Frequent system freezes (no BSOD) on new pc

Megahertz said:

DDR4 runs at default 2400 MHz. To run at 3200 it has to be overclocked. On Intel MB it calls XMP (Extreme Memory Profile) and it is set on BIOS.
If I were you I would reset BIOS and load defaults, (AMD Ryzen 7 5800X at 3.8 - 4.8 GHz) and let it adjust the core voltages.
What was the temperatures you were reaching with defaults voltages?
Ryzen-7-5800x

I was reaching up to 65C in idle and 91C(throttling) in gaming and benchmarks. Although it was basically a heatstroke where i live at the time, ambient temps have since gone down + i installed another case fan so the temps have decreased since (cpu temps in load are now down to like 70c, GPU still runs hot though at around 85c)

I didnt do any changes in BIOS afaik, i undervolted in ryzen master. I can try reset BIOS of course (at this point im about to send all the parts back anyway, pc is not useable at all in this state) but iirc, I had these freezes from day 1.

On the invoice the memory is named
HyperX 64GB (2x32GB) DDR4 3200MHz CL16 Fury
but when i look in bios it says memory frequency 2400mhz capacity 65536 MB
so i guess you're right it doesnt run in the advertised speeds unless OC'd (which I havent, i've done no such changes in bios that i can recall).

i'm not even sure how to reset bios, checked around for some factory reset but there isnt any.

CPU and GPU temperatures should never go above 80ºC.
- Is the CPU cooler well installed over the CPU?
- Do you have liquid coolers?

All MB sets are done in BIOS. Ryzen master probably change BIOS settings.

It's well installed (I even reinstalled it and replaced thermal paste) it's only air coolers, no liquid. Why 80c? That sounds much lower than what i've read elsewhere. I'm almost always above 80C on GPU when gaming...



But I'm 99,88% sure that this is not related to heating issues. Yesterday I played a 12 hour long session, not a single freeze or any issues encountered. Today I've had 4 system freezes, 3 of them while AFK, 1 while semi afk (working with another computer right next to this one, was afk for maybe 5-6 minutes and it froze that time).

Ryzen Master reverts to default settings (i.e very high voltage output and high core speeds) upon restart (which I have a lot of due to these freezes).

I've had these freezes with both stock settings and my undervolt profile.

After updating BIOS last night, I attempted to recreate the latest crash, which was really just putting spotify on and going afk. About 4 hours later the PC was still running and had not frozen, so went to sleep. This morning, I found that the screen was black and the pc was completely unresponsive. This was different from before, where it would freeze in windows, but I could move the mouse.



After rebooting also, the background wallpaper suddenly disappeared and was replaced with just black (not in safe mode).

Try a Repair install.
Run setup.exe from a Win 10 installation drive or mount a iso file and run setup.exe.
It will reinstall Win 10 keeping your programs and data.

I've tried this, but the issues persist

PC didnt freeze during 5 hours of afk. I got back home and browsed the news for 45 mins, then went afk for 1 min - it froze. The only thing I noticed before it froze was that all programs using internet stopped responding - then explorer, then entire pc (happens within like 30-60 seconds). This time my mouse cursor was not visible and could move around like before.

When reseting and rebooting, my desktop wallpaper was gone and instead was all black. After about 1 min, the wallpaper came back.

Do you have wireless keyboard?

No, only headset is wireless

The freezes keep happening. I tried to not run the undervolt profile (read somewhere that undervolting can cause freezes when in idle, even though it shouldnt) and while the pc ran for a bit longer in idle without freezing, eventually when I got back from afk, the monitors were black and the pc was completely unresponsive?

I guess no one can help?

This thread died a long time ago, but on the off chance that someone still reads, this is the update:

After trying everything I could think off, I turned the pc back to the place of purchase. They ran several tests (both stresstest and leaving the pc in idle) without encountering any freezes. They suggested that I bring in all peripherals so they could connect them and see if the issue was there, which I did, but still, nothing.

After a couple of weeks I got the pc back, as they stated they had not been able to replicate the issue and therefor were unable to replace any hardware (i still dont know if it is hw or sw causing this myself).
It ran fine (only differences I could notice was they'd install w10 home oem instead of w10 pro which I had, and also a lot of bloatware that came with the drivers..) for several days, until today, when I got the exact same freeze again:
I'm watching youtube, when suddenly the video begins to buffer. I reload the browser, try another video but nothing works. Moments after, the entire pc becomes unresponsive (could not even move the mouse cursor). I tried disconnecting all usb devices, tried ctrl+alt+del, alt+f4 etc. But only a hard reset would get it out of that frozen state.


One thing I noticed upon restart (not sure if this related or just a coincidence) was that the internet connection was actually down. Issues on ISPs end. Now i'm wondering, desperate as a iam, if these issues could somehow be network related. While a long shot (and especially since, the other 40+ freezes I had the first month, there were no network issues) that would still explain why the place of purchase had no such issue when they had the pc in for troubleshooting.

Check your power supply circuit,in particular the integrity of the wall socket.
If the power consumption/demand on that circuit is high,then the protection measures used on the pc will operate to save the devices..
Your post 19 gives the home versus factory power supply as the only distinguishable difference.
