Game Crashing PC getting stuck in boot loop
Need some help diagnosing a really frustrating Apex/EAC crashing issue because I’m running out of ideas.
System:
- Ryzen CPU
- ASUS ROG STRIX B550-F GAMING WIFI II
- NVIDIA GPU (new)
- New PSU
- Windows 11
Main issue:
Apex Legends crashes are causing full system instability:
- black screen
- audio glitch/freeze
- instant restart or full hard freeze
- sometimes Windows boots into automatic repair afterward
- occasionally system gets stuck in boot loops/recovery
Important:
Other games seem mostly fine.
3DMark Time Spy completed successfully.
Temps are normal (GPU around 50C, CPU around 60C).
So this does NOT seem like obvious overheating.
Event Viewer findings:
- Repeated EAAntiCheatService errors:
- “The parameter is incorrect”
- “Invalid argument count”
- Earlier I had a WHEA Logger Event 18:
- Cache Hierarchy Error
- Apex itself crashed with:
- r5apex_dx12.exe
- exception code 0xc0000005
- HWiNFO also crashed once involving nvml.dll
Things I’ve already tried:
- Updated BIOS to latest version
- DDU + multiple NVIDIA drivers
- Disabled overlays/MSI Afterburner/RTSS
- Apex reinstall/verify
- Repaired EAC properly
- Stock RAM settings (disabled EXPO/XMP)
- OCCT stress tests
- Time Spy benchmark
- System restore attempts
- Startup cleanup
The weird part is:
- Apex/EAC seems heavily involved
- but the crashes are severe enough to destabilise Windows itself afterward
At this point I genuinely can’t tell if this is:
- Apex/EAC + DX12 + NVIDIA driver interaction
- motherboard/platform instability
- PSU/GPU issue
- or Windows corruption from repeated crashes
Has anyone had anything similar or found an actual fix?
