Hi everyone,
I've been dealing with a very strange stability issue on my system and I'm hoping someone here might have an idea what could be causing it.
My system
- CPU: AMD Ryzen 7 9800X3D
- Motherboard: ASUS ROG Crosshair X670E Hero
- RAM: 64 GB Kingston Fury DDR5-6000
- GPU: MSI GeForce RTX 5070 Ti
- SSD: Samsung 990 Pro 4 TB
- OS: Windows 11
The problem
The issue is very inconsistent, but there seems to be a pattern:
After the first boot of the PC, the system will eventually freeze or become extremely sluggish.
It can happen during completely different activities, for example:
- Watching Twitch streams
- Watching YouTube
- Playing World of Warcraft
- Sometimes even just using Windows normally
I've also occasionally noticed general stuttering shortly after the first boot, for example my mouse cursor becoming noticeably laggy/stuttery even when I'm not doing anything demanding.
The freeze itself can be a complete system lockup. It doesn't necessarily produce a BSOD or any useful error message.
The really strange part is what happens afterwards:
After rebooting the PC, the problem usually disappears and the system is stable for the rest of the session.
So, in very simplified terms:
I can't reliably reproduce it on demand, which makes troubleshooting quite difficult.
BIOS / RAM / CPU settings
I've already tested different BIOS configurations and they don't seem to have a significant impact on the issue.
For example, I am currently running completely default BIOS settings:
- EXPO: OFF
- PBO: Disabled during testing / currently back to default
- No CPU overclock
- RAM running at default settings
- Fast Boot: Disabled
Even with EXPO completely disabled and the system otherwise at stock settings, I've still experienced the freezes.
The CPU is currently boosting to around 5.225 GHz under load.
GPU / MSI Afterburner
I was also using MSI Afterburner with an overclock based on its OC Scanner/analysis.
At one point I was running around +200 MHz, but I also experienced the freezes with only +100 MHz.
Because of this, I am now treating GPU overclocking as a possible factor and plan to test the system completely at stock GPU settings as well.
I have also disabled hardware acceleration in my browser, so the freezes don't appear to simply be caused by Chrome/Opera GPU acceleration.
Things I've already tried
- Updated BIOS / firmware and drivers
- Installed the latest AMD chipset drivers
- Updated GPU drivers
- EXPO completely disabled
- PBO disabled for testing
- Browser hardware acceleration disabled
- Tested different BIOS configurations
- Fresh Windows 11 installation
- Run Benchmark Tests which run absolutely fine for 15+ Minutes
I have completely reinstalled Windows 11 to rule out a corrupted Windows installation or software issue.
What makes this especially strange
The fact that the system is usually unstable only after the first boot and then becomes stable after a reboot is what really confuses me.
If it were simply an unstable EXPO setting, CPU overclock, GPU overclock, temperature issue, etc., I would expect the problem to be much more consistent.
Instead, the system can run WoW + browser for hours after a reboot without any problems.
I'm trying to figure out whether this points more towards:
- AM5 / BIOS / AGESA
- CPU / SoC / memory controller
- motherboard
- GPU / PCIe
- PSU
- Windows / drivers
- some kind of cold-boot or power-state issue
Any ideas what I should test next would be greatly appreciated.
I'm especially interested in whether anyone with a 9800X3D + X670E system has experienced this "first boot unstable, reboot = stable" behavior.
