I'm struggling with my Omen 35L gaming PC, which has an AMD Ryzen 7 and GeForce RTX 5060 Ti. It suddenly died on me after I exited the BIOS. I was trying to check the PSU health but accidentally clicked the wrong option. After that, I black screened like the system restarted, and when I forced it off, I started getting a series of Blue Screen of Death (BSOD) errors.
Here are the error codes I'm seeing:
- 0xc000021a
- 0xc0000221
- What failed: ntoskrnl.exe
- IRQL NOT LESS OR EQUAL
- DPC WATCHDOG VIOLATION
- MEMORY MANAGEMENT
- Wdf01000.sys
- PFN LIST CORRUPT
I've tried stopping BitLocker from appearing and using my Microsoft recovery key but just get sent back to the BitLocker screen. I'm really lost and need help figuring out what's going on!

To get to the bottom of those BSODs, we need to access the dump files. If you're able to boot into Windows (even in Safe Mode), check for any dump files in C:WindowsMinidump. If you find them, copy that folder to your desktop, zip it, and upload it somewhere like catbox.moe or mediafire. If you don't have any dump files, follow a guide online to set your system to create Small Memory Dumps. That's crucial for diagnosing the problem better.
It sounds like the mod manager itself isn't to blame here. Those stop codes usually indicate corrupted system files or issues with unstable RAM. It's likely that powering off during a crucial phase after exiting BIOS damaged the boot process, leading to those BitLocker prompts. I'd recommend booting into Windows Recovery and trying a Startup Repair first. If that doesn't work, run "sfc /scannow" and then check your disk with "chkdsk C: /f".
To test your RAM, you could physically remove it and put it back in, but it's better to run a diagnostic tool. You can use built-in utilities like Windows Memory Diagnostic or MemTest86 to check for issues. Just make sure your RAM is properly seated first!
