Windows 7: Random BSOD's

01 Oct 2011   #31

Windows 7 64-bit

Ok so i still get bsods.
I guess it's the motherboard then? As i have had bsods with each of my harddisks disconnected.. before when i only had one hdd i got bsods, then i bought the ssd and installed win 7 on that one, and then i tried to disconnect my old hdd, still crashed randomly.

I've done several tests on my ram including memtest.. errors would show if they were faulty, right? I've run memtest over night 2 times with no errors.

Please tell me if there's anything i have overlooked, thanks in advance :)

EDIT: Or can it be CPU/GPU? Might want to test those again..

It can be almost anything - but it's been 3 months since the last reported BSOD

okey. I'm sorry about your eye problems! Hope it will all sort out

It's not 3 months since i've had a blue screen, i've just been super busy and using my laptop instead, so haven't had time to look at it :/

anyways here are the files:

The perfmon report states that your Cisco VPN is disabled - if not needed, please uninstall it. If needed, please enable it and update it - then disable it again.

Only one memory dump in the uploaded files. If you're using a disk cleanup program, please don't use it until this problem is solved.

Daemon Tools (and the Alcohol % software also) is known to cause BSOD's on Win7 systems through it's sptd.sys driver. Please uninstall the program and use this free tool to ensure that the troublesome sptd.sys driver is uninstalled: DuplexSecure - FAQ - Remove 64 bit sptd.sys

Please update these drivers, paying particular attention to those highlighted in RED:
- Create a System Restore Point prior to doing any of this. DO NOT mess with the drivers themselves - leave the Windows\System32\drivers directory alone unless we specifically direct you to it!
- Please update these drivers from the device manufacturer's website - or uninstall them from your system. Reference links are included below.
- DO NOT use Windows Update or the Update Drivers function of Device Manager.
- Please feel free to post back about any drivers that you are having difficulty locating.

If the BSOD's continue after this, please run Driver Verifier according to these instructions:
Using Driver Verifier is an iffy proposition. Most times it'll crash and it'll tell you what the driver is. But sometimes it'll crash and won't tell you the driver. Other times it'll crash before you can log in to Windows. If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.

So, I'd suggest that you first backup your stuff 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).

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Special Pool" and "Low Resource Simulation" and click "Next"
NOTE: You can use Low Resource Simulation if you'd like. From my limited experimentation it makes the BSOD's come faster.
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

Reboot into Windows (after the crash) and turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page, then locate and zip up the memory dump file and upload it with your next post.

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

If that doesn't work, post back and we'll have to see about fixing the registry entry off-line:
Delete these registry keys to stop Driver Verifier from loading (works in XP, Vista, Win7):
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDrivers
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDriverLevel

Windows 7 64-bit

Ok. I updated many of the drivers (the ones i could find) and deleted and used the tool to remove Daemon Tools.

Then I installed Pro Tools, need it for some of my music recording, and it seemed like it just made everything worse, so I removed it again, to solve my computer problem first.
Many of the crashes seem to be caused by the anti-piracy software in Pro Tools.

So i removed it, and still get blue screens. I have been running with driver verifier running.

I also find a weird huge file that appeared on my secondary hdd: "DUMP1d20.tmp" modified two days ago.. do you have any idea what it is, can i use it to debug or something?

One of the minidumps said something about some memory failure, so i tried to run memtest again. After two passes it showed some errors, but i tried running 5 more passes the next day, to see if i could reproduce the errors, but it showed no errors this time.

I'm uploading a big bunch of dumps and a new perfmon report in case you need it

Windows 7 64-bit

ok i tried to run prime95 as suggested in another post you wrote earlier, where i told you it found something but we never really looked into it.

I get the same error as then, after like 5 minutes there's errors on all the "workers"

What size is the "DUMP1d20.tmp" file?

You've got memory errors - both using MemTest and using Primer 95. While bad RAM is the most likely cause, please run all 3 tests of Prime95 (Blend, Small FFT's, Large FFT's) and time how long it takes for each to generate errors. That'll give us a clue as to what's causing this.

FYI - I can't see well enough to read the memory dump files. If my suggestions don't fix it, please PM another staff member for assistance.

Windows 7 64-bit

The "DUMP1d20.tmp" file is 4.44 GB

The blend test takes as little as 20 seconds to 7 minutes to fail.

The Small FFT's test didn't show any errors after 3 hours (had to shut my pc down, it's so noiseful!) Do i have to have it running for a longer time?

The Large FFT's test showed errors in less than a minute to 5 minutes for 3 of the workers, but it took 41 minutes before the 4th worker got an error.. how can this be? :)

Thanks again for all the help so far, I'm really sorry about your eye problems.

I suspect that the .tmp file is a remnant of a crash that wasn't completely captured.
How much RAM do you have?
Check the date stamp on the file and see if you can recall any crashes that weren't completed that day.
Rename the file to .dmp and see if you can open it in WinDbg - that may give you more info (if it opens)

FWIW - MemTest doesn't stress the RAM when testing - Prime95 does stress it.

Blend test tests a lot of RAM, Large FFT's also tests RAM. I'd suspect that the RAM is bad (although it's possible that it's something else). Try testing each stick and each slot individually - to see if it's just one stick or not. Most brand name RAM has a lifetime warranty - so you may be able to get yours replaced. If not, purchase RAM from a place that you can return it for your money back.

Windows 7 64-bit

I have 8 gB ram (4 times 2 gB)

I tried renaming the file to .dmp and could actually open it in WinDbg. It was an 0x10D error and it points to MDPMGRNT.SYS which is one of the drivers that came with Pro Tools.. i don't remember any crashes that didn't complete but well.. might just have forgotten. There's not much help from that file, i guess.

Suspecting the RAM too. But could be the ram slots or something.
In the weekend I'll try testing each ram stick and slot like you suggested.
