The BSOD happens randomly. I have verified my memory using memtest and it reports it as O.K. along with all my other hardware. I'm a bit baffled by the whole issue and have spent hours searching for a solution to no avail.

You're help is greatly appreciated.

Preferred Solution: Random BSOD Windows 7 x64 --- Unable to verify timestamp for ntoskrnl

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

Related to NETIO.SYS. That usually means the malware app. You have two, which is never a good idea.

I would remove them both and replace with MSE.

Kaspersky is a frequent cause of BSOD's. I would remove and replace it with Microsoft Security Essentials AT LEAST TO TEST.

How To Find Drivers:

- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.

Hi All,

Been facing BSOD few times in a day.

Here's the scenario, previously everything was ok until remove my anti virus and some other files which i forgotten. and the BSOD appears, when i install a different AV, the problem still appears, when i view youtube video, BSOD again. when i watch video files, BSOD. when i run too many tasks - BSOD again.

mostly it says BAD POOL CALLER.

after all these BSOD, i tried update my graphic driver, and its still BSOD.

fed up, i formatted my drive and start everything from scratch.
so for fresh start in 5 days, i turn off windows update, never install AV and just run it by default and see how it goes. so far so good. no BSOD.

so next when i install AV, few days later it's BSOD again. so i removed it and do a Windows System Restore. so temporary no more AV. and i proceed to install
my canon printer driver and a software image viewer. it's BSOD again.

so i try downloading debugging software and open up the dump file and only says some error as shown below (i don't know what's that means)

unable to verify timestamp for ntkrnlpa.exe
also attached the dump file for you to review as instructed in forum.

Appreciate any of your kind advise.

My OS: Windows 7 ultimate x32 bit
Machine: Toshiba Portege T110 laptop.
Thank you!

A:BSOD - unable to verify timestamp for ntkrnlpa.exe or whatever


Update your Realtek wifi software\driver.

For AV,(remove any other av system security) download,install and use Microsoft security essentials with windows firewall.
Finish with these and post back.

A:Windows 7 random BSOD's ntoskrnl.exe


Here is your error and they are both read and write operations. You may follow suggestions in an attempt to alleviate the bsod.

Also, you can see if any patches are available for Call Of Duty 4.

Update your bios and chipset drivers if possible. Good luck with this.

"IMAGE_NAME: memory_corruption"

Run memtest for the system ram and find a software that can test video ram. Run these for as long as possible and that you can stand too. Sometimes, errors are only found this way.

Open an elevated command prompt and run this command as many times as necessary. One for each partition on the system, while changing C: to match.

chkdsk /r C:

If overclocking ram, video or memory, set to default speeds and test. If you are using performance memory, visit the maker's site for suggested Vdimm and timings to set in the bios.

Hi, I'm on a new build and have been getting random BSOD. I don't know exactly when it happens but it has happened a few times while browsing the internet on firefox.

I don't know what's causing these random BSOD. In BlueScreenView I can see about 6 crashes were caused by ntoskrnl.exe and one crash also had volmgrx.sys listed in it.

I attached the dump files so maybe you can help me figure this out. I'm using Windows 7 Ultimate 64 bit.

Thank you.

Been getting a lot of BSOD messages recently on my very new Windows 8.1 machine (both hardware and software), a lot of them are not creating dumps. Mainly related to ntoskrnl.exe but a number of crashes related to possible driver issues.

Have run/tried the following:
Malwarebytes - Not a single infection or issue.SFC - Scan is completely clean. Ran it probably at least 10 times.Memtest - Ran a full 12 hour scan. No errors.I've removed RAM, and tried difference slots, running on a single DIMM and multiple DIMMS in different slotsRemoved all external hardware. Only internal disks and Unifying USB for Keyboard/Mouse.Have run Driver Verifier, and this was consistently restarting my system, so it was showing something was wrong.Updated all my driversWindows Updates are current (and always are)Running latest BIOS

Today it happened when I was running Team Viewer. I don't know if that is what caused the issue, but generally I'm not running it when it happens. As you can see by the timing, it can happen overnight when I'm not doing anything at all. It's all very odd and driving me really mad, especially when I use this machine for a lot of work related activities.

Any help would be much appreciated.

Hey guys so I've been getting some random BSOD errors every few days or so. I usually leave my computer on when I am at work or sleep and either when I come home or wake up my computer is off. So I turn it on and it says that the computer didn't shut down properly when I start up. I downloaded the BlueScreenView and noticed I've had some BSOD three times within 10 days. One was a PAGE_FAULT_IN_NONPAGED_AREA error which I believe was a RAM problem (i bought new RAM and installed it plus OCed it to 2133, but I believe it was making my system unstable so I reset the speed to default and haven't gotten that error again), but after that I've gotten two IRQL_NOT_LESS_OR_EQUAL errors related to ntoskrnl.exe. I did some research online and from what I read it could be a number of problems. I'm just not sure where to start and could really use some guidance and advice. I uploaded my dmp files for anyone who knows how to look at these.

Thank in advance.

I'm getting random Blue Screens and can't figure out why. I'm not running any hardcore programs. I'm mostly just using Microsoft Office and Firefox. The BSOD's seem to happen when I'm in Outlook, Excel or Firefox. Haven't been able to determine exactly which at the time as I'm moving back and forth between them quite often.

I've tried the SFC command and it didn't find anything. I used BlueScreenViewer but not a lot of help. All drivers for sound and video have been updated. I've also updated the firmware to the Crucial M4 SSD version 040H.

Any insight would be great.

Been getting infrequent BSOD errors on my Windows 10 PC (Home edition).

I had a look on BlueScreenView, seems like a lot of the bugcheck BSOD is ntoskrnl related but I can't work out if it's hardware related or some bad driver somewhere.
The computer is 9 months old, custom built gaming PC.Temperatures are low <60C at load, <30C at idle (waterblock cooling on CPU)System is stable when gaming, a lot of the BSOD is happening at idle. (I leave my PC running all the time)The OS was upgraded from Windows 8.1 to Windows 10 in late 2015.System felt more stable under Windows 8.1, not really experienced many BSOD under Win8.1I have tested the memory with 10 successful passes (12 hrs).Have run DirectX diagnostics and cyclic Heaven/Valley benchmarks - no crash.

I'm having this BSOD since months ago and I can't find a good solution. Sometimes I can use my computer for over a month with no issues playing everyday for hours.. browsing the web etc. But sometimes like today I get 2 BSOD's on the same day playing for example Final Fantasy XIV ARR.

I tried many things before like Memtest, Cpu test, etc and I can't understand if my Hardware is the problem or some driver. I also have an after market Cpu Cooler so my temps are fine and my case has really good ventilation.

I uploaded this dumps a few days ago after I used Driver Veryfier. I got a C4 BC Code error on those Minidumps and the problem was nroskrnl.exe. Only with Driver Veryfier I'm able to reproduce this BSOD.. is always random when I'm just using my computer.

I have been experiencing quite a few BSOD's and freezes over the past week or so, at first I passed it off as a once off until it became more frequent (both BSOD and freezes)
I'm not sure if it would have anything to do with it but it started a few days after I started hosting a terraria server for myself and one friend; i recently (about 3 days ago) stopped hosting terraria, and began hosting starmade

just today I clean installed windows 7 and updated all of my drivers through "Computer>Manage>Device Manager" and still got another 6-7 BSOD's (some of which weren't in the minidump folder)
I might add that the blue screens tend to occur more while i am playing games (terraria/starmade) and the freezes occur during start-up, shortly after start-up, but rarely more than 10-15 mins after start-up.
my computer would also get into a routine where it would begin starting up (i would hear the fan turn on) but the screen would remain blank and it would automatically shut-down, and restart on its own. i would usually try to break this by turning off at the power point and waiting a short while, it would sometimes work, sometimes not

i don't know much at all, but by looking at the .dmp files most of them appear to be caused by ntoskrnl.exe

i have attached .dmp files from before and after the clean install

Hello I am new to posting here so apologies if I am duplicating any previous postings. I have spent 2 days trying to diagnose the problem with my HP Elitebook 9470m notebook PC running Windows 7 Pro with SP1.

Actions taken so far.

1. Have run memtest+86 and all came back fine. Have also run HP memory diagnostics in the BIOS and all tests were passed.

2. Have run sfc /scannow and also chkdsk and although some errors were found these were fixed.

3. Have run HP BIOS hard drive diagnostics test and HDD passed these tests.

4. Have run full Malwarebytes scan and all came back clear.

5. Have also run a proposed fix from tutorial found here NTFS.sys error 0x024- Tips and Tricks - www.retosphere.de& using Knoppix Linux distro to run ntfsfix command. The BSOD's are still occurring.

I can force the bsod to occur by attempting to launch Windows system restore. Whilst trying to open the program the bsod happens.

I can also force the bsod to occur by opening HP Support Assistant and attempting to update the drivers it informs me have an available update. The updates available are for an update to the BIOS and to the Synaptics Pointing Device.

I am uploading the results of my SF Diagnotics.

Thanks in advance


A:BSOD Windows 7 [[re: ...timestamp for ntkrnlpa.exe]]

Most likely the ntkrnlpa.exe error is due to improper symbols being loaded (or not loading at all) when running WinDbg. I didn't get that error when I ran your memory dump files.

That being said, there still isn't a whole bunch of useful information in the memory dump files.
FWIW - most times these sort of errors are due to malware - so I'd suggest running a couple of these free, online scans to rule that out: Malware

Also, please remove or update these older drivers that were loaded at the time of the crash. Don't use Windows Update or the Update drivers function of Device Manager.
Please use the following instructions to locate the most currently available drivers to replace the one's that you uninstall OR remove:

How To Find Drivers:
- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to

Hey guys, so I am in a bit of a pickle. I have an HP m6-k015dx laptop and it is giving me hell. I will get random BSOD's, usually at or a short while after login. They usually happen consecutively and then stop. I was able to enable driver verifier in order to see what was wrong. After it was enabled it did not crash so I decided to use memtest to check the RAM. 50% into the first pass it had detected 650 errors. So I tested each stick in each slot and it came back fine. I then tested both sticks again and it came back without an error. I tried to boot normally but I received multiple BSOD's. I then booted into safe mode with networking and received a BSOD. After that I booted into safe mode and was able to retrieve my minidump files. After analyzing them on another computer each one says that it is probably caused by ntoskrnl.exe What is my course of action from here on out? I really have no idea what to do.

My mindump files are zipped and attached.

i just buy a decent gaming pc with the prices about 600 $

processor : fx-6300 six core
graphics card : gtx geforce 650 ti
ram : 8 gb
anti virus : eset nod antivirus 32

i buy the pc without hardisk,since i want to use my old hardisk.
since the first day i buy the game a bsod apeared,but cuz i have little time
i never go to the shop again.until i think after about 5 month the pc can't
boot and always stuck on the startup with black screen and no cursor.
before that happend the pc always got bsod or sometime just a blank screen with random color,the bsod is always random,sometimes it say bad_pool_header or irql_not_less_or_equal or something like that.so i bring the pc to the shop,it say that my hardisk and graphic cards is broken,so i change the gpu to nvidia geforce gt 740 and buy a new hardisk.

and so i re install windows and buy a new casing,the bsod appear again with bad_pool_header.i was desparate since am not computer expert so i don't know what else to do and the shop where i buy is just a dead end since they don't really know what's wrong.so i browse the internet,run memtest,downloading the blue screen viewer,and i suprise that i got so many bsod with the same driver error,ntoskrnl.exe . so i browse the internet searching how to fix ntoskrnl.exe bsod. but i don't have time to do all of the method.

Dear Sir

I had some BSOD, since several months... It mostly occurs during a games and watching videos on Youtube, also in VLC and other video players. It always look the same: screen freezing-->sound looping-->reboot.

You are my last hope ...

I guess you have tried various versions of the display driver and now using the latest BETA, but still it is the same? Your earlier BSODs were stop 0x124, but the latest one is stop 0x116, which will provide us a more room to troubleshoot.

My PC is 1 year old and since I've got it produced a lot of BSODs. It seems a random event, i got BSOD when play games, surf internet, watch movie, do file operations, and also when pc was idle. I tryed more Windows 7 versions legal and integreted warez version too. I tryed latest stable and beta drivers too.
When Ive got the pc I ran memtest86 in all slot 8 passes, and then all dimm in one slot too, so i think its not a memory problem.
I didnt overlock any hardwares.
My PC:
cpu: i3-2120
mboard: ASRock B75 Pro3
memory: 2x4GB Patriot 1333 dual channel (PSD34G13332)
gpu: Sapphire hd 7770 vapor-x
ssd: Samsung 830 Series (64GB SATA3 MZ-7PC064B/WW)
hdd: Maxtor 300GB (6L300S0)
Seagate 2000GB (ST2000DM001)
psu: Thermaltake TR2 RX W0146RE 450W

The system is on the SSD. I suspect the Seagate HDD because i had to do sometimes chkdsk, sometimes it has found faults sometimes not.

I want to change to win8.1 but before I buy it I want to know what cause the BSODs.

I have about 50 minidumps, maybe you can find something important in them.

(Sorry for my weak english, not my mother language.)

Welcome to the forum.

There are no outdated drivers which means it might be a hardware problem.

Hello, I'm new to the this community. I've come because I'm having random bsod's I've tried even reformatting to no avail.

I'm running Win 7 Ultimate 32bit Retail.

I've ran the system repair on the win 7 disk but it hasn't helped.

I've attached four minidumps(I've renamed the .txt because it wouldn't let me upload .dmp's). I'll be very happy if someone can give me a clue to what's going on.

It seems to be ntoskrnl.exe. Which I've heard might have to do with the keyboard so I swapped it, but it didn't help.

I've ran WhosCrashing and I have this info:

A:Random bsod? ntoskrnl.exe

If you upload dump files, please zip them up. They take less space and are easy for us to handle.

Unfortunately, the Windows Debugging Tools aren't able to access symbols for your operating system files (in particular NTOSKRNL.EXE / NTKRNLMP.EXE / NTKRNLPA.EXE / NTKRPAMP.EXE) from the Microsoft Symbol Server - so that makes debugging them difficult if not impossible.

Please do the following (this will not affect the analysis of the current files - but it may help later files that are acquired):
- activate/validate the Windows installation at Genuine Microsoft Software
- run sfc.exe /scannow to replace any problem files
- open a support incident with Microsoft to see if they can fix the missing symbols issue ( Windows 7 Solution Center )
- If that doesn't fix it, then wipe the hard drive and reinstall Windows
- don't use "leaked"/torrent builds

please remove or update these older drivers that were loaded at the time of the crash. Don't use Windows Update or the Update drivers function of Device Manager.
Please use the following instructions to locate the most currently available drivers to replace the one's that you uninstall OR remove:

How To Find Drivers:
- I have listed links to most of the drivers in the code box below. Please use the links there to see what info I've found about those drivers.

I have been getting BSODs randomly ever since I built this PC. I have looked online and checked the dump files and all appear to have something to do with the ntoskrnl.exe file. It looks as though it could be a number of different issues from drivers to RAM to my HDD.

Does anyone know what it could be specifically? I have attached the SF Diagnostic Tool's output zip with all the info.

Thanks in advance,

Welcome to SevenForums,

F4 is usually related to storage/hard drive.

Do you have a SSD? Did you update to its latest firmware for it?

Start by testing the hard drive:

Upload a screenshot of your hard disk using crystal disk info:CrystalDiskInfo - Software - Crystal Dew World
Screenshots and Files - Upload and Post in Seven Forums
Run Disk Check on your hard disk for file system errors and bad sectors on it:Disk Check
Hard drive test both short and long with: SeaTools for Windows

Hey guys, first time posting here
So a couple of days ago I downloaded a file which was an installer for a game which my Antivirus (Avast) deemed safe but after installing the game, I started experiencing slow performance and unable to use any web browsers and occassionally experiened BSOD. I thought that a virus or malware infected my computer so I scanned my computer for viruses with AVAST and malware with Malware Bytes. After removing all infected files, the web browsers started to work and computer performance improved but not fully, although I thought scanning my computer should've help fixed the occuring BSOD, it still continued to happen but it happens randomly instead of occassionally. I even tried using chkdsk but it will give me the same BSOD screen at around 10% therefore does not give it a chance to finish scanning. Every BSOD I manage to catch a glimpse of the executable file that was specified which was ntoskrnl.exe. I tried looking around for solutions but so far no good although the BSOD is happening more rarely but nonetheless still occurs. Therefore I was wondering if anyone could decode what could the problem be?

Hi wraggzeh, the first step would be to get a legitimate copy of Windows preferably Vista
as that PC doesn't officially have drivers newer then 2009 (except for one which is dated 2010)
and the fact that it come preinstalled with it, that shouldn't be a problem if you hopefully didn't
wipe your restore partition. Also make it x86 (32bit) as oppose to the x64bit you have installed at the moment
seeing you only have 1GB of RAM.

As for a bit of hope, the Bugchecks are all the same.

Hi guys,
I've been getting several bsod crashes in the past months. Sometimes they happen up to two or three times in a row, or in the same day. Sometimes they just stop appearing for a week or so, just to comeback again.

I tried a couple of times to format through the Recovery app that came with my pc, but the problem persists. Even get a bsod the first time I booted up a fresh install of the OS.

So I dont know what to do anymore. I ran some tests for both, hdd and memory, but the results came clean.

I checked the dumps with BlueScreenView and it appears most of the crashes are caused by the ntoskrnl.exe driver.

I really hope you can help me,
if you need any more info please let me know .
thanks in advance.

I revamped an old X58 build some months ago. It was an inherited computer with several problems. I have been changing most of it (CPU, MOBO, RAM, HDD) but random BSODs keep happening.

I'm running a fresh install of Windows 10 Home x64, installed on a new SSD. This is the 3rd time I have to restore Windows this week cause it keeps corrupting itself given a time. I tried default drivers, old drivers, new drivers, but nothing works, and eventually I get BSODs related to IRQ/Memory/DRIVER_IRQL_NOT_LESS_OR_EQUAL/DPC_WATCHDOG_VIOLATION/Threads bad handled, etc. I have it slighty oced, and heavily tested with Linx/Prime/Memtest/Cinebench/etc for stability.

BSViewer mostly blames ntoskrnl.exe, but I can't dive into the minidump. I will attach last one.

I'm really desperate. I have an even older setup with mostly same onboard devices on a X48 platform running flawless.

Any help would be very much appreciated.

Probably caused by : memory_corruption ( nt!MiGetNextNode+15 )

Usual causes: Insufficient disk space, Device driver, Video card, BIOS, Breakpoint with no debugger attached, Hardware incompatibility, Faulty system service, Memory, 3rd party remote control
memory_corruption doesn't necessary mean that a RAM module is faulty, it can also point to a object which corrupted the RAM at the time of the crash, for instance a corrupted driver or program. Paging files and the CPU caches can also be causes.

Follow these steps -

Test for any corrupted drivers, by running Driver Verifier for least 24 hours, stop the test if a BSOD occurs before this time frame. Driver Verifier will place stress on the drivers within your system, which will cause corrupted drivers to crash and hopefully be pinpointed.Driver Verifier - Enable and Disable
Memory:RAM - Test with Memtest86+
Run Memtest86+ for least 7-8 passes, and preferrly overnight as it can take a while to fully complete.

Test each RAM stick individually, if an error is found then move the same RAM stick into the next DIMM slot and test again, if errors are found for the same RAM stick in every available slot then you have a faulty RAM module. On the other hand, if no errors are found in the next slot or the other slots for the same RAM module, then you have a faulty DIMM slot.

Quick history of my PC. Bought it pre-made back in 2010, with the last 2 years i have upgraded to a SSD and a new graphics card. Within the last 2 months or so I started getting intermittent BSOD's. I decided(probably stupidly) to upgrade to Windows 10 from 7, I figured I didn't have much to lose and it may help. It appeared to help, for a while and now I get BSOD's more then ever, at least once a day. There doesn't seem to be a pattern to it, my PC may be idle while watching TV and I hear it reboot.
I attempted to run memtest86+, but I couldn't get it to boot. I was able to do it on another PC, but not the one in question.
I instead tried just running the windows memory diagnostic and it came up with nothing.

On a side note, I'm considering just scrapping the PC, and taking the GFX card and SSD and putting it into a new build if this one doesn't have an easy fix.
Thanks for any help. I've been on forums, google nonstop the last couple of days trying to get a fix but no luck, so any guidance is greatly appreciated.

But now in my computer info it is telling my 6 GB, I opened the PC up and saw 4 sticks (I'm assuming 2 GB a piece). Is this some kind of trickeration(like it only shows what is usable or something) or could one of the sticks or the mobo port be bad?

I am getting a BSOD randomly whether in Safe Mode or not.  I have tried reloading Windows several times, but I don't have an original Windows 7 disk.  I have run memory diags and all came back fine.
Here is my configuration:

A:Random BSOD - ntoskrnl.exe

Bugcheck 109 means kernel code some how became corrupted and the kernel patch protection called the bugcheck function to prevent compromising security. There is usually caused by either one of the below reasons.
A hardware corruption occurred, e.g. failing RAM holding kernel code or data.
 A driver has inadvertently or deliberately modified critical kernel code or data. Most probably malware infection.
​Please try the below steps.
 Run Memtest86+.
Since the BSOD also happened in safe mode, we should begin with a hardware verification. Most reliable tool to perform a memory test is Memetest86+. What you need to do is run at least eight passes with this tool. Read the below guide for detailed instructions.
Make sure to complete at least eight passes. Otherwise it may not catch errors.
Scan for malwares.
 If the memory test came clean,run a malware scan using the below tools preferably from "safe mode with networking".
Malwarebytes free (run a full scan) : http://www.bleepingcomputer.com/download/malwarebytes-anti-malware/
ESET online scanner : http://forums.majorgeeks.com/showthread.php?t=149856
If there are infections in your machine, you can request help from a trained malware removal expert to properly remove them.

Hello, I'm relatively knew to this forum so I dont know what to really post except for the .dmp files and what "bluescreenview" says. here goes.
Attached are .dmp files.
According to bluescreenview, all of my BSODs (which is over 30) have involved ntoskrnl.exe with the bug check string on most of them being "APC_INDEX_MISMATCH".
There are some misc. files being the causes of my BSOD's such as hal.dll with the bug check string as "DRIVER_POWER_STATE_FAILURE" which happened 2 hours ago.

This is the log from the last BSOD

Please advise me on what to do. I'm tired of these BSOD's that happen so randomly.

Okay, so I have a custom built PC (Specs in my profile). Well, I used to game on it regularly last summer before heading to school, and I never got any BSOD's or errors or anything really. Well when I got back this summer, I started getting gamename.exe has stopped working for all games I had when I attempted to play them, and then I started getting the BSOD's.

At first it seemed like it was just from gaming but then they started happening just randomly. While downloading, watching videos, etc. Just basic stuff.

I researched about as much as I could, tried memtest, no errors. Tried using seatools, no issues that it found with the HDD. Now I have completely formatted my HDD and reinstalled windows, but to no avail. I'm sure there's a lot of out of date drivers, considering I recently formatted (like yesterday). Hell, I'm pretty sure I have the oldest version of Win 7.

I included a couple screencaps from BlueScreenView in my zip file. The one titled "abnormal," I've only seen once. The other one I've seen about 10-15 times.

If anybody could point me in the right direction, I'd be extremely grateful. Just FYI, my MOBO is brand new, as is the RAM, and I just bought a 650w PSU, so I wouldn't expect it to be a hardware issue. I've spent about $900-$1000 on this computer, and I really need to figure out how to get it running right again. Thanks for any and all help.

Which antivirus do you use?

Scan the system for possible virus infection with the following programs only.
Anti-rootkit utility TDSSKiller
Windows Defender Offline
Do some Disc checks.
Re-seat the sata and power.

Run chkdsk /f/r, following the option two of the tutorial Disk Check
Seatool for dos: SeaTools | Seagate download
Burn it in a blank cd. boot from the CD, click on "Accept", wait for it to finish detecting the drives, then in the upper left corner select "Basic Tests", then select "Long Test" and let it run.
Post a screenshot of your HDD using CrystalDiskInfo - Software - Crystal Dew World.
Download and install CCleaner. Then run it.
Go to "Tools" .... by default it will open the "uninstall" tab.
Click on save as text file. Save it on your desktop.
Upload the text file for us.

Let us know the results.

Computer crashes sporadically with no apparent trigger. Can happen while gaming, browsing, idling, or posting threads.
Already gone back to microcenter 2 times and replaced motherboard, memory, and diskdrive. I really hope its not hardware related again....
BlueScreenView primarily blames ntoskrnl.exe, but usbccgp.sys, Videoprt.sys, and some direct x crap has recently joined the bsod club.
I have reinstalled the OS 3 times on different drives each time, but still the same problems. I have done virus scans, registry cleaning, defragement, sfc, memtest for about 12 hours no errors, driver updates, and offered incense to the microsoft gods.
please help me! lol.

Counterfeit installations such as yours (Lenova2 OEM on a retail motherboard) contain heavily modified code that causes the installation to behave it unexpected ways, hence your multitude of errors. Analysing BSOD's and determining their causes on these sorts of installations is very unreliable. For this reason, many analysts won't attempt it.

My recommendation is to stop spending money on replacing the hardware, and use it to purchase and install a genuine Windows 7. This will minimise the problems you are experiencing, and make subsequent diagnosis of BSOD's far more reliable. Once you are running a genuine Windows 7 installation, and are still experiencing BSOD's, we will be happy to help you solve them

I am trying to resolve BSOD's on a Lenovo T420s and I have tried the following:
Chkdsk, Bios update, virus scan, memory scan - pass, hard disk test - pass, but at any moment the system crashes. I wish i knew how to read minidump files to really know what the cause is to fix. if anyone can help me out in anyway is much appreciated. Also attaching Bluescreenview log file as it is too much to fit in this thread.
