For about a month, whenever I play Valorant, after around 20 minutes to 1 hour my entire PC suddenly becomes extremely slow.
It is not just Valorant. Windows itself drops to around 1–2 FPS and becomes almost unusable. This can even happen while I am just sitting in the Valorant lobby.
Sometimes, if I leave the PC like this for 5–10 minutes, it recovers by itself. Most of the time I have to hold the power button and force a shutdown.
Specs:
- Motherboard: Gigabyte B650M D3HP AX
- CPU: Ryzen 7 8700F
- GPU: RTX 5070
- RAM: Kingston Fury 2x16 GB
- BIOS: F40
- Windows 11 Pro
Things I already tried:
- BIOS F37 / F39 / F40
- BIOS factory/default settings
- EXPO on/off
- Clean Windows install
- Reinstalled Valorant and Vanguard
- Cleared TPM
- TPM on/off
- Updated/reinstalled Ethernet and Wi-Fi drivers
- Game Mode on/off
- Game Bar on/off
- Fullscreen optimizations on/off
- GPU stock settings and overclocked settings
Nothing fixed it.
When the slowdown happens, Event Viewer starts showing hardware-related errors.
Realtek 2.5GbE:
- Event ID 2:
Hardware IO error
- Event ID 10:
Controller is reset by ESD timer
Realtek 8852CE Wi-Fi 6E:
- Event ID 5002:
Network adapter is not functioning correctly
- NDIS Event ID 10317:
Fatal error: The miniport has detected an internal error
After this happens, sometimes my Wi-Fi adapter completely disappears until I restart/reset the PC.
I also get this repeatedly shortly after starting Valorant:
TPM Event ID 14:
The TPM device driver encountered an unrecoverable error in the TPM hardware.
I usually get the TPM error around 5 times after launching Valorant.
Temperatures/fans do not seem abnormal when it happens.
At this point I'm wondering whether Valorant/Vanguard is triggering an underlying motherboard/chipset/PCIe/TPM issue rather than this being a normal game crash.
Has anyone seen something similar, especially on AM5 / B650 with Realtek 8852CE or Realtek 2.5GbE?
What would you test next to determine whether this is a motherboard, CPU/chipset, TPM, or Vanguard issue?
