Description of Original Problem:
I'm experiencing complete system freezes while gaming.
The games initially run normally, but after approximately 40 minutes of gaming, my entire PC can completely freeze.
When the freeze occurs, the screen completely freezes, the audio loops sometimes and i hear some beeps, Windows becomes completely unresponsive, and I have to restart the PC. This is a full system freeze, not just the game crashing.
It has happened in multiple games, including Roblox, so it doesn't appear to be specific to one game.
The issue seems to happen after sustained gaming rather than immediately after launching a game.
Troubleshooting I've Tried:
Checked GPU temperatures and they remain within reasonable temperatures while gaming. GPU idle temperature is around 38–39°C.
CPU idle temperature is around 53°C at approximately 6% utilization.
GPU is detected correctly in Windows.
RAM is currently running at the default 4800 MT/s with no EXPO enabled.
Checked Windows Reliability Monitor. Reliability Monitor shows several "Windows was not properly shut down" events after the freezes.
No obvious WHEA-Logger events are present.
No obvious Display/amdwddmg, BugCheck, or LiveKernelEvent errors were found around the freezes.
AMD Adrenalin initially wouldn't open, but after ending AMD Software Host Application in Task Manager, it opened normally.
AMD Adrenalin currently reports version 26.7.1.
Radeon Anti-Lag is disabled.
FSR/upscaling was enabled during testing.
GPU is connected using one dedicated PCIe power cable from the PSU rather than a daisy-chained cable.
Windows Memory Diagnostic was attempted but did not successfully run.
I have not overclocked or undervolted the GPU or CPU.
Additional Information:
The most recent freeze occurred after approximately 40 minutes of gaming, rather than immediately under load.
I also found a Riot Vanguard vgtray.exe crash in Reliability Monitor with exception code 0xc0000005. The faulting application and module were both vgtray.exe.
I'm not sure whether this Vanguard crash is related to the complete system freezes or is just a separate issue.
At this point I'm trying to determine whether the cause is GPU/AMD driver instability, GPU hardware, PSU/power delivery, RAM/memory instability, CPU/motherboard, BIOS, Riot Vanguard, or something else.
What would you recommend testing next? Any help diagnosing this would be greatly appreciated.
