BSOD bugcheck 0x0000007f (0x0000000000000008, 0xffff9b006236be70, 0xffff818e275eeff0, 0xfffff8076809d9c3)

Hi, just a couple of minutes ago I blue-screened. When I reset, I got the bugcheck "0x0000007f (0x0000000000000008, 0xffff9b006236be70, 0xffff818e275eeff0, 0xfffff8076809d9c3" in event viewer. The only other errors for today on it are about it failing to update Microsoft edge due to not being able to find the update service (expected as I deleted it) and about the server 8CFC164F-4BE5-4FDD-94E9-E2AF73ED4A19 not registering with dcom.
Is this anything to be worried about (malware, system corruption/instability, etc)? I am not very good with tech.
 

Solution
Thanks — that bugcheck can be worrying, but you’ve given the most important piece (the 0x0000007f code). Short answer up front: this is usually not malware; it most commonly comes from a kernel-mode trap that was not handled (usually a bad driver, hardware problem — most often RAM, CPU/overclocking, or firmware/driver corruption), and not a straightforward sign of infection. You should troubleshoot it, but don’t panic yet.
What the code means
  • 0x0000007F = UNEXPECTED_KERNEL_MODE_TRAP.
  • The first parameter 0x00000008 indicates the CPU trap type — trap 8, a “double fault.” That typically means the CPU hit a serious fault while trying to handle another fault. Common causes: bad/unstable drivers, defective RAM, CPU/motherboard...

Common causes: bad/unstable drivers, defective RAM, CPU/motherboard problems, or system file corruption. Less commonly, severe overheating or firmware/BIOS issues trigger it.
Is it malware?
  • Unlikely to be straight malware just from this bugcheck. Malware usually doesn’t produce a trap/double-fault crash like this by itself. Focus on hardware/drivers first.
What to do next (step-by-step, prioritized)
  1. Back up important files now
    • Do this first if you haven’t already (external drive, cloud). Good precaution before troubleshooting.
  2. Check for a memory dump and attach it here if you can
    • Look for minidumps at C:\Windows\Minidump and a full dump at C:\Windows\MEMORY.DMP.
    • In an elevated Command Prompt run: dir /b %SystemRoot%\Minidump
    • If you find files, compress (ZIP) and attach them to the thread — I can analyze them for you.
    • If no dumps exist, enable small memory dumps: System → Advanced system settings → Startup and Recovery → Settings → write debugging information: “Small memory dump (256 KB)” and set the folder to %SystemRoot%\Minidump, then reproduce if it BSODs again.
  3. Run a memory test (high priority)
    • Windows Memory Diagnostic: type "mdsched" → Restart and run. Let it do a full pass.
    • For a more thorough test, use MemTest86 (bootable) and run multiple passes (recommended overnight).
    • Faulty RAM is a very common cause for crashes like this.
  4. Run system file checks
    • In an elevated Command Prompt:
      • sfc /scannow
      • DISM /Online /Cleanup-Image /RestoreHealth
    • Reboot after these complete.
  5. Check disk integrity
    • In elevated Command Prompt: chkdsk C: /f /r
    • It may schedule at next reboot — allow it to run.
  6. Check drivers and recent changes
    • Think about any recently installed drivers, Windows updates, or new hardware. If the crash began after a driver install, roll that driver back or uninstall.
    • Open Device Manager and look for devices with a yellow triangle.
    • Optional: run driverquery /v > %userprofile%\desktop\drivers.txt and attach the file if you want help reviewing drivers.
  7. Test in Safe Mode
    • Boot into Safe Mode (no third‑party drivers). If the system is stable in Safe Mode and crashes only in normal mode, that points to a driver/service.
  8. Check temperatures / overclocking
    • If you overclocked CPU/GPU or if temps are high, revert to stock settings and monitor temps with HWMonitor/CoreTemp. Overheating or unstable overclocks can cause double-faults.
  9. BIOS/firmware
    • If trouble persists, check for a BIOS update from your motherboard maker and reset BIOS to defaults (don’t change voltages).
  10. If it keeps happening after the above
    • Run MemTest86 (full multiple passes).
    • Try removing/reseating RAM sticks and run with one stick at a time (if you’re comfortable).
    • Consider testing with a clean Windows environment or reinstalling Windows if software/driver corruption is suspected.
About the other errors you mentioned
  • Edge update failing because you removed the update service: expected and unrelated to a 0x7F crash.
  • DCOM registration error for a GUID (8CFC1...: usually benign and often unrelated. Not likely the cause of the kernel double fault unless paired with other symptoms.
What I can do for you
  • If you attach the minidump file(s) (C:\Windows\Minidump*.dmp) I’ll analyze them and tell you the most likely offending driver/module and recommended next steps.
  • If you want, tell me:
    • Have you added or changed hardware recently?
    • Did this begin after a Windows update or driver update?
    • Does the crash happen repeatedly or was this a single one so far?
    • Are you running any overclocking or custom BIOS settings?
If you don’t know how to attach the dump, tell me and I’ll give step‑by‑step instructions for collecting and uploading it.
