Solved Random BSOD's mostly related to ntoskernel.exe

[suvrajeet]

Hi, I have custom built Win 7 ultimate 64 bit OS system.
Below are my spec:
CPU - AMD FX 8350
MB- ASUS M5A97 LE R2.0
GPU - SAPPHIRE RADEON HD 7850
RAM - 1X GSKILL 4GB, 1X CORSAIR 4GB
HDD- WD BLUE 1TB

I have been getting BSOD's since 6 months now. They will happen for like 4-5 times and then stop. Sometimes they happen more frequently. I tried formatting my system updating drivers(Except for BIOS, pretty scared to do that). Also ran defragment on all the drives and disk check, found no errors. I have attached the zip file as asked by the BSOD posting instruction post, kindly look into it and help me out as they have become irritating now and I have no idea what to do.

Can you try running memtest86 to see if your RAM is failing.
Follow these instructions.

Could not read faulting driver name
[COLOR="Red"]Probably caused by : memory_corruption[/COLOR] ( nt!MiDispatchFault+de )

I ran memtst for 4.5 passes without any error before it got interrupted due to power outage. I didn't face any errors till then. I will be running it again tonight if necessary. But i think it's not related to RAM. Is there anything else I should do?

 

[Thedoctor44]

Well run memtest86 first, lets get failing RAM out of the question.

 

[suvrajeet]

Ran memtest for 8 pass's without any error's. What should i do now?

 

[Thedoctor44]

Right, now I would recommend running Driver Verifier to see if it picks up any driver issues.
Please follow these instructions.

Ok, it seems we have hit the spot. Today while playing dota 2 my system display went weirdie and got stuck with loud weird noise. So I restarted the system but was unable to login as same thing kept happening, so i went into safe mode switched verifier.exe off. After that i did got 4-5 BSOD's. DO make note i didnt get any BSOD"s till i switched off verifier.exe just system crashes. So what should i do next?

 

[Thedoctor44]

Upload those dump files first, lets see if we can pick anything else off.

 

[suvrajeet]

I have uploaded the recent dumps. The last 5 dump's are from the BSOD'd that happened today.

It looks like a network driver is causing issues. It's a long shot but you can try updating your network drivers via device manager and clicking update driver.

Make sure you create a restore point before altering drivers

[suvrajeet]

I tried doing update for network driver but it says i already have the latest version. Do you think BIOS needs update?

Also I just remembered few things:

-In early stages when i started getting BSOD's i had Razor surround installed so i uninstalled it to have BSOD free time for 3-4 weeks.
-Then when i tried to personalize my desktop themes using some open source software's (Don't remember the names now) I got frequent BSOD's, so stopped using them and sticked to basic windows 7 aero theme to have reduction in BSOD's by a large amount.


I am not sure if these things will help at all, but thought should mention them. Also most of the BSOD's happen while gaming and keep reoccurring for 3-4 times. But as it's a gaming desktop and am doing only that mostly, so kind of obvious to happen in those times. If you need any other details regarding any other software like anti virus or something else to do tell me i will try to provide as detailed info as much I can.

You can try running Furmark to see if your video card is failing.
Run it for around 30 minutes.

Follow these instructions.

[suvrajeet]

Ran Furmark for 30 mins, GPU stabilises at 85-86 c...

 

[Thedoctor44]

That's a bit hot but not too bad, it shouldn't cause any serious issues.

Is driver verifier still enabled? Upload any new dump files.
This is a tough one, lets see if we can find anything new.

 

[suvrajeet]

I disabled driver verifier as it started causing frequent crashes as i said in my previous post's quoted below. Didn't enable after that.

Ok, it seems we have hit the spot. Today while playing dota 2 my system display went weirdie and got stuck with loud weird noise. So I restarted the system but was unable to login as same thing kept happening, so i went into safe mode switched verifier.exe off. After that i did got 4-5 BSOD's. DO make note i didnt get any BSOD"s till i switched off verifier.exe just system crashes. So what should i do next?

Also i tried one more thing. Right after 2 months of purchasing this desktop I added a new 4 gb gskill ram. And i think since then BSOD's started. So i just removed that RAM and it's been fine for last 36 hours for now. Not even a single BSOD. Can it be it is causing some compatibility issue with my other 4gb ram from Corsair. For the note both of them are 1600 Mhz ram. And i did run memtest for 8 passes. What do you think?

 

[Thedoctor44]

Yes there can be compatibility issues with different RAM. It won't show up with errors though because it's not faulty.
I think you may have cracked it then.

 

[suvrajeet]

So what should I do now? It will be such a waste of money....

 

[Thedoctor44]

Hmm, you could sell it or keep it. I'm sorry but it's a risk that sometimes we have to take.

 

[suvrajeet]

It's been already 3 days and no sign of BSOD's. Am gonna wait for 1 more day if no BSOD's i will mark this thread solved. Thanxs for all the help.
