Open | Windows New $3,600 PC randomly shuts off when using Adobe programs — getting progressively worse. GPU, RAM or PSU issue?
Hey everyone,
Hoping someone here can help me diagnose an ongoing issue with my PC because it’s getting to the point where it’s seriously affecting my work.
I’m a full-time photographer/videographer and primarily use Adobe Premiere Pro, Photoshop and Lightroom.
Earlier this year, I upgraded from a much older PC to a brand new custom built system. I purchased it in March 2026 from a reputable PC builder here in Australia.
PC SPECS:
CPU: AMD Ryzen 7 7800X3D
CPU Cooler: Thermalright 240 ARGB Liquid Cooler
GPU: NVIDIA RTX 5070 12GB
RAM: 32GB DDR5 6000MHz
Motherboard: MSI B650M Gaming WiFi
PSU: 750W Cooler Master ATX 3.1
Storage: 2TB Biwin M350 NVMe SSD
OS: Windows 11 Home
Case: Cataclysm Voyager Black Tower with 6 case fans
Initial Problems
Pretty much ever since I purchased the PC, I’ve experienced occasional crashes, predominantly when using Adobe Premiere Pro.
Initially, the crashes would happen when doing things like:
- Importing or transferring files in and out of Premiere Pro.
- Scrubbing through timelines.
- Working with larger video projects.
- General editing and playback.
When I say crashing, I mean the entire PC instantly shuts off. No blue screen, no error message, no warning. Everything immediately loses power, including the fans and RGB lighting.
I contacted the PC manufacturer, and after some troubleshooting, they remotely disabled the CPU’s integrated graphics.
This actually seemed to improve things significantly. The crashes became much less frequent, although they would still happen occasionally.
For a while, I just dealt with it because it wasn’t happening often enough to seriously interrupt my workflow.
Recent Problems — Much Worse
Over the last month or two, the problem has progressively gotten worse, particularly over the last couple of weeks.
It’s now happening almost daily, sometimes multiple times in a single editing session.
One of the strangest things I’ve noticed is that closing an Adobe application and then reopening it seems to trigger a complete system shutdown.
For example:
- I’ll be working in Premiere Pro.
- I’ll close the application normally.
- I’ll try to reopen Premiere Pro.
- The entire PC instantly switches off.
- I’ll turn the PC back on.
- If I immediately try opening Premiere again, the PC will often shut off again.
- However, if I leave the PC sitting idle for a few minutes after restarting, I can usually open Premiere without it immediately crashing.
This behaviour is extremely consistent.
It’s No Longer Just Premiere Pro
Initially, the problem was almost exclusively happening in Premiere Pro.
However, recently I’ve experienced the same complete shutdowns when:
- Exporting photographs in Adobe Lightroom (regular Lightroom, not Classic).
- Opening Adobe Photoshop.
- Opening or reopening Premiere Pro.
- Editing and scrubbing through timelines.
- I’ve also experienced occasional crashes outside Adobe applications, although I’d estimate that around 95% of them occur while using Adobe software.
Most Recent Incident
Today, I was doing some relatively intensive editing in Premiere Pro when the entire application appeared to freeze.
My screen then went completely black, but interestingly, the PC itself remained powered on.
After a short period, the display returned, but Premiere Pro was no longer functioning properly. I couldn’t get video playback working.
This was different from my usual crashes, where the entire system instantly loses power.
I’ve also experienced instances where the computer completely freezes, including the mouse becoming unresponsive.
During one of these freezes, I held the physical power button to force a shutdown, but it took approximately 35 seconds for the PC to actually turn off.
Troubleshooting So Far
I’ve contacted the PC manufacturer about the issue previously.
They initially disabled integrated graphics, which significantly reduced the frequency of crashes but never completely eliminated them.
We’ve also performed stress testing on the PC, and everything appeared to run normally without crashing.
Unfortunately, I don’t remember exactly which stress-testing software was used.
What confuses me is that the PC can apparently handle stress tests without any problems, yet something as simple as reopening Photoshop or Premiere can cause it to instantly lose power.
My Questions
I’m trying to work out whether this is potentially:
- A faulty or unstable power supply.
- A GPU or graphics driver issue.
- Improperly seated or unstable DDR5 RAM.
- A motherboard issue.
- Something specifically related to Adobe applications and hardware acceleration.
The instant loss of power makes me wonder about the PSU,
The fact that the system often needs to sit idle for a few minutes after restarting before I can successfully launch Adobe applications is also really confusing.
Has anyone experienced anything similar?
Are there any specific diagnostic tests, Windows logs or hardware checks you’d recommend to help narrow down the actual cause?
The PC is still under warranty, but I’d ideally like to identify the issue before having to ship the entire computer interstate for repairs.
Any advice would be massively appreciated. I’m relying on this computer for my full-time work, and the constant crashes are becoming a serious problem.
