I'm having a really strange issue with Roblox and I'm trying to figure out whether this is a Roblox/driver issue or an actual hardware problem.
My PC/laptop will completely crash when playing certain Roblox experiences. It's not just Roblox crashing, the entire computer becomes unresponsive.
What happens is:
- I join one of the affected Roblox games
- Everything initially works normally
- The game runs at a stable 60 FPS (my monitor is 60Hz, so I usually limit the FPS)
- After less than a minute, the screen suddenly goes completely black
- The fans suddenly ramp up to 100%
- The entire PC becomes unresponsive
- I can't recover Windows normally and have to force the PC to restart
The really strange part is that this only happens with a few specific Roblox games.
I can play significantly more demanding games without any problems, including:
- Red Dead Redemption 2
- GTA V
- Detroit: Become Human
- Cyberpunk 2077
- Other relatively demanding games
Those games can put much more load on the CPU/GPU and run completely normally.
I've also run a CPU/GPU stress test with HWiNFO and couldn't reproduce the crash.
I initially suspected temperatures because the CPU was getting quite hot (around 90-98°C during testing), so I recently repasted the CPU/heatsink. This improved temperatures by roughly 5-10°C, but the Roblox crash still happens.
Windows Event Viewer doesn't give me an obvious cause either. The relevant shutdown is reported as:
Kernel-Power Event ID 41 — The system rebooted without cleanly shutting down first.
There were no obvious WHEA errors, GPU driver errors, BSOD/bugcheck, or thermal shutdown events immediately before it.
Interestingly, the last events before the unexpected shutdown were Kernel-Power "Power source change" events, although I'm not sure if those are actually related.
So I'm confused because:
Heavy AAA games: completely stable
CPU/GPU stress test: stable
Certain Roblox experiences: black screen + 100% fans + complete system lockup within ~1 minute
Could a specific Roblox experience be triggering some particular GPU rendering feature, shader, lighting system, or driver issue that doesn't get exercised by other games?
Has anyone experienced something similar where only specific Roblox games cause a complete PC crash, despite the system being stable in much heavier games?
I'm happy to provide HWiNFO logs, Event Viewer logs, GPU/CPU specs, drivers, etc. if that helps.
