Windows 7: Random freezes and/or BSOD with general use

Random freezes and/or BSOD with general use

Hello all,

It's been a while since I've posted here but just recently my Alienware m14x R2 has started randomly locking up completely to the point where I have to do a hard shut down. This happens at sporadic times - sometimes it will just power up and it will happen 2 minutes in to use and other times it might happen 40 minutes later. When using the laptop in safe mode it never happens which leads me to believe it is software related - fingers crossed though as a new mobo on these puppies is like upwards of +$500.

I have already performed a few different restores and even used AlienRespawn to bring me back to factory stock but the issue still persists which makes my software issue theory a little less likely.

I know I have to follow the BSOD crash instructions for this but those don't occur hardly as often as the random lock ups - also BSOD are hard to replicate as I have no idea what sets it off.

Any help or suggestions would be great.

If you already have had BSODs, then you must already have some dumps. Check the Minidump folder under your Windows folder. If you don't have your BSOD settings to create a Minidump, then open Computer, right click and select properties. From there, click on Advanced system settings and under the Starup and Recovery section, click on settings. Under the writing debugging information section, select Small memory dump (256 KB) and click OK. Also, if you have another computer and a USB drive, download the SF Diagnostic Tool from this link SF Diagnostic Tool - Using for Troubleshooting and put it on the USB. Start the problem computer in Safe mode and insert the USB in the problem computer and right click the application and click Run as Administrator and follow the steps given in the link. Get the files generated by the tool on the USB and upload it here with the other computer. This will give you a bit time before your computer freezes again. Some BSODs are software related but it is hard to know if it really is or not without having the dumps.

Okay I do have a dmp file from a blue screen that just occurred a few minutes ago but it was when Kernel memory dump was selected - I just now changed it to Small memory dump (256 KB). I can provide you with that if that helps. I do have two other PCs will download SF Diagnostics tool now, run that and provide you with the files.

P.S. I am currently on my laptop and all is well but this is normal as it locks up or BSOD at very random times.

EDIT: I ran SF Diagnostic tool and it did not create a folder on my desktop. I know it says in instructions that if it isn't creating a file then the default locations in the registry is messed up but I don't see how.

I do see in my C:/Windows msinfo32 MEMORY.DMP and ntbtlog files that were created when I originally ran the diagnostic tool.

EDIT 2: I used the DM log collector way to get you what you need - attached is zip file.

Because the dumps show the cause to be NETwNs64.sys and the BugCheckCode is 0xDEADDEAD, it is kind of hard to understand what is really causing your error. Our best shot might be running memtest86+ and Driver Verifier.

Test your RAM modules for possible errors.
RAM - Test with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

If it does not show any error, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Information:
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

Warning:
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using http://www.piriform.com/ccleaner looking at Tools > System Restore.

If there is no points, System Restore Point - Create before enabling DV.

Tip:

If you fail to get on the Desktop because of DV, Advanced Boot Options > Safe Mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
If you cannot boot in Safe Mode too, do a System Restore to a point you made earlier.

I will do all this when I get off of work. I have a few PCs so I can run the Men tests right away and let it go through 8 passes like you mentioned. I thought that error had to do with WiFi adapter... I could be wrong but when I did a little hunting it appeared to be my WiFi adapter. Updated that driver as it was way out of date but will still run tests like you mentioned above and get back to you.

It may be the network driver but you can do a memtest86+ anyway and run Driver Verifer thereafter. I'd get a BSOD professional if you want because this is the first time I am helping someone with their BSOD issues. You know, experience comes with practice

I will run the tests and report back - just got home from work.

Just updated the driver yesterday evening and no BSOD or random reboots just yet. Going to run the test that aritra suggested just in case though.

EDIT: And literally seconds after I typed this my laptop locked up on me and I was forced to hard reboot.

EDIT 2: Memtest is up and running will report back after 8 passes or when an error occurs.

Leave it overnight. It will do its job. If it find errors with any one of the RAM sticks, then take them all out except one and run memtest separately on each for 8 passes.

10 passes, no issues. Going to run DV now and will report back.

EDIT: Within minutes of running DV... no BSOD but a random "freeze" where I was forced to hard reboot. Rebooted and DV still running. I'd imagine no dump was created from this random freeze?

EDIT 2: After the random lock up I had two BSODs occur in a matter of an hour. Should I use DM Log Collector to get you the information you require? SF Diagnostic Tool does not create the file after the process is complete.

EDIT 3: I went ahead and got you the zip of the dump files through DM Log Collector as I am assuming you'll need this. Attached.
