PC Freezes After 10–20 Minutes of Streaming (RTX 5070 + 7800X3D + B650)

[Derek99]

Hi everyone,


I have a serious issue that I can’t solve despite many attempts. My PC completely freezes (no mouse, no keyboard, forced hard reboot) after 10–20 minutes of streaming, whether I use OBS Studio or TikTok Live Studio.

The crash is not immediate — it happens after some time, and there is no error message at all.

️ My system specs:

• CPU: AMD Ryzen 7 7800X3D

• GPU: NVIDIA RTX 5070 12GB

• Motherboard: MSI MAG B650 Tomahawk WiFi

• RAM: 32GB DDR5 6000 MHz (Corsair Vengeance EXPO CL36)

• SSD: NVMe Gen4

• PSU: (can provide details if needed)

• OS: Windows 11

• OBS: version 32.0.2

• Capture card: Elgato 4K60

What I have already tried (without success):



✅ Updated BIOS → version 1.00 (24/06/2025)

✅ Forced PCI_E1 slot to PCIe Gen 4.0 (disabled “Auto”)

✅ Disabled Hardware-Accelerated GPU Scheduling

✅ Clean reinstalled NVIDIA drivers using DDU,

 → tested multiple versions including 576.80 (Game Ready & Studio)

✅ GPU and CPU temps are normal during stream (~60–70°C)

✅ No CPU undervolt / no GPU overclock

✅ Same issue with TikTok Studio or OBS alone (no game running)

❌ The issue still persists:



Full system freeze after 10–20 min of streaming

No BSOD, no logs in OBS

Happens even with a simple “camera only” stream (no game)

❓ My questions:

• What else can I test?

• Is this a known issue with the RTX 50xx series (especially 5070)?

• Is there any beta BIOS from MSI or NVIDIA hotfix driver for this?

• Could it be related to the B650 chipset or PCIe stability?

• Is there any long-session NVENC bug still not fixed?



Any help, advanced ideas, or advice would be greatly appreciated.

Thanks in advance!

If the whole machine freezes and requires a reset, it's usually a hardware or driver error. Make sure you have the proper and up to date drivers for your motherboard from the driver vendor website as well as for other hardware such as graphics card. If the drivers are ok and the issue persists, it's a hardware error.

Generic advice for this case (seems you did some of these): revert overclocking, check overheating, do memory test, update BIOS, check RAM, expansion card and cable seating. It's also possible hardware has become defective. If it never worked before, there might be some incompatibility between components or insufficient power supply.
