Troubleshooting bluescreen of death ntoskrnl.exe Windows 7
Had issues with my Windows 7 box got lots of bluescreens, but it happened mostly while I wasn’t around. I came back and saw my computer either being rebooted or hanging on the blue screen.
TLDR; scroll to bottom
Reading the memory dump
Make sure you have enabled memory dumps on system failures. Open System in All Control Panel Items (shortcut Win+Break), then open Advanced system settings in the sidebar.
Select Advanced, then Startup and Recovery -> Settings…. Enable Write debugging information” and select *Kernel memory dump.
On the next BSOD, the current system memory will be dumped into a .dmp file for debugging purposes. This will help in determining the cause of the error.
I use BlueScreenView to view the dumps afterward
All of my incidents seemed to occur within
ntoskrnl.exe. A lot of articles were suggesting issues related to storage and NTFS, but it didn’t really seem like the cause for mine.
- Memory faulty?
- Ran 13 passes of memtest86 without errors
- SATA faulty?
- Switched SATA cables
- Chose a different port on the motherboard
- Switch BIOS settings for on-board devices
- Disabled COM Super I/O
- Disconnected front USB hub (as I’ve had issues with connectivity on those ports)
- Intel system drivers update
- Prevent OS from sleeping
- I was seeing a pattern of when was getting blue screens; either when going to, or waking up from sleep.
- Disabling sleep solved the problems
So preventing my OS from going to sleep solved my problems, and I don’t mind it not sleeping. It’s still turning off the monitors without issues, so I’m happy.
