Hello,

I noticed that many people have found solutions to their problems in these forums. I hope I get mine fixed too.

Well I bought a new laptop Lenovo Z510 with 16GB of RAM already and it seems that I am dealing with tons of problems. I got it back to warranty they changed the RAM and the situation seems to have improved significantly.

But even with that I still have faced several BSODs and a lot of problems in the event viewer plus to random crashes for some some apps like firefox.

I attached the files hoping that we get this one sorted.

Hi seifsg and welcome to the forums ^_^,

First of all, thanks for your kind words, we try our best to help users solve their problems ^_^.

I have analyzed your Dump files and below has been provided an analysis for informative purposes :-

If we check the blamed modules, we get the Windows Components blamed. Now, since the chance of Windows components being at fault is extremely low, it means that something else drove it into fault. One of the components blamed is the NETIO.sys which handles the Network in Windows to be precise. This means that some application fiddling with the Network caused the bugcheck.
Below is a list of drivers which you must update.

Now, the drivers I have highlighted must be dealt with before we proceed further in case the problem still continues. The "ew_jubusenum.sys" belongs to the HUAWEI software which is pretty old according to the Dump File. Furthermore, there is presence of Bitdefender Antivirus which dates back to 2012 which is pretty old. According to me, both of them are conflicting with each other.

So, please update the Huawei software and remove the Bitdefender using this **TOOL**.

Just noticed your thread here as well so reposting my reply ^_^
 
re: Multiple BSODs in a new Lenovo Z510 Laptop - Windows 8.1 x64

Well that was a really great reply! Appreciated !

The thing is, I have two other laptops(not of the same model) , with the same windows version(windows 8.1 x64) and the same set of software installed such as the HUAWEI and the Bitdefender. They all work in harmony and peace. Could the software installed have problems because of this laptop specific model(drivers ) ?

And for the drivers, I installed all the available drivers from the manufacturer web site.

I bought it a week ago online from a well known webstore in the country, it came preinstalled, and with a lot of problems, so I had to send it back to them, then they claim to have changed the RAM and send it back to me, it come working but unstable showing these errors, should I send it back again to them or this is completely a software problem and not related to hardware.

-- I'm re-posting my reply here too :)

Thank you very much already, I really appreciate and high value the work you do .
 
re: Multiple BSODs in a new Lenovo Z510 Laptop - Windows 8.1 x64

On top of what blueelvis has said I would like to do somewhat of an analysis, I can't do much given it's a minidump.

Specifically the second dump file which is this:

Code:
BugCheck [COLOR=#ff0000]FC[/COLOR], {[COLOR=#0000ff]fffff90140a2a210[/COLOR], [COLOR=#ff0000]abc000015e081863[/COLOR], ffffd0002487aa30, 2}

This bugcheck indicates an attempted execute of non executable memory has occurred, this is not allowed as it says, this memory cannot be executed.

Looking at the Page table Entries of the address abc000015e081863 I see this:

Code:
3: kd> [COLOR=#008000]!pte abc000015e081863[/COLOR]                                           VA abc000015e081863

[COLOR=#ff0000]WARNING: noncanonical VA, accesses will fault ![/COLOR]

As far as I know this means that this address isn't allowed to be executed as it doesn't follow the normal rules of memory management.

Now this is where I have to attempt to make some educated guesses as memory management isn't my strong point although it is the most interesting, I do intend on learning more soon.
Anyway...

These are the CPU registers at the time of the bugcheck with the bugcheck stop error recorded in the rcx register.

Code:
3: kd> [COLOR=#008000]r[/COLOR]

I may be wrong but a memory write operation was meant to take place at ffffd000`2487a810 but instead wrote at fffff90140a2a210

fffff90140a2a210 Is the virtual address that contains non executable memory

The memory that should have been written to ffffd000`2487a810

Code:
3: kd> [COLOR=#008000]!pte ffffd000`2487a810[/COLOR]                                           VA ffffd0002487a810

Is a completely valid address.

Looking at your loaded modules I see you have Intel Rapid Storage Technology installed which is unnecessary and problematic.

Code:
[COLOR=#ff0000]dump_iaStorA[/COLOR]


Uninstall it from Control Panel > Programs and Features. Then Uninstall the driver from device manager.



  1. Right click on "my computer" icon and click "manage" on the context menu.
  2. It will open the "computer management" window.
  3. Select "Device Manager" in the left pane, It will list all the existing devices up.
  4. Expand "Disc Drives" by clicking on the triangle in front of it.
  5. Select one item under it, right click, uninstall.
  6. Continue the process for all items under "Disc Drives"
  7. Now restart the computer. At restart, windows will auto configure the appropriate system driver, msahci.sys.


 
Re: Multiple BSODs in a new Lenovo Z510 Laptop - Windows 8.1 x64

Bad news ... That did not work, I followed almost every step, I used some apps to check for my drivers, and I tried to remove unused ones, things got a little bit messy trying to install drivers that aren't provided by the manufacturer like Nvidia installing 3D Vision while my card doesn't support it, I even have problem with video games not playing sound.
New errors are appearing in the event viewer.Flash player and other apps are crashing randomly...
The weird thing that this more likely related to RAM, while the test is showing positive, could it be related to RAM voltage ?
Both RAMs are 1.5V and when I was researching in some forums, someone said that a Lenovo laptop with a Haswell CPU doesn't support 1.5V RAMs and it needs to be 1.35V RAMs.
Also when I sent it back to warranty I don't know if they have changed both RAMs or a single one, I guess that I bought a laptop with both RAMs not working, could that be a possibility ?
I am attaching a new dumb report file.

Re: Multiple BSODs in a new Lenovo Z510 Laptop - Windows 8.1 x64

Code:
BugCheck 139, {[COLOR=#ff0000]3[/COLOR], ffffd0002065b6d0, [COLOR=#008000]ffffd0002065b628[/COLOR], 0}

This bugcheck indicates a Kernel security check failed because it found a critical kernel structure had been corrupt.
More specifically a list entry data structure which is caused by drivers or malicious code, however given that it's a stack overflow (Linked list) and not a buffer overflow I have a strong feeling that you have a virus.

It may well be that a driver has called a function too many times which allocates a stack frame each time until it runs out of memory and a stack overflow is caused.

Enable Driver Verifier

What is Driver Verifier?


Driver Verifier is a driver monitoring program built into Windows from Windows 2000 and later.
Depending on the settings Driver Verifier stresses the driver selected and tries to force them to crash which causes a BSOD.


How to enable Driver Verifier:



  1. Go to Start
  2. Type in verifier.exe
  3. Click on Create customer settings (for code developers)
  4. Select Standard settings and IRP Logging
  5. Then hit next
  6. Click Select driver names from a list
  7. Select all drivers not created by Microsoft, Macrovision or Unknown
  8. Finally click finish then reboot your computer


What happens if it finds something?


When Driver Verifier finds a violation with a driver it bugchecks the system hopefully with the driver responsible identified.


How long should I run it for?


Normally around 24 hours, if it finds nothing by then chances are it's not a driver issue.


Do I need to do anything in particular when running Driver Verifier?


No, just do what you normally do when the system crashes to help maximize the chances of a crash.
 
Re: Multiple BSODs in a new Lenovo Z510 Laptop - Windows 8.1 x64

Hi,

I've been silently watching over and I thought I would mention that this looks like RAM to me. If Driver Verifier doesn't catch anything I would go ahead and run Memtest for no less than ~8 passes (several hours):

Memtest86+:

Download Memtest86+ here:

Memtest86+ - Advanced Memory Diagnostic Tool

Which should I download?

You can either download the pre-compiled ISO that you would burn to a CD and then boot from the CD, or you can download the auto-installer for the USB key. What this will do is format your USB drive, make it a bootable device, and then install the necessary files. Both do the same job, it's just up to you which you choose, or which you have available (whether it's CD or USB).

Do note that some older generation motherboards do not support USB-based booting, therefore your only option is CD (or Floppy if you really wanted to).

How Memtest works:

Memtest86 writes a series of test patterns to most memory addresses, reads back the data written, and compares it for errors.

The default pass does 9 different tests, varying in access patterns and test data. A tenth test, bit fade, is selectable from the menu. It writes all memory with zeroes, then sleeps for 90 minutes before checking to see if bits have changed (perhaps because of refresh problems). This is repeated with all ones for a total time of 3 hours per pass.

Many chipsets can report RAM speeds and timings via SPD (Serial Presence Detect) or EPP (Enhanced Performance Profiles), and some even support changing the expected memory speed. If the expected memory speed is overclocked, Memtest86 can test that memory performance is error-free with these faster settings.

Some hardware is able to report the "PAT status" (PAT: enabled or PAT: disabled). This is a reference to Intel Performance acceleration technology; there may be BIOS settings which affect this aspect of memory timing.

This information, if available to the program, can be displayed via a menu option.

Any other questions, they can most likely be answered by reading this great guide here:

Re: Multiple BSODs in a new Lenovo Z510 Laptop - Windows 8.1 x64

@Jared: No malware detected using the tool you provided. The system crashed twice after Driver Verifier have been enabled, I don't know how to identify if the crashes are because of the Verifier.I am attaching files here.View attachment SF_19-06-2014.zip.

@Patrick: I used memtest for about 8 hrs it only went through 2 pass's no probs detected but I have a strong feeling that the prob is related to RAM or other hardware problem because it is a new laptop and I am struggling to fix it in its very first week, I guess I'm going to send it to warranty, what do you think ?

Thank you guys for your participation, appreciated.
 
Re: Multiple BSODs in a new Lenovo Z510 Laptop - Windows 8.1 x64

I agree.

Since it is brand new, I would definitely send it in for replacement if that's something you're comfortable with doing. No laptop only a week old should crash like this.

Re: Multiple BSODs in a new Lenovo Z510 Laptop - Windows 8.1 x64

Hi,

Seems like you have advanced further on your way to troubleshoot the problem which is a really good thing ^_^.

I just would like to add a possible cause as well. In 2 out of 6 of your Minidump files, the driver at fault are related to your Networking in Windows and they are Windows components so there is a very rare chance to blame them. I can see the presence of 2 such drivers which are extremely old. Below is the list of those 2 drivers :-

1. HUAWEI Mobile Connect - Bus Enumerate Device (ew_jubusenum.sys) - Dating to year 2011

2. Intel Watchdog Timer (ICCWDT.sys) - Dating to year 2010

@Seniors :- Is it possible that this Intel Watchdog Timer is creating the rest of the BSOD's?

@OP :- Please remove the Huawei Mobile Connect driver and software. Furthermore, could you please verify if the issue still persists in the Safe Mode (It can be accessed by pressing F8 {Most Likely, even though other keys according to your Motherboard are also possible)?

I think that if the issue still persists in the Safe Mode, then as Patrick mentioned that it might be a RAM related problem, but if not then there could be some other fault as well.

Regards,
Pranav
 
Re: Multiple BSODs in a new Lenovo Z510 Laptop - Windows 8.1 x64

The Intel Watchdog Timer isn't necessary and it may well be the cause although I'm not entire sure why there is such driver.

Looking at the technical documentation for the driver is basically says what a watchdog timer is, it's basically a way of monitoring the operating system to see if it's functioning correctly.
It sets a timer for it count down, once it's counted down it calls the other elements and can then be reset by the reaction logic.
The timer is set on a specific task which is then monitored for completion, if it's not been completed within the time interval specific action is taken.

I've never used or looked into this software before but I wouldn't recommend it at all, I would remove it.

Sending it back is probably the best solution but that's your call, if you decide you want to do memtest and other means of debugging then we can but it's looking more like bad RAM as Patrick mentioned.
In fact, looking at the dump files I see that Driver Verifier is enabled but it hasn't caught anything and Page Frame Numbers have been corrupted, although this is usually driver related bad RAM ca also cause such issues, with all this said I think sending it back and getting a replacement/refund would be better.

You mentioned the RAM had already been changed but it could be either incompatible or the DIMM slots could be bad.

The memory being referenced wasn't even valid so a bugcheck would have occurred anyway, even if the IRQL wasn't 2.
