BSOD only after normal log in (ntoskrnl.exe+735c0)

D3C3n50r · 13 Oct 2015

Hi,

I recently got a BSOD for the first time and have been getting them since everytime I log in. I have read various forums and have updated all my drivers but the problem persists. I have tried a System Restore but it keeps failing even after I disabled my anti-virus and firewall so I gave up on that. Malwarebytes, Avast, MemTest and almost every other scan suggested to me has not picked up anything wrong.

I'm not sure if these could cause a BSOD but I'll mention them anyway:
- In Device manager I have one yellow exclamation sign next to "Security Processor Loader Driver" under Non-Plug and Play Drivers. Not sure if it has always been there.
- Also prior to the BSOD's I was getting loads of random pop ups from COMMODO HIP asking permission to allow programs to run.

So far i've had 3 bug codes starting with:
IRQL_NOT_LESS_OR_EQUAL (Most frequent)
PAGE_FAULT_IN_NONPAGED_AREA
KMODE_EXCEPTION_NOT_HANDLED

Aside from two of the bug codes all have been attributed to:
ntoskrnl.exe / ntoskrnl.exe+735c0

With fltmgr.sys and cmdguard.sys appearing once.
(according to BlueScreenView)

I have had no problems starting windows in Safe Mode and Safe Mode with Networking.

I've uploaded system info and minidumps below. If you require any more details I will be happy to provide.

Any help will be much appreciated :)

Hi D3C3n50r,

Welcome to the 7forums.

Please test your memory with MemTest86+

Code:

Probably caused by : memory_corruption

Diagnostic Test

RAM TEST

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums

Note

MemTest86+ needs to be run for at least 8 passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Ok after an 18 hour long wait MemTest86+ came back with 0 errors. I'm still getting BSOD after log in.

What is the next step? :)

Please run the tool again and upload the zip file.

D3C3n50r · 14 Oct 2015

You referring to the dump file? Sorry still new to all this.

**axe0** · 14 Oct 2015

I am referring to the tool you can find in the BSOD Posting Instructions

D3C3n50r · 14 Oct 2015

Ah no worries i'll attach it again. Just fyi i'm posting all this stuff in Windows Safe Mode.

See you in another 18 hours T__T

Please disable driver verifier

Open an admin command prompt
Enter "verifier/reset" (without quotes)

The cause is the MagicISO SCSI Host Controller driver.
Likely you need to go to your manufacturer to update your drivers.

Code:

4: kd> lmvm mcdbus
start             end                 module name
fffff880`05619000 fffff880`05655880   mcdbus   T (no symbols)

Ok I ran Memtest again this time for 9 passes and still 0 errors (see below)

I've disabled driver verifier. Completely forgot I did this before while reading some other forum for advice (my bad)

I uninstalled "MagicISO SCSI Host Controller driver" as I don't really need it anyway.

Also according to "Driver Booster 3" all my drivers are fully updated.

The BSOD appeared again with the same:
IRQL_NOT_LESS_OR_EQUAL
ntoskrnl.exe / ntoskrnl.exe+735c0

I should also mention that I can not seem to open up Windows Update while in Safe Mode with Networking. Also if I were to do this in Normal mode it won't be long before a BSOD appears again interupting the update.

I've also attached the latest dump file as I guess you probably want this :)

Thanks again and awaiting further instructions.

Programs that claim to update your drivers install either the wrong or corrupted drivers.
If you have installed any driver with Driver Booster 3, please remove them as it may cause trouble.
