weird freez issue after upgrade
Hello, everyone, I need your help
I recently upgraded my Mobo, CPU, and RAM on a system that was previously rock-solid. Ever since the upgrade, I have been experiencing frequent, random system freezes and sudden restarts. I am almost certain it is a hardware issue, but I am completely stumped on which component is causing it.
Here are my specific specs, comparing the previous stable setup to the current unstable setup
I used to have a B450 Aorus Elite, Ryzen 5 3600, and 8x4 32 GB DDR4 RAM running at 3600
An RTX 4070 Super PNY XLR8 3 fans and Alpha Furry GD 850 w 80+ gold psu
Now I have B850 Aorus Elite, Ryzen 5 7500x3d, and 1x32 cl30 32 GB DDR5 running at 6000, and everything else is the same
When the system is almost completely idle or under load , it frequently freezes entirely. The mouse freezes, the screen stops, and the PC becomes completely unresponsive. I have to perform a manual hard restart via the case button. There are no debug LEDs active on the motherboard when this happens. or sometimes this freeze happens and the system restarts on its own with no error in windows
Since i reused the PSU and GPU on the old B450 system and it was perfectly stable, I have largely ruled them out as defective, though I wonder if they are struggling with new AM5 power interactions.
I found several software-level errors using Windows reliability history and Device Manager
usb crash log Windows recorded LiveKernelEvent 144 crashes. The specific dumped file pointed to USBXHCI.SYS. This suggests the fatal freeze happens when the motherboard’s USB controller crashes.
Device Manager shows a recurring error for a BillBoard Device. I do not have a USB-C hub plugged in but i have the g9 samsung monitor and it has a usb hub which i used with the old B450 setup . This looks like an internal USB connection or port is shorting out and spamming the system with errors until the kernel panics.
i have tried several things and nothing worked but here is what i tried
clean win install The very first thing I did after the upgrade was a full wipe and fresh install of Windows.
stress test The system a 1-hour combined OCCT load test stressing CPU, GPU, and PSU without errors. This makes me suspect the instability is related to low-power idle voltage management or rapid transient power spikes the PSU can't handle but as i said before this psu is fine with the old B450 sytem .
The problem happens whether EXPO on or off and i ran the windows mem test tool with Expo on and off with no errors
evrey driver like chipset and gpu are up to date the temps for all components are within the normal range the bios is the lastest version
idk what to do please help
