon to test it while i send the presumably broken/faulty mainboard away for rma. Sadly when i picked up my system from the shop yesterday they were so nice and put scratches, dents and dirt all over my system. It broke me yesterday tbh. Spent years saving for it, months planning on building it, only for someone to handle it like a toddler, wtf? I will go there again today and hope to speak with the boss/manager on what exactly is going on there and if i will get compensated for it. But even if yes it really hurts in my heart man  Im just a student, saved up for my dream pc and then this sh.t

I will update once again if i can get the system running and if it stays stable for a few days. Just wanted to update in case anyone else ever runs across this issue
 

This is a pic of just my CPU Cooler (The GPU thankfully is okay, but the case is full of scratches and dents, even the cpu bracket?? And just dirt and thermal paste everywhere. When he handed me the NVME Heatsink full of dirt, smudges and hair i lost it

I understand your feelings bro. I hope everything turns out like you want it to. It sucks in the now with a dead system but know that it is not permanent. You will end up with a working PC. You have warranty on new parts. Make sure to test ASAP and use warranty if needed.
