BSOD - Special pool detected memory corruption

Q: BSOD - Special pool detected memory corruption

Dear Tech Support,

I think my computer has serious problems. I don't know what is wrong with it because it is very fast and works very good. But something it just crashes out of the blue and gives me BSOD. Mostly the BSOD is Memory Management or IRQL not less or equal.

I have followed your BSOD Posting Instructions. The OS on this computer is Windows 7 (32 bit), before I had Windows Vista as standard OS on it. The computer is approximately 4 years old, with "Intel (R) Core? 2 Quad CPU Q6600 @ 2.40GHz 2.40 GHz" processor and 3 GB RAM Memory. I also have the output folder and perfmon file attachted to this thread.

Thanks in advance!

Preferred Solution: BSOD - Special pool detected memory corruption

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I don't see any crashdumps. You aren't using any "cleaning" software are you? The problem with them is they'll clean up crashdumps, which we need to analyze (plus most of them can end up being harmful).

Today I installed my new SSD, and installed windows 8.1.  It worked for the first 3 hours, until I got the special pool detected memory corruption BSOD.  I looked at other forums, and  I did the Memtest, and it didn't work.  It started happening when I got my ssd, anyone have any ideas how to fix this?
EDIT: I fixed the problem

I've been having lots of BSOD's and not been able to track down the issue.

Tried driver verifier and mem test on each ram stick but no issues.

Files attached. If anyone has any ideas I would be very grateful.

Hello, I have been trying for about a week now to fix the constant BSODs I have been getting with the error code with the most common error code of "Special Pool Detected Memory Corruption". A few details before the specs:
Never had BSODs before I recently upgraded the hardware on my computer
Had installed Win10 before I had upgraded any hardware without any issues
The only piece of hardware I did not upgrade was my PSU unless you count not upgrading my HDD
BSOD usually happen when I try to install something large like a game; rarely will happen randomly, but mostly will happen when installing something
Intel i7-7700K @ 4.2 GHz 
Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3000MHz C15

I'd suggest also checking over in the General Security forums for your status with the Spectre/Meltdown updates.
They can cause problems with booting and/or BSOD's - but I'm not familiar with the details on them.

Hi, trying to be quick before I BSOD again.

Recently had problems getting multiple BSODs, even though I haven't changed any hardware.

I got the aforementioned BSOD error and ran verifier to see the driver problem.

spqp.sys is the only one that came up that wasn't loaded it said "never loaded". I did a Windows Search for it and could not find it.

I don't know what to do know. Thanks in advance.

A:Special Pool detected memory corruption

Can you access the hard drive long enough to get a hold of the contents of the C:\Windows\Minidump folder? If so, zip it up and upload it to your next post.

What settings did you use when running Driver Verifier?

If the spqp.sys file was never loaded, then it's not likely to be a current problem. But a google for it doesn't reveal any results - which makes it suspicious IMO. Try posting over in the Malware forum for assistance: http://www.techsupportforum.com/f50/

W/7 SP1 64 bit 6GB RAM. I had a power outage and I'm now getting the above message BSOD. I have booted with a boot disc and ran chkdsk /R it found a few errors, I booted into Safe Mode once and that worked, but I decided to run Check Disk again, now it won't boot anymore. It won't boot into Safe Mode, stopping at C:\windows\system32\drivers\disk.sys. Check Disk starts at every bootup. From the boot disc in Command Prompt I ran FSUTIL Dirty Query, the results is Drive is not Dirty. I ran Memtest and the Windows Memory test, RAM tests Fine. I booted off W/7 DVD and try Startup Repair. It said this disc cannot repair volume. From the boot disc I tried to run Driver Verifier, it said it was not a Valid Windows 32 application. Not sure if this has anything to do with it, but I have 4 HDD's and when booting from the Windows 7 DVD or Boot disc, it lists the Windows Volume is Drive G: with Drive C: as the System Reserve. When the computer boots into Windows, the Windows Volume is C: I cannot boot into the computer to run diagnostic mode. I cannot scan for Malware, I cannot update drivers as I can't boot in. Not sure what else I can try before I re-install.

A:BSOD - Special pool memory corruption

This is (most likely) a malware issue or a corrupted driver IMO. This is also a Driver Verifier enabled minidump - please include information such as this in future posts. Please describe, in detail, what you've attempted to do to fix the issue - including links to any other online work.

Also, it's not usually sufficient to diagnose a Blue Screen issue from just one mini-dump - so please include all minidumps when posting here.

Please post over in the malware forums to ensure that your system is clean. The reason for this is the unidentified driver apx1gadg.SYS The forums are located here: http://www.techsupportforum.com/f50/

Once assured that you're clean, then try this:

Check to see if you have a program called Counter Spy installed. If so, uninstall it (making sure that you have other protection available if that's the only one you have on your system). The BSOD points to sbapifs.sys - a component of Counter Spy.

Finally, once you've accomplished all of this, ENSURE that you've turned Driver Verifier off. Leaving it on will make the system more unstable.

Here's the analysis:

These crashes were caused by memory corruption (probably a driver). Please run these two tests to verify your memory and find which driver is causing the problem.

If you are overclocking anything reset to default before running these tests.
In other words STOP!!!

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

RAM - Test with Memtest86+

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

Hello folk of Windows 7 Support Forums,
I've been having a lot of issues lately. It is a custom build, and I made it around June of last year. Recently, (in the past week) I have been getting a lot of blue screens. At first, I was getting Page Fault in Non Paged Area, since update drivers, trying memtest, and driver verifier, it is beginning to frequently blue screen with Special Pool Detected. I am using Blue Screen View. I have ran Check Disk with no errors. Whenever I play games (such as Chivalry, League of Legends, etc) they crash as well. I have updated my Nvidia Graphics driver from the site. Any help would be thoroughly appreciated. My dump info is attached.

Hey guys,

I just joined on here as I've gotten a little tired of searching for my specific issue. But basically very recently I started getting blue screened and I can speculate that it had something to do with the visual basic compiler executable. I don't personally use vbs, but I was using the Python IDE at the time if I remember correctly (it was a few weeks back now). So anyway, it's done it a few times since then, and it's happened twice today to the point where I can't get any work done. Apart from one out of the last 4, they've all been pool corruptions.

I will send you an example crash dump so you can tell me what you think. I'll oblige with any more information you might need, you need but only ask

NOTE: Please provide the following information for a more detailed response: http://www.techsupportforum.com/foru...ta-452654.html

While waiting for a reply:

I suggest starting all troubleshooting with the following diagnostic tests (located at this link: Hardware Diagnostics ). They'll save you a lot of time and heartache if there is a hardware failure, and you'll have the disks on hand in case you need them in the future:


H/W Diagnostics:
Please start by running these bootable hardware diagnostics:
Memory Diagnostics (read the details at the link)
Hard Drive Diagnostics (read the details at the link) - Test ALL of the hard drives.

Also, please run one of these free, independent online malware scans to ensure that your current protection hasn't been compromised: Free Online AntiMalware Resources (read the details at the link)

Hi all,

I have a long history of BSOD's with this computer during startup but I eventually discovered (also with the help of this forum) that they were caused by my DeathAdder mouse. BSOD's during startup have vanished.

Instead, they have been replaced with BSOD's during the use of Skype, Microsoft Word, LOTRO or anything else I might have running. There's no pattern that I can discern except the BSOD's originate under the Special Pool flag. I have previously turned on Driver Verifier to help get some additional detail in my dump files.

At this point, the best I can tell the BSODs point to my Webcam and NVIDIA drivers both of which are absolutely current and have been so for some time. I've reached the point where I need some assistance from someone with a lot more expertise in parsing out system info.

Thanks in advance for the help!

A:Memory Corruption?! [BSOD]

Hi jinxiang & Welcome to the forums ^_^,
I would need the Dump files in order to analyse the situation your system is in and help cure it ^_^.
Please note that without the Dump files, I can't help you out.
Kindly ZIP Up the dump files and then upload them to a File Hoster like Mediafire. The Dump files are located in "C:\Windows\Minidumps". You might need to copy them to some other folder before zipping them due to permission issues.
Once they are uploaded, paste back a link to it here and I would be glad to analyse them ^_^

Im constantly getting Memory Corruption BSOD within seconds or minutes of logging in to the computer. But the weird thing is after its crashed once it wont do crash again until a few hours later when you restart.

System Specs are in the tab at the bottom.

Ive replaced the graphics card with my old trusty 4870 ATI card and i still got these crashes. Ive even replaced the ram, i used to have 4GB of Corsair ram but changed to 8GB of G Skill 1600mhz ram.

The cpu is overlocked from 2.67ghz to 3.63ghz, all the overclocking was set up by a online company but after them failing to help me im willing to changed voltages etc, ill post details of the voltages later in case that might be the cause.

Ive replaced my keyboard/mouse/installed only basic software because memory corruption can range from any type of device/software/driver (googled it).
Ive also done a clean install of Windows 7 and removed and reseated most of the components.

Ive also attached the mini dumps in case anyone can make more sense from them than i can. Thanks.

Well these were casued by memory corruption. One ither thing I noticed was that your AVP.exe (kaspersky AV) was in the stack on several of the crashes. I would remove the AV and test the memory by downloading memtestx86 and run it for 5 passes.

system setup:

board: asus m5A99FX PRO R2.0 990FX

I have been having a bunch of crashes while playing games like Battlefield 3 and Wow. When I've played Skyrim and other games there have been zero crashes. Using WhoCrashed tell me about memory corruption, and doing Windows Memory check comes up with no problems detected. How should I go about figuring out what is the cause?

AX6950 1bg
AMD Phenom II x 4 965
G.Skil 6b (3x2bg) RAM

I think all drivers are up to date, but obviously one is causing a problem.

Any suggestions would be appreciated, I am pretty new to debugging so try not to use too much jargon.

We do need the actual DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

It is almost impossible to spot trends from a single DMP file so if you have more than one please upload them. If you only have one please wait until the computer crashes again then upload both.

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file at... Read more

Okay, so I just bought this really nice $4000 laptop and I've had it for 3 days now and you may be able to imagine my pained expression when I realized that I kept repeatedly getting blue screens... Sometimes it happens when I am playing facebook games, sometimes while watching youtube videos, and once while launching a game I play called League of Legends. I ran driver genius and it found 20 driver updates and I installed all of them so I am pretty sure all my drivers are up to date. I've tried reformatting, and I didn't get a BSOD almost all day, but then I finally got one again. I don't know if it is one of the drivers I have installed, or if it's my RAM, or if it is my SSD or HDD. I'm REALLY hoping this isn't a hardware problem because I don't have any blank discs at the moment to burn the memory tester for my RAM, I have 4 sticks of 4 gigs of RAM. If this does turn out to be a hardware problem I've already contacted the retailer of my laptop to begin the RMA process as a last resort. Any help with this would be sooo greatly appreciated. Before my reformat I had 5 other mini dumps and one of them was for pfn list corruption as well.

Hi everyone

I'm running a sony vaio notebook, vista home premium 32 bit, 3gb ram (2gb hynix, 1gb kingmax), intel core 2 duo t8100, ati mobility radeon x2300. I have been getting a persistent blue screen of death with the error message: "special pool detected memory corruption".

I have run the debug program and was hoping someone could kindly assist me with interpreting the minidump. The debug report says the problem is probably caused by "memory corruption". Please refer to the attached notepad file. Many thanks, from a relative computer newbie.

A:BSOD memory corruption, please help with interpreting minidump!

Hi -

The bugcheck on your attached dbug log -

0xc1 (0x90966fb0, 0x90966ffe, 0x33804e, 0x24), prob cause = memory corruption.

As you noted, 0xc1 = SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION = driver wrote to an invalid section of the special pool. The last perm 0x24 indicates that the driver freed memory in an improper manner.

Sorry, but not much can be done w/ that dump log. Run the driver verifier as it will help find the rogue driver:
START | type cmd.exe | right-click on cmd.exe uptop under programs | Run as Administrator | type verifier & hit enter - the Verifier screen will appear | do the following:


1. Select 2nd option - Create custom settings (for code developers)
2. Select 2nd option - Select individual settings from a full list.
3. Check the boxes? Special Pool
? Pool Tracking
? Force IRQL checking4. Select last option - Select driver names from a list
5. Click on the Provider heading - sorts list by Provider
6. Check ALL boxes where Microsoft is not the Provider
7. Click on Finish
8. Re-boot

If the Driver Verifier (DV) finds a violation, it will result in a BSOD. To see the status of Verifier - type verifier - select the last option on the first screen - "Display information about the currently verified drivers..". To turn Driver Verifier off - verifier /reset then re-boot. If you get a verifier-enabled BSOD, get it ASAP - go to \windows\minidump - get it, zip it up and attach.

Hello and thank you in advance for any help with this and all the great info in the forums that has helped me in the past.

Problem is, built a new system, mobo, ram, cru. power supply all new. Runs pretty good but highly unstable,
Anyway, the BSOD seems to happen mostly while doing updates to either windows or drivers. I suspect something to do with the ATI driver that came with mobo but i'm at a loss here as i got same bad pool header or memory management BSOD during fresh install.
Ran MemTest 11 passes 0 Errors.

Hi there,

My laptop has been crashing randomly for no apparent trigger. But a noticeable cycle is ~ every 12 days.

Every time is the same error: "faulty hardware corrupted page"

So I try using memtest86 but with no luck (10 passes all gd)

Then I use windows debugging tool to read memorydump. It said is a 'hardware error'

But I am not sure am I using the tool correctly, also there are too many stuff I have no idea....

So if anyone can help analyse the memory dump is greatly appreciated

Please see attachment for memory dump, it is create using the tool provided in post "BSOD - Posting Instructions"

Over the course of the last few months, I have been getting random BSOD's and crash's. I leave my PC on 24/7 and most of the time it runs great once it finally gets booted. A few times recently, I'll leave it at the desktop overnight and come back the next day to find a BSOD.

At some points it takes me 5-7 times of powering on and off to finally get it to boot into windows, otherwise it just BSOD's most of the time. Each BSOD shows a different code as well.

I tried memtest86+, i let it run for about 19 hours. It had either 13 or 18 complete pass's and 0 errors.

Im not sure if its a hardware failure, software clashing, or driver issues. Computer was customer built by myself about 5 years ago.

Any help would be great appreciated, as its really frustrating. At times I have to sit for about 20 minutes and hit the power button numerous times to get windows to finally boot. It's also been running much slower than usual.

I have ESET NOD32 AV if that makes a difference. No Wifi on this computer either.

Attached is the .zip of my dump files and other information. I hope I posted this correctly.

Hello all!

Built a system in January, solid as a rock ever since. Started ripping my dvd collection a week or two back, and started getting BSOD's after the third or fourth movie I ripped. Have posted my system stats elsewhere on the net and basically think that my ram is bad. Can this be confirmed? Also, assuming my BSOD's are ram related, is what I've attached to this post enough information to make a guess as to WHY my ram is going bad all of a sudden? The BSOD's only happen when ripping DVD using Handbrake.

Else where on the net, a forum reported to me that a memory leak can occurr between my Norton Security Suite and my Cisco VPN client. Can anyone confirm?

Edit: Running Win7 x64 on an AMD Phenom X4 965, 4 gb of Geil ddr3 (used to be 8), a Kingston SSD, HIS Radeon HD6850, and Jetway HZ03-GT-LF motherboard. Thanks.

Thanks so much,

Hey there, I'm having random BSoD's, anywhere from a couple hours to a day or so. Not exactly sure when they started happening, since the computer used to reboot itself (I changed that so I could see the stop error). Here's a small history of some problems I'd been having prior to the BSoD's:I had been using Nintendo's WiFi USB Connector (by Buffalo), and had many problems with it, mostly with not connecting to the internet (using the Nintendo Wii and DS), but my computer also randomly froze completely (no reset, no blue screen, nothing), with no indication of why. Usually it was just sitting on the desktop with nothing running but my Firewall and basic utilities (see under Software). This happened at random times, usually at night, and had happened while I was at the computer as well. I talked to Nintendo, and they told me not to use Spy-bot, Ad-aware, or AVG. I took them off (although I really didn't want to), and I still had the problems. So I am in the process of sending that back, and have completely uninstalled all of the software included with the USB WiFi connector. I had the exact same problem with a 3rd-party WiFi USB connector (WiFiMAX) before this. BTW the Nintendo tech Representative I spoke to was kind of a prick (you just don't whisper F**k! on a customer call!) and didn't seem to know what he was talking about (sounded like he was reading off of a screen).Here's the next piece of history:I upgraded the RAM from 256MB to 2GB (maximum allowed on ...

I have been getting some BSOD's for the past month or so. These are the three errors that I have received ... Memory Management, PFN_List_Corrupt and Bad Pool Header.

To try and solve the problem I have so far swapped the hard drive and reinstalled the OS (Win7 64). I also ran Memtest 86 on my ram. It ran all night and didn't find anything but I am thinking that perhaps I should test it one chip at a time. I have 3 4GB sticks of Tri channel memory so that is why I am thinking maybe they should be tested individually.

It is possible it is a driver but I have a pretty vanilla set up so I am a bit lost. I really hope it isn't a motherboard at this point. I am pretty tech savvy but I am struggling so I came here to beg for your wisdom.

I attached the dump file as directed.

I have been getting memory management BSODs left and right, but I have seen a kernal security check failure and a bad pool header. This has been happening since before I upgraded from 7 to 8, so I'm guessing it's hardware? In Win7 I started getting BSODs, mainly while playing games (since that is what I use it for mostly). Chrome also crashed a lot. I figured I put something on there I shouldn't have, so I decided to wipe it and start fresh with a my student copy of Win8.

With a clean slate (SSD and HDD formatted), the problem was still there. However, in Win8 I could see that it was a memory management error. I looked it up and learned about checking my RAM, so I ran Windows Memory Diagnostic, which didn't find any error, and memtest, which crashed every time. Tested my RAM in another system and it passed. Long story short: after RMAs and sending parts in, I'm sitting with a new motherboard and cpu, and the problem is still there.

Components and what (if anything) I've done to test them:

Old CPU: AMD FX-8150
Current CPU: AMD FX-8350
(brand new) With the new cpu but old motherboard, memtest still crashed.

Old Motherboard: Gigabyte GA-990XA-UD3
Current Motherboard: ASRock Fatali1ty 990FX Killer
(brand new) After swapping the motherboard, memtest now completes.

GPU: ASUS EAH6850 DC/2DIS/1GD5/V2 Radeon HD 6850
I don't know how to test this. I made sure the drivers were up to date.

So I think I've found the fault as when I try to boot Vista from both a CD/USB it blue screens and comes up with STOP 0x000000DE with the message "A driver corrupted pool memory used for holding pages destined for disk".

If I boot from the HDD it BSODs too and is a problem with "winload.exe", however I am pretty sure if I can get rid of this problem driver all will be okay.

However, as it won't boot I can't disable the problem driver nor system restore. I suspect the problem occured after Windows Update did an update.

Anyway, my problem is the above. So how can I disable drivers or system restore without using Windows' built-in functionality on a CD/USB? I assume there is other software I can burn to a CD/USB, I just don't know what!

Naturally, as this is likely a one-time use, free software would be preferable :)

Thanks in advance!

I recently have been having constant BSODs within the past month or so that at first seemed graphics related. I am not sure what the problem is but any assistance would be greatly appreciated.

OS: Windows 7 Ultimate x64 SP1
CPU: AMD Phenom II x4 965 Deneb @ 3.4 GHz
RAM: 8GB G.Skill Ripjaw Series DDR3 1600 (4x2GB) **Originally 4GB See Below
VID: Sapphire RADEON HD 6850 1GB
HDD: 300 GB Hitachi SATA (Primary) / 1.5 TB WD Sata (Secondary)
PSU: Thermaltake Toughpower 700W PSU

Originally I had thought this to be a graphics card issue because I had a prior GeForce GTX 280 die on me. It was replaced by a GeForce GTX 460 Superclocked and I was still experiencing BSODs.

After that I ran Memtest to test my ram and it came back with no errors. I only ran the test for a few hours so I am wondering if I did not test thoroughly. I ended up purchasing another 4GB and just replacing the original RAM. The machine still continued to blue screen so I figured it wasn't a memory problem and installed the original 4GB of RAM.

I am still continuing to receive 0x1A (Memory Management) and Bad Pool Header errors. Any help that I could get would be greatly appreciated.

A:Recent BSOD errors (Memory Management/Bad Pool Header)

Typical Memtest86+ runs should be done with at least 7 consecutive passes.

Nothing here is conclusive so far. I recommend you start Driver Verifier to see if it's driver related.

So far my biggest suspicion is hardware. One of the crashes mentioned code corruption where one solitary bit was lost. Often memory failure is not the cause of solitary bit problems, but they still have the potential to do so, in which case you'll want to run Memtest more. Usually, however, this is caused by either a failing Motherboard, CPU or PSU, or one of the components are overheating.

You can check with overheating using HWInfo with Sensors only enabled. Log two 30 minute sessions: one for idle, and one for high load (gaming, benchmarks, etc.). Send to use for viewing.

I built a computer last week and everything seemed to be going fine until earlier this week, when I had a BSOD while surfing the internet and running [email protected] on my CPU and GPU.

I didn't think much of it until I got another BSOD the next day, maybe while playing DiRT 3. The first two BSOD's gave me the Memory Management error, so I downloaded Memtest86+ and ran 7 passes with no errors.

I then got another BSOD while trying to play the Kerbal Space Program Demo and running [email protected] on both the CPU and GPU. This gave me the "Bad Pool Header" error. I tried several things after this BSOD, including flashing the motherboard BIOS to a newer version and uninstalling and reinstalling my video card drivers. I also ran a GPU memory stress test and a 15 minute Furmark stress test on the GPU, thinking it might be my problem. No issues.

I booted up the computer today thinking that my problems might be solved, and left the computer running all day with [email protected] on full on the CPU and GPU. I started the KSP Demo again and got the Page Fault BSOD within about 30 seconds of opening the game.

I'm at a loss as to what to do next. Thanks for taking the time to read through my issues and a big thanks for any help you can give.

Hi waharvey.

Before doing anything else, uninstall AVG following http://www.avg.com/us-en/utilities. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Download, install and update those, and then run full system scans with both of them, one by one; as the installed antivirus is failing.

Let us know the results. Will decide about the further steps after seeing it.

Hi all,

Thanks in advance for reading; any help is appreciated.

Experienced several BSODs during the past few weeks. A few separate "explanations" for the crash shown on the blue screens may suggest a memory problem:


A dump file created using the SF Diagnostic Tool is attached.

Some additional information:

The computer contains two sticks of RAM, each DDRIII 1333 4GB SODIMM. If it helps, the text on the label of each stick includes "BEFMHGO-[other characters]).

Memtest86 was run with both sticks in the PC (i.e., neither was removed before running), and a single error was found, with the following characteristics:

Tst: 1
Pass: 0
Failing address: 000bc646698 - 3014.2MB
Good: bc646698
Bad: bc01ff00
Err-Bits: 00659998
Count: 1
Chan: (blank)

System Restore was attempted, but could not restore the computer to a previous instance. Windows Defender Offline was also run and also failed, providing the following error: "The program's service has stopped. You can start the service manually or restart your computer, which will start the service. / Error code: 0x800106ba". Also ran BlueScreenView, which identified ntoskrnl.exe as a potential issue, although we weren't able to follow this up.

I hope that at least some of the above is relevant. Any help is sincerely appreciated.

Hi there,

I'm not sure where to begin with my troubles so I'm going to list all of them in chronological order:

1. I've been having a few BSODs the past two weeks, starting with page_fault_in_nonpaged_area. I left it alone.
2. I had installed a game that didn't work (graphics card on a laptop isn't so great) so I uninstalled it and downloaded new drivers for my graphics card. Installed those.
3. Got a virus on facebook where a person's account was hacked and they posted a link to a video where there was a virus. I got rid of the virus with AVG and by deleting all temporary internet files, cookies, everything and even scanning my computer with both AdAware and AVG in Safe Mode. So I should be clear of the virus except now my firefox doesn't work. Whenever I type anything in and push enter, nothing happens. I can browse though. I'm not sure if it's related to the Firefox profile I'm using right now, which was infected when with the facebook virus.
4. Decided to use System Restore to see if it would cause everything to go back to normal and went back to prior to the installation of the game (and getting the virus).
5. I'm now faced with two BSODs: Bad Pool Caller and Memory Management. I get them whenever I'm watching video (not youtube) on supernovatube. Obviously it's not a peripheral problem because I don't have any hooked on (except for a USB mouse). I ran Memtest86 last night and things came back clean.

I've attached the Attach.txt file and I can do a Hijackthis run i... Read more

Hello everyone,

Looking for some help on these issue. I just built a new system and have been having nothing but crashes. They don't happen when I'm doing anything in particular and sometimes happen right after I boot up. I have windows installed on a SSD drive.

I've tried reinstalling the OS, updated all drivers and BIOS, reseated memory and video card. I've also tried to install windows on a mechanical HDD as well. ntoskernel.exe seems to show up on all the crashes.

I've attached the file, please let me know if any other info is required.




Lets run a memory test

RAM - Test with Memtest86+

If you have more then 1 memory sticks if it fails test every memory stick on every slot .
