My computer can't work normally now. A few days ago, I logged in my PC and enterred the desktop, the blue screen suddenly happened. I tried to restart the PC several times, but I failed. I enterred the safe mode and scanned the system, the result reported that the PC was safe. I tried to pull out the memory stick and used an eraser to clear the connecting finger. However, it didn't work as well. I even took apart my PC and cleared the computer fan. What the hell should I do now?

STOP 0x0000007E is the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED bug check — a kernel thread threw an exception the OS did not catch. It’s a generic stop code: most often a bad driver or kernel-mode component, but memory corruption, disk problems, BIOS/firmware or recent updates can also cause it. Collecting the crash data (minidump) is the priority before reinstalling. (learn.microsoft.com)

Before wiping or reinstalling, capture and read the dumps. Disable automatic restart so the BSOD stays on screen (or run the command below), then check C:\Windows\Minidump for .dmp files. For quick reads use BlueScreenView (user-friendly) or use WinDbg/!analyze -v for authoritative analysis. (learn.microsoft.com)

Run these safe-mode repairs in order (save important files first): repair the image, check system files, then check disk and memory. Driver issues are a frequent cause — update or roll back video/chipset/network drivers, and only use Driver Verifier if you can tolerate forced crashes (it’s a deliberate stress/test). Example commands to run from an elevated Command Prompt or Recovery console:

wmic recoveros set AutoReboot = False

DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

chkdsk C: /f /r
verifier /standard /driver problematicDriver.sys   # enable (careful)
verifier /reset                                   # disable verifier

Run a thorough RAM test (Windows Memory Diagnostic or bootable MemTest86) and check SMART/drive diagnostics for disk health; reseat RAM and SATA/PCIe cables, test with one RAM stick, and update BIOS/firmware if available. Driver Verifier docs and the SFC/CHKDSK/DISM references explain the commands above and the risks/limitations. (support.microsoft.com)

Tie-ins to thread: ’s suggestion to read minidumps is the right next step; ’s “disable auto-restart” tip will let you read the BSOD; ’s safe-mode/restore idea is useful if a restore point exists; and ’s reinstall worked for him but should be last — back up data first. If dump analysis names a driver (.sys), remove or replace that driver before reinstalling. (support.microsoft.com)

That code is reporting what is normally (and in your case would be ) a software error, likely a driver because the system worked in safe mode. May I suggest that you force another bluescreen and read the faulting module (likely a .sys file), or download a file called BluescreenViewer.exe and load the latest files in Windows\Minidump into it - that will give you the faulting software module.

Try the following:

Boot into Safe Mode, then

  • Click "Start"
  • Select "Control Panel"
  • For View by, select "Small Icons" (or Large Icons)
  • Click "System"
  • Click "Advanced System Settings"
  • Do you want to allow the following program to make changes...? Click, "Yes"
  • Click "Advanced" tab
  • Under "Startup and Recovery", click "Settings"
  • Under "System failure", uncheck "Automatically restart"
  • Click "OK"
  • Click "OK"
  • Reboot computer.

If it successfully boots, you may see an error message which should help you identify what is causing the error.

Hardware incompatibility and driver issues may cause this error. I suffered from this problem a few monthes ago. But I solved it through re-installing my system.
