I'm trying to troubleshoot a friend's PC that's experiencing frequent blue screen crashes. The errors vary, but here are the main ones I've noted:
- IRQL_NOT_LESS_OR_EQUAL (ntoskrnl.exe)
- KERNEL_SECURITY_CHECK_FAILURE (0x139)
- APC_INDEX_MISMATCH (0x1)
I detailed my troubleshooting steps in a forum post, but haven't received any responses after several days. My friend needs her PC back for work, so I'm looking for any insight. I've reviewed the event logs, and it seems this issue has been ongoing for a while, coinciding with several Windows updates. There haven't been any hardware changes, and everything in Device Manager looks normal.
I've also obtained a small memory dump if anyone can guide me on how to share it. Any help would be greatly appreciated!

You've got a couple of minidumps available, but it looks like the system hasn't been making the smaller ones recently, which is strange. This may indicate a memory issue. It's worth checking how much free space is on the system drive as it can affect dump creation. To isolate any bad memory, try running the system with just one RAM stick installed at a time. This approach often reveals if a specific stick is failing.
To get a better understanding of the BSODs, you'll need to gather the dump files. If you can access Windows or boot into Safe Mode, check the folder C:WindowsMinidump for any crash logs. You can zip this folder and upload it to a file-sharing site like MediaFire or Catbox. If you’re unsure, there's a guide on setting up your system to create small memory dumps which could help. Having a few dump files would definitely assist in pinpointing the issue.
