Question PC freezes completely at random times ?

[ZaptCell]

Hello and Good Year to All,

First please forgive my English. It's not my natural language so i'm sorry. I will try to do the best.

I have a strange issue with my PC.
On Christmas i have purchased a few parts for upgrading my PC.
-a new CPU: (i7-12700K)
a few NVMe SSDs
and a new Mobo ( TUF Z690 PLUS WIFI D4)

So , i have built my new RIG. And after few hours somes issues are occured.
- Somes weird sound on my speakers and my headphones (like static noises radio)
-My USB ports who disconected and reconected randomly
- and the most "important" : my PC freeze completely ( all the system even the RGB lights ).

At the begining i thought my mobo was faulty and i have returned it and buy another one. But i have exactly the same issues with the new one. And i have tried on both W10 and W11
When i had to wait to my new mobo i have installed my old one (z390 ASUS ROG) and not a single issue has occured.

I almost sure now it's not a hardware issue. Because i have test the PSU,GPU,CPU, RAM ans storage and nothing wrong. But it becomes verry stressful to "wait" when my pc will freeze again.

I know this isn't much info to solve my issue but this is all i have gathering like info to post my problem here.

So i hope maybe somes peoples here have a info from me to resolve this , because i must admit .... i do not know what the issue is.

Thank You and again please forgive my Bad English.

SPECS:
TUF Z690 PLUS WIFI D4
I7-12700k
RTX 3090 TUF OC
32GB RAM DDR4 3200MHZ
PSU Antec 850W Gold

My system completely hangs 2-3 times per week. PC is on about 50 hours per week. It may happen at any time, even when CPU is almost idle.

My specs are:
BIOS 1003 , all BIOS settings are default, no overclock, no XMP
asus tuf gaming z690-plus d4
i9-12900k
No discrete GPU
64 GB GSKILL DDR4
1200W Thermaltake

I believe there could be some issues with BIOS stability. Hope next BIOS releases could fix this.

Thanks for your answer .
I have installed the last BIOS update yesterday. I hope it will help this.

Do you have the USB issue as well ? Or just the freeze part ?

Just freezes

You are "lucky" then . Joke aside ,for now the new BIOS seems right. I have minor improvements on benchmarks scores since the update.
