Photoshop randomly shuts of my PC

sameeeee

I have the same issue and Adobe keeps blaming computer hardware. From PCs to Macs, I see this being an issue across a wide variety of their software. Maybe time to get better developers on Adobe's team to actually fix bugs and poor code versus generically blaming people's machines?

Under a modern operating system, an application cannot shut down the operating system and cause blue screens or shut downs.

However, an application can make a call to a driver which can cause an OS error. Similarly, failing hardware can also shut down the system.

Commonly from Photoshop that would be a the GPU driver as Photoshop will use the APIs that other apps might not. However, in your case you describe the issue on saving.

You will need to approach this logically and step through items one at a time to isolate the cause.

1. Make sure your drivers are up to date. Use the GPU manufacturers site for GPU drivers. Use the MB manufacturers site for chipset.

2. Make sure your BIOS is up to date.

3. Is the saving issue to a particular drive? Try also moving the Photoshop scratch disk to another drive. If you do isolate to a drive and it is NVMe make sure the heatsink is properly in contact with the card.

4. Run a utility like Memtest and thoroughly test your system memory. This will also warm the CPU and how any heat issues.

5. Check your cooling. Check your CPU and GPU temps with a utility like HWMonitor.  I had an issue with a watercooling pump a couple of years ago and the system shut down when it exceeded the max temps. Replacing the pump resolved it immediately.

6. If this issue has started after adding extra hardware e.g. additional drives or anything that can draw power, try disconnecting it. If that resolves it, make sure your power supply is adequate to drive your whole system. 

It may take a while, and is a pain to work through, but approaching it in a step by step way is most likely to isolate the issue.

Shutdowns are caused by driver problems or failing/overheating hardware components.

Photoshop may well trigger it by making specific calls to e.g. the video driver that in turn causes the driver to fail. Other applications don't make those calls.

In modern computers, applications are insulated from the system, so they cannot bring the whole operating system down. An application can crash or freeze, but not BSOD or shut down the system. Only drivers can do that.

That looks like a basically safe and solid configuration of components. I've built a long series of computers, and the only time I ran into problems was when I once installed a newer CPU on a slightly older motherboard which didn't have proper BIOS support for it. A BIOS update fixed it, but since then I have always paid particular attention to release dates and component lifecycles.

Start with reinstalling updated drivers, then look at possibly updating the motherboard BIOS.
