Before You Start (Important)
If your PC is stuck in a boot loop:
👉 Boot into Safe Mode
- Restart → Hold Shift → Troubleshoot → Advanced Options
→ Startup Settings → Safe Mode
✅ Step-by-Step Fixes (Follow in
Order)
1.
Run System File Checker (SFC)
Corrupted system files are the #1
cause.
Steps:
- Open Command Prompt (Admin)
- Run:
sfc
/scannow
What
it does:
- Scans and repairs corrupted Windows files
👉 If errors are found and fixed → restart immediately
2.
Run DISM Tool (Advanced Repair)
If SFC doesn’t fix it, go deeper.
Steps:
Run these commands one by one:
DISM
/Online /Cleanup-Image /RestoreHealth
Why
this matters:
- Repairs Windows image (backend system files SFC depends
on)
👉 Then run SFC again
3.
Check Disk for Errors
Disk corruption = silent killer.
Steps:
chkdsk
/f /r
Press Y → Restart
What
it does:
- Fixes bad sectors
- Repairs file system issues
4.
Update or Rollback Drivers
👉 Drivers cause majority of BSODs
Focus
areas:
- Graphics driver
- Network driver
- Storage controller
If
error started recently:
- Rollback driver instead of updating
Steps:
Device Manager → Right-click device
→ Properties → Driver → Roll Back
5.
Remove Recent Windows Updates
Sometimes Windows updates break
things.
Steps:
Settings → Windows Update → Update
History → Uninstall Updates
👉 Remove latest update and test
6.
Run Startup Repair
Steps:
- Restart → Advanced Options → Startup Repair
Use
when:
- System won’t boot properly
7.
Scan for Malware
Malware can kill system processes.
Use:
- Windows Defender (Quick + Full scan)
8.
Perform Clean Boot
This isolates software conflicts.
Steps:
- Run msconfig
- Disable all non-Microsoft services
- Restart
👉 If issue stops → one of your apps is the problem
9.
Reset Windows (Last Resort)
If nothing works:
Steps:
Settings → Recovery → Reset this PC
Choose:
- Keep files (recommended first)
🔍 Common Variations of This Error
You’ll often see this error linked
with specific files:
- CRITICAL_PROCESS_DIED (wininit.exe) → System initialization issue

🚀 Pro Tips (This is where you beat
others)
- Always run DISM + SFC together (not separately)

problems)
- Use official manufacturer drivers only
- Keep Windows updated—but not blindly (watch for issues)
❌ Mistakes to Avoid
- Ignoring disk health
- Reinstalling Windows too early
- Installing cracked software (huge BSOD trigger)
