Windows 7: Bsod driver_iqrl_not_less_or_equal

Hello i have a problem
I get BSOD - blue screen of death 1-2 times a day
I get this message
DRIVER_IQRL_NOT_LESS_OR_EQUAL
and at the bottom of the screen it gives this file usbechi.sys
once i got this file USBPORT.sys but once when i actually paid attention to the given file
I also took a photo with my phone
And i also added the file from SF_Diagnostic_Tool - Grab all
So i hope someone can help me

okay I'm looking at this and before we do anything can you follow the instructions here
SFC /SCANNOW Command - System File Checker

The actual error you are getting is related to your usb driver, or possibly a device plugged in via usb. I'm suggesting the above because several root system files don't seem to have the right tags on them.

I tried but when i do that my bsod appears it didn't finish the scan.
And now I'm from safe mode with networking
and it appears that i can't do it from here
any other advice ?

If you have not already please uninstall Daemon tools. Please also download and run this tool, if the uninstall button is not grayed out click it and let the tool run. DO NOT click the install button it will install a harmful driver that is known to cause BSODs on your pc.

I uninstalled it and i still get bsod
also i got this new bsod one time without a message or file
and the code from 0x00D1 it changed to 0x001E
here is the picture

please run the SF diag tool again so that we can have a look at your new crash dumps.

Here :

PLease Download and run this tool: Duplex Secure when the tool runs click the uninstall button and let the tool do its job wwhen it is done post back and let me know if you continue to have issues.

I cant uninstall it
this is the message i get when i start it

No SPTD version was detected
Select action to be performed

and there is install or cancel,,, the uninstall button is grayed out

C:\Windows\System32\Drivers and see if you can find SPTD.sys it is still listed in your drivers in your crash dump for some reason, if you find it delete it. Next if you could please Enable Driver verifier and let your system crash again, then once the system has crashed (this could take up to 24 hours) Disable Driver verifier run the SF diag again and post the new crash dumps. Here is a tutorial on how to enable and disable Driver verifier:

Driver Verifier - Enable and Disable

WARNING: If you can not boot normally after enabling Driver Verifier please boot into Safe Mode and then disable Driver verifier, you should then be able to boot normally.


Run Memtest86+ for 9-10 passes (TIP: do this overnight it will take hours). Here is a tutorial on how to do that:

RAM - Test with Memtest86+

please post back your results.
