BSOD's, mostly during first boots of the day

[Dave76]

Default values, depends on the RAM SPD/XMP settings, you need to check that when installing RAM.

I'm seeing indications of the CPU overheating.
Use RealTemp and keep a watch on the CPU core temps.
Did you re-apply the CPU thermal paste?

You should remove your CPU cooler, clean with Isopropyl Alcohol, re-apply the thermal paste and install cooler.
Too much or too little thermal paste is bad.

Last crash:

STOP 0x000000F7: DRIVER_OVERRAN_STACK_BUFFER
Usual causes:  Device driver, Malware
Probably caused by : hardware ( nt!_report_gsfailure+25 )
DEFAULT_BUCKET_ID:  GS_FALSE_POSITIVE_MISSING_GSFRAME
SECURITY_COOKIE:  Expected 000035583368b3b0 found 0000008008b4da2b
IMAGE_NAME:  hardware
FAILURE_BUCKET_ID:  X64_IP_MISALIGNED

A driver has overrun a stack-based buffer.  This overrun could potentially
allow a malicious user to gain control of this machine.
DESCRIPTION
A driver overran a stack-based buffer (or local variable) in a way that would
have overwritten the function's return address and jumped back to an arbitrary
address when the function returned.  This is the classic "buffer overrun"
hacking attack and the system has been brought down to prevent a malicious user
from gaining complete control of it.

Let's make sure it's not a virus.
First d/l and run Windows Defender Offline.

Then Download and run Malwarebytes, be sure to update it before running.

If both of these come up clean then run Driver Verifier for 24 hours.
Driver Verifier - Enable and Disable
Post the full crash reports if you get any crashes.

Did you re-apply the CPU thermal paste?

Not yet. I'll look into it tommorrow though.

Both windows defender and malwarebytes did find 2 objects each and MSE did report finding something as well while i was running malwarebytes. Didn't seem like any serious threats but they are removed now in any case.

 

[Dave76]

What did they find?

Some viruses are very hard to get rid of, they just keep coming back if not removed correctly.

Run Windows Defender Offline and Malwarebytes again to confirm.

 

[Wyst3r]

The 2 items found by Malwarebytes are labeled "Spyware.OnlineGames". The files referred to were called "libmysql.dll" and "libsndfile-1.dll" located in C:\Program Files (x86). The only program that i have (accidently) installed directly in program files (x86) without it's own folder is a program called "Mumble" so the files might've been part of that, but i'm not sure.

MSE/Windows Defender only found some old adware in a video converter program called "OpenCandy". The object is labeled "Adware:Win32/OpenCandy" with a threat level of "low". It was located on a harddrive from my old computer.

 

[Dave76]

Only hits on Mumble said it was ok.

Have you had any more crashes?

 

[Wyst3r]

Nope, that last crash is the only one i've had for the past 6-7 days. So system seems fairly stable now.

Btw, I reapplied the thermal paste today and so far itseems like it might have given some minor improvements. One of the cores idles between 29-32 degrees while the rest are around 33-35 degrees. I think that's slightly lower than i had before but no major changes. It's been less than an hour since i applied it though and i've heard it might take up to 200 hours to reach full effect? (i used Arctic Silver 5)

Edit: Just got another crash, full report attached.

 

[Dave76]

Well, 6-7 days without a crash is good news.


Your last crash:

STOP 0x0000000A: IRQL_NOT_LESS_OR_EQUAL
Usual causes:  Kernel mode driver, System Service, BIOS, Windows, Virus scanner, Backup tool, compatibility, memory
Probably caused by : memory_corruption ( nt!MiDeletePfnList+1bd )
FAULTING_IP: nt!MiDeletePfnList+1bd
PROCESS_NAME:  chrome.exe
IMAGE_NAME:  memory_corruption
FAILURE_BUCKET_ID:  X64_0xA_nt!MiDeletePfnList+1bd

This crash indicates memory corruption, specifically PFN_LIST corruption. This can be caused by the RAM or a faulty driver.

Is your IMC and RAM voltages still at these settings?
VCCSA voltage, increase to 1.100v.
DRAM to 'Manual' and bump to 1.550v.

Run memtest86+ again, for 7 full passes.
Stop the test if you get any errors.
An occasional crash like this can be cause by an occasional RAM error, to find it you may need to run memtest86+ several times.

Another option.
You can increase the IMC voltage, VCCSA voltage to 1.150v.
Bump the DRAM voltage to 1.600v.
Test for stability, you can run the CPU:OCCT test for 30 minutes. Be sure to monitor CPU temps.

(The BSOD posting instructions said to reuse the same thread, so i'll do that even though this issue is unrelated to the previous issues.)

First of all, thanks for all the help i received the last time. Things have been running (relatively) smoothly since then.

So anyway, today while playing a game (as I normally do), I had a sudden BSOD. This was very unusual as i've never really had a non-startup BSOD in recent years. Anyway, after this event, Windows could no longer boot correctly. One of two things happen:

1. BSOD after the "Starting Windows" screen, where you'd normally expect the logon screen.
2. Black screen instead of the BSOD, it sits there for a few seconds and then computer beeps once, and a few seconds later beeps twice, then restarts.

I've tried all the steps i could think of (short of reinstalling Windows):
1. Startup repair / System restore - Restores are successful but don't solve the problem.
2. Last known good configuration - Doesn't solve the problem.
3. Safe mode + Networking - Works fine. Using it as i'm typing this.
4. Clean boot - Doesn't solve the problem.
5. Driver verifier - Instead of a BSOD/Black screen, the computer simply restarts after the "Starting Windows" screen.
6. Also tried disabling all services (including Microsoft), but still no luck.

Any ideas/suggestions on this would be greatly appreciated.

Edit: Ran ChkDsk, but it didn't find anything. Also tried a Windows recovery USB which said it found a boot error, and attempted to repair it. So now i have the "Windows 7 Ultimate (recovered)" option, which boots into a black screen (actually, there's no video signal at all) and the computer sounds like it's doing something but nothing happens and it stays there indefinately.

Alright, I think I've found the error, namely the graphics card. I installed a clean Windows 7 on a separate hard drive, and it worked well until i unstalled the NVIDIA drivers, after which i get the same BSOD errors as with the original installation. Considering the failure happend while playing a game, and the fact that safe mode works i guess it all makes sense. Also read that the error code i get (0x3B) could very well be video driver related.
