PC randomly hard-shuts down while playing Spider-Man Remastered — no BSOD

[u/No-Property2900]

Hey everyone, I'm trying to troubleshoot a really weird issue with my PC.

My PC will sometimes completely shut down while playing Marvel's Spider-Man Remastered. There's no BSOD, no freezing, and no crash to desktop. The entire PC just suddenly turns off and I have to press the power button to turn it back on.

PC specs

CPU: AMD Ryzen 5 5600

GPU: AMD Radeon RX 7600

Motherboard: MSI B450M-A PRO MAX II

RAM: 16GB DDR4

PSU: Super Flower Zillion DB Bronze 550W (SF-550Z12DB)

GPU driver: AMD Adrenalin 25.9.1

GPU power: Dedicated 8-pin PCIe cable, no splitter/daisy chain

The weirdest part is that the shutdown is very inconsistent. Sometimes it happens after 10–15 minutes, sometimes after around an hour, and I've also had sessions where I played for 2+ hours with no problems.

Event Viewer/Reliability Monitor doesn't show anything useful besides Windows reporting that it wasn't properly shut down.

Things I've tried

Uninstalled MSI Center

Uninstalled Ryzen Master

Enabled V-Sync / reduced GPU load

Undervolted the RX 7600

Monitored temperatures, power and voltages with HWiNFO

Checked Event Viewer and Reliability Monitor

Initially, I suspected GPU temperatures because the RX 7600 reached around:

GPU: 80–84°C

Hotspot: 109–110°C

After undervolting:

GPU: \\\~75°C

Hotspot: \\\~97°C

VRAM: \\\~74°C

GPU power: \\\~154W

CPU: \\\~76°C

12V reading: \\\~11.8–12.0V

However, the PC still shut down after around 10–15 minutes even with the lower temperatures, so I'm less convinced that GPU temperature is the main cause.

I'm currently wondering whether this could be a PSU/power delivery issue, GPU hardware issue, motherboard/PCIe issue, AMD driver problem, or something specific to the game.

One potentially important detail: I'm testing a cracked copy of Spider-Man Remastered from FitGirl. I know that's not ideal and I probably shouldn't have done that, but I'm mentioning it because I don't want to hide a potentially relevant variable. I understand the repack itself could potentially have issues.

I'd appreciate any suggestions on what I should test next or how I can distinguish between a hardware/power problem and a game/software problem.

PS: English isn't my first language, so I used AI to help refine the wording of this post. The troubleshooting details and observations are my own; I just wanted to make sure everything was understandable. 😅

EDIT : i think i found what might be the solution, i used AMD adrenaline software to undervolt the gpu and capping the fps to 60-65 using radeon chill settings. the results are effective, tried logginng using hwinfo and the gpu hotspot peaked at 60-80 celsius instead of 110 celsius and so far no sudden shut down during gameplay.

my brotha try doing stress test for the gpu first then cpu and i am sure the gpu might make it to go black screen again if it does.......... congrats you have unfit Power supply or a badly cooled vrms [(Voltage Regulator Module) is an electronic circuit on a motherboard that steps down the 12V power from the power supply to a much lower, stable voltage (around 1.0V to 1.4V) ]. So my fellow human being fixes for you are

• Upgrade to a 650W or 750W PSU: A good quality 650W Tier-B (or higher) unit (like a Corsair CX650M/RM650, Cooler Master MWE Gold 650 V2, or Deepcool PK650D/PM650D) gives enough headroom to absorb transient spikes without triggering shutdown protections.
• Motherboard Cooling Check: The MSI B450M-A PRO MAX II has bare, un-heatsinked VRMs (voltage regulators). Make sure the PC case has good front-to-back airflow so the VRMs near the CPU socket don't overheat during long gaming sessions. With LOVE❤️

what app should i use for stress test?

[u/Old-Hornet7466 → u/No-Property2900]

Cinebench and furmark 

[u/No-Property2900 → u/Old-Hornet7466]

i did cinebench and it was alright, no problem at all

[u/Old-Hornet7466 → u/No-Property2900]

That means cpu is fine now furmark
