BSOD: ntoskrnl.exe+74ec0: error 0x000000c5 [DRIVER_CORRUPTED_EXPOOL]

ice70 · 14 Feb 2015

Hi,

sorry, not sure what I am doing to generate this error.

I have recently had problems where the network connection fails and I cannot connect to any sites.

I cannot bring up the task manager and when I try to restart the system just freezes. I can close my open programs and save.
This has happened maybe twice in the last week, but does not always result in the BSOD so may not be related at all!

I have attached the system info dump - but i removed hosts - i develop on this PC and I some of the sites are under non-disclosure agreements.
If hosts is really required, let me know and i will remove the sensitive sites and post up.

System install is reasonable fresh [replaced the C drive just before christmas] and the updates should be applied.

thank you for any help offered,
Ice70

Hello ice70, welcome to the Forums. I will see if I can help you.

First your 2 dump files:
Both blame the same thing

Code:

avgntflt
start             end                 module name
fffff880`09800000 fffff880`09824000   avgntflt T (no symbols)           
    Loaded symbol image file: avgntflt.sys
    Image path: avgntflt.sys
    Image name: avgntflt.sys
    Timestamp:        Fri Jul 11 10:46:47 2014 (53C006E7)
    CheckSum:         00026B8A
    ImageSize:        00024000
    Translations:     0000.04b0 0000.04e4 0409.04b0 0409.04e4

and

Code:

fffff880`11523878  fffff880`0a75f206Unable to load image avgntflt.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for avgntflt.sys
*** ERROR: Module load completed but symbols could not be loaded for avgntflt.sys
 avgntflt+0x5206

Both are your Avira Anti Virus. I would suggest uninstalling Avira and use the Avira removal tool Avira AntiVir Removal Tool - Download Replace it with Microsoft Security Essentials (Microsoft Security Essentials - Microsoft Windows).

I also noticed quite a few references to I/O procedures and NTFS file system, which I am sure you know is the file system Windows uses. Those usually indicate a hard drive or file system problem. You have a Samsung EVO SSD. Have you installed the Performance Restoration Software for it? They had a problem with them and released a firmware update that fixes it. It's about half way down the page Samsung SSD Downloads | Samsung SSD

I would also like you to run Seatools for DOS on your Mechanical Hard drives SeaTools for DOS and Windows - How to Use
also please run check disk Disk Check

One other thing I noticed is that you have 16 GB of Memory installed but only 8 GB usable. That is not really a big problem, but something is using a lot of memory. It isn't a problem but a concern.

Try that and see if there is any improvement and let me know.

ice70, after writing that message I was looking through some of your error reports and noticed several but the 2 most common were AI Charger Plus, which is part of AI Suite. AI Suite causes a lot of people great problems sometimes. I run it but have no problems.

The other is PSIA.EXE. It is usually a part of Secunia PSI Agent which verifies Software.

@essenbe
Hi! i am having a similar issue and was wondering if you could just take a look?
thank you!
If you could, here is the url for my post: BSOD during VLC
thank you!

rocco207, Your dump files are giving very little information. If you are overclocking anything, please set them back to default.

Please uninstall ALL Gigabyte Utilities you have installed. Next please reinstall the chipset drivers and the USB drivers. Disconnect all USB devices not needed for the computer to operate (keyboard and mouse).

Please run

ESET Online Virus scanner Scanner
Free Virus Scan | Online Virus Scanner from ESET
Download and install Free Malwarebytes and do not select the trial real time scan and do a full scan
Malwarebytes | Free Anti-Malware & Internet Security Software
Please download and install Free Superantispyware and do a complete scan
SUPERAntiSpyware | Remove Malware | Remove Spyware - AntiMalware, AntiSpyware, AntiAdware!

Also, I really dislike Norton. It causes all kinds of problems for people.

As with any 'free' programs, watch out for any add ons they want to install with it. Just uncheck them and they won't install.

With Malwarebytes and Superantispyware, do not use them as real time scanners, but use them as on demand scanners. Run them on a regular schedule, at least every 2 weeks. I use them and usually scan about twice a week.

After all of that, see if your results don't improve.

rocco207 · 14 Feb 2015

allright i will try all of this and come back to you!
thank you!

rocco207 · 14 Feb 2015

ok so i did all that you told me, and i am waiting for the bsod and dump report.
out of curiosity, what is what you asked me to do supposed to achieve?

Hi essenbe

first of all, thank you very much for taking the time to look at this for me.

Avira: I followed the link but I could not see anything other than the pdf? I uninstalled the software through windows installer, then ran CCCleaner on the registry. Not read good things on MS SE [too many things got through it], so installed avast instead.

Samsung EVO SSD - I have not installed the performance update for it. Started to, but backed away as there was a big warning about potential total data loss. It is my C drive and I have just installed it and would prefer not to do it again so soon

I looked around for the potential of data loss but could not see too much - it looks like it is a potential problem but relatively unlikely? I'll hold off that one for the moment until I have a work window that will allow me to re-install should the worst happen.

AT suite - I had not meant to install this.
It does state my motherboard: ASUS P8Z68-V Pro. There is an 'auto system level up' with fast & extreme, now I look at this, i think I may have clicked on fast! I had a freeze last night without BSOD and when I restarted I noticed something at the bottom of the 'american megatrands' page where my drives as devices are listed at startup - it said something about overclocking. I was not really paying attention and it has not shown again.
There did not seem to be a reset to default option in the auto system level up and was wondering if this may be part of the problem?

PSIA: I use this to keep my programs up to date - if it is causing a problem, do you have a recommendation for an alternative?

RAM: when I start up I have about 5 to 6 GB in use. Chrome uses about another 2 to 3 depending on how many tabs and plugins are running. Not sure what was running when I took the system info dump.

Will run Seatools for DOS and checkdisk and will report back on these once they are complete.

once again, thank you for your help,
ice70

On the firmware update, I used it and suffered no data loss. All firmware updates comes with that warning. It's just a CYA warning. Anything is possible, but also very unlikely.

I don't know what your problem is, but you should not be running with that much ram in use. I have 16 GB, and currently have 13.5 GB free.

If you have overclocked your system, that could very well be your problem. Especially if you did it with software. If you are going to overclock it, do it manually in bios. Then test for stability. I never recommend using software to overclock or to update drivers. I do it manually. Most software tells you if there is an updated version.

MSE is the only AV that has never caused a BSOD. The best AV is know what web sites you are going to, and what you download and where from.

Reduce the items that run at startup. Hold down the Windows key (the one with the flag on it) and press R. In the box type msconfig and press OK. In the window that opens click the startup tab and uncheck all the programs you have running at startup that are not needed. The only thing that needs to be there is your AV and Windows sidebar, If you use gadgets. Then press apply and restart. That does not mean you cannot use the programs you unchecked, it just means they do not automatically start when Windows does. The will run when you need them.

Hi essenbe,

thank you very much for taking the time to reply.

Running a checkdisk on all the drives. It will take a while so will let you know if there is anything to report. Still have the seagate dos hdd check to do, but will need to find a spare Flash drive or blank cd.

Uninstalled the ai suite and ran the Cleaner in safe mode. Also went through my start up and disabled things like the iTunes helpers And other thing that I do not use. Ram on start is now about 5gb. Things starting are the likes of apache, mysql, ruby and account sync tools, all of which are used both on a daily basis and from other devices within my local network. Chome is probably the worst ram hog (c. 2gb!), but it does what I need it to do.

Also reset my bios to defaults. Once windows started all attached drives and usb devices reinstalled their drivers. Not sure why but it seems to still be working, although there was an adrenaline spike on restart ;-)

Thank you for all your help,
Ice70
