int8 model cause PC crash

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

.

### Actual Behavior
RTX3090
Python Version 3.12.12
2.9.1+cu130
I have recently started using the int8 model, which was able to function normally for the first two days. However, after the first computer crash with a blue screen, it started crashing indefinitely.（Maybe upgraded comfyui ver during this period）

At first, it was thought to be a hardware issue with the computer, but later it was discovered that switching to FP8 would work properly.

When using the int8 model, the graphics card does not load the model response, and the usage rate of the computer SSD reaches 100%, followed by a blue screen crash.

### Steps to Reproduce

### Debug Logs

```powershell
.
```

### Other

_No response_

No source file, test, or usable debug log is provided. Start by reproducing the failure with the int8 model on an RTX3090 under Python 3.12.12 and ComfyUI 2.9.1+cu130, compare it with FP8, and isolate whether custom nodes affect it. Done means the cause of the blue-screen crash is identified and the issue has a verified fix or a documented project-level limitation.
