Hi everyone,

I'm running into an issue where my Acer Predator laptop crashes during any gameplay session with a BSOD (0xc000021a) error — usually a few minutes after launching the game.

The crash happens consistently across all games, including:

  • Roblox (lightweight)
  • NBA 2K25 (more demanding)
  • And several others

So it's definitely not game-specific.

Here’s a full list of what I’ve already tried:

  • Ran sfc /scannow – no integrity violations
  • Checked drive health with CrystalDiskInfo – all good
  • Undervolted CPU & GPU – temps stay within safe range
  • Verified game files
  • Reset Windows 11
  • Updated to the latest BIOS
  • Installed latest drivers for all components
  • Rolled back to older GPU drivers (clean install)
  • Cleared temp/cache files
  • Reapplied thermal paste to CPU
  • Plenty of free storage space
  • Changed power plans (balanced, high performance, etc.)

Despite everything, the system keeps crashing with the same BSOD after just a few minutes in-game. It runs fine outside of gaming — no crashes during browsing, video playback, or even stress testing.

Occasionally, after certain Windows updates, the issue goes away temporarily — I can game without crashes for a while. But eventually, the BSOD comes back with the same error code (0xc000021a).

System Specs:

  • CPU: Intel Core i7-9750H
  • GPU: NVIDIA RTX 2060
  • OS: Windows 11 version 24H2

Much appreciated if anyone can help me out — thank you in advance!
