Windows 10: Need help fixing crashing PC intermittent BSOD's

Hello, Could someone help me troubleshoot my desktop PC? I keep getting different BSOD errors, mainly the followingirql_not_less_or_equalkernel security check failure?0xc000021a0x0bad0011Also seen wdf01000.sys, usbhub3.sys and today I got a "DPC watchdog violation" which is the first time I've seen itI've ran the dell support tool upon boot which tests harddrive, ram etc and it all passed. I've googled these errors and ran a few of the commands suggested sfc, dism and it repaired 2 files I think related to start menu? but the problems still persist. Sometimes it'll BSOD within sec

:)

 

Kernel_security_check_failure bsod


A few months back I built my first PC, since then I've intermittently been experiencing BSOD crashes.

My computer crashes to a BSOD with the KERNEL_SECURITY_CHECK_FAILURE error message but I've also rarely had the following BSODs:

• DRIVER_VERIFIER_DETECTED_VIOLATION
• MEMORY_MANAGEMENT
• SPECIAL_POOL_DETECTED_MEMORY

That being said it's nearly always the KERNEL_SECURITY_CHECK_FAILURE error; the other messages haven't happened more than once or twice each.

I've attached the DM Log but I'm fairly new at this so please let me know if there is any other information that would help fix this.

Help me Ten Forums, you're my only help.

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?

 

GPU-Z 0.8.7 crash on launch

W1zzard is asking you to test so that he can suggest next steps and be able to troubleshoot the issue you have.
If another version works, it would be one set of steps.
If several other versions also fail/crash, then it would be another.
