Issue: [Bug]: My PC reboots when I activate Hires.fix
Labels: asking-for-help-with-local-system-issues

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What happened?

My PC reboots when I activate Hires.fix
My SD runs excellent for generating for text2image or img2img and many  extensions.
But in txt2img, when activating Hires.fix with any upscaler or option, when click in Generate, my PC reboots immediately.
I have a PC HP Z640 64RAM Graphics Card RTX 3080 Ti. 
Latest video driver, 531.61-desktop-win10-win11-64bit-international-nsd-dch-whql
If I send Text2img picture and send to extras, I can upscale correctly without problems.
Video RAM runs at the half capacity in text2img 512x768

### Steps to reproduce the problem

Checkpoint revAnimated_v11.safetensors [d725be5d18]
VAE vae-ft-mse-840000-ema-pruned.safetensors
Noise multiplier for img2img = 1
DPM++SDE
Steps = 20
512x768
CFG Scale = 6
It generates an excellent picture in 2 seconds
But if same setting I select Hires.fix, my PC reboots



### What should have happened?

Generate an upcaled picture without rebooting PC
