Previous thread I joined in on with all of the problem description/data/tests information in there.

 

Short version -

 

Windows 10 crashing, boot loop.  Must disable driver signature enforcement in order to boot.

SFC finds files that are corrupt but cannot repair then.

Image checker/restore does not fix.

Malwarebytes finds nothing.

adwcleaner found items and upon removing, problem does not change.  Re-scan finds nothing.

Memtest86 finds errors in a range of memory from ~500-1200 I think.  Tried swapping ram sticks around the slots (4 slots, 2gb each), problem got worse.

Blue screen view shows all crashed from ntoskrnl.exe and the bug check is 0xc000021a.

Sigcheck finds multiple drivers unsigned.  I have updated everything that I was able to find through a driver updater, still no change.

I have also tried to do a reset with and without keeping personal files, the reset fails every time.

 

At this point I'm not sure if I have some kind of hardware failure in the works or if the software is the problem.  When the first crash occurred I was exiting Diablo 3 and BSOD.  It did not occur while playing.

 

Was told by Usasma to start my own topic.

I'm running late for my first day back at work.

The first thing is to fix the RAM problem. 

If any of the RAM sticks are bad, they MUST be removed.

 

Try the sticks one at a time in the first slot

Let the test run for 3 passes (or until you see errors) - this will help see which sticks are good and which are bad

- If all fail, then try in the next slot, etc, etc, etc (this will help see if it's sticks or slots that are bad)

If some pass, take one that passed and try it in each slot (this will help see if any of the slots are bad)

Let the test run for 3 passes (or until you see errors)

 

Once the hardware problems with the sticks is fixed, then we can move on to seeing about the software. issues (and the system should run better with good RAM)

There are 4 slots on my MB.  I am not sure which is the first slot.  I have tried swapping the two outside ones and even removing one of them and am not sure.  Could not find a diagram of my MB either.  Asus CG1330-5

By convention, the first slot is the one nearest to the CPU

But it really doesn't matter as you can just pick one as the first and test from there.

 

Take ALL of the sticks out using proper anti-static precautions ( https://www.google.com/search?q=antistatic+precautions&ie=utf-8&oe=utf-8 )

Test the first stick (just pick one - but keep track of which you've tested and which you haven't) in the first slot (again, just pick one - but keep track)

Run MemTest for 3 passes.

 

If it starts to spit errors, stop the test and put the stick in a place that you've decided to put the bad sticks (you don't need to run 3 passes if has errors - they aren't going to get any better)

If it doesn't spit errors by the end of 3 passes, then stop the test and put the stick in a place that you've decided to put the good sticks.

Repeat this with the other sticks until you've tested ALL of the sticks in the slot that you chose for the first slot.

 

Then, take one of the good sticks, and test it in each of the other slots.

Run MemTest for 3 passes

 

If it starts to spit errors, stop the test and remember which slots have passed and which have failed

If it doesn't stpit errors by the end of 3 passes, then stop the test and remember which slots have passed and which have failed

 

At the end of testing, please let us know the results.

 

FWIW - if ALL the sticks fail in the first slot that you chose, then start over with the second slot (testing ALL of the sticks in the second slot).

Do this until you find a stick/sticks that pass - then resume the testing of the individual slots with a good stick.

Continue until you've tested all of the slots

I noticed on my board I have 2 blue Dimms and 2 black. They are also named A2 B2 A1 and B1 as you move away from the CPU. Do you know how they are ordered?

Took a guess and eliminated the bad stick on first try.  Pulled it out of A1 and ran test, no errors.  Took stick from another slot and put in A1 to confirm whether or not slot is bad, ran test again with no errors.

In order to figure out the difference between the blue and the black slots, you'll need to provide the model # of your motherboard.

 

Don't forget that you have to test ALL of the sticks.  There may be more than one bad one.

They have all been tested. The three remaining sticks are good. I am ready for the next steps.

Does the system still crash in a boot loop?
Do you have to disable driver signature verification in order to boot to Windows?

 

If that's the case, then make the system crash 3 times, then recover and let's have a look at these reports:

 

Report Set #1)  Please run this report collecting tool (even though you may not be experiencing BSOD's) so that we can provide a complete analysis: (from the pinned topic at the top of the forum)   http://www.bleepingcomputer.com/forums/t/576314/blue-screen-of-death-bsod-posting-instructions-windows-10-81-8-7-vista/
FYI - I don't often use the Perfmon report, so if it doesn't work please just let me know.

If you have problems with it running it, there's an alternate tool here (direct download link):  https://github.com/blueelvis/BSOD-Inspector/releases/download/1.0.5/BSODInspector-1.0.5.exe

NOTE:
Please zip up the (.ZIP) files - do not use .RAR or other compression utilities. 
.ZIP is the type file that can be uploaded to the forums.

Report Set #2)  Please do the following:
- open Event Viewer (run eventvwr.msc from the "Run" dialog)
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on the "Administrative Events" heading
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here:  http://support.microsoft.com/kb/2028504

While waiting for a reply, please monitor your temps with this free utility: 

 

SpeedFan v. 4.5.1 and later (free from here:  http://www.almico.com/sfdownload.php ) can log temperatures in a CSV file:
You may not need to log temps - if uncertain, please ask.

To make it work (log the temps to a file) you have to do BOTH of the below:

1. Enable logging in general: Configure...Log...check "Enabled" then click on OK to save.

2. Enable logging for specific checks: Configure...Temperatures..left click on each sensor, then click on "Logged" at the bottom of the Window (for our purposes we want them all) then once you've selected "Logged" for all sensors, then click on OK to save.

The log will be located at C:\Program Files (x86)\SpeedFan[quote]Naming: log files are named SFLogYYYYMMDD.csv, where YYYY is the year (four digits), MM is the month (2 digits, zero padded) and DD is the day (2 digits, zero padded). If a file already exists by that name, the file that already exists is renamed according to the following naming scheme: SFLogYYYYMMDD-CCCC.csv, where CCCC is a increasing number. The new file is then created with the standard file name scheme.

Notes: whenever you change the options related with logging, SpeedFan starts a new log file.
NOTE:You may want to turn logging off when we're done - as I don't know it's impact on performance or on the system.

 

While waiting for a reply, please also start on these free hardware diagnostics:  http://www.carrona.org/hwdiag.html

Please finish ALL of the tests and then let us know the results.
