Hello,

I am using sandboxie 3.64 with win 7 32.

I have all browsers sandboxed by default , and the folder location is on external usb hard disk

The problem is : I have a blue screen when restarting the computer .

The problem in details : Before restarting First i terminate the sandbox and make sure that the sandbox folder is erased... then i restart the computer and just before the computer loads there is a blue screen and the

computer restarts.

My solution :Before restart ,after erasing the sandbox , I run all browsers out of the sandbox to let windows know that their folder location is on the main hard disk : c ... , and then i restart the computer and all is fine ...

no blue screen .

Explanation : i remember before the days i had sandboxie, i moved the internet explorer folder location to a usb external hard disk ( to catch any harmful virus and shut the external hard disk on time )

If on startup the folder location was denied i would get the blue screen .


My suggestion is that on sandboxie termination there would be some kind of a operation to let windows know that the folder location is back to c .... and not in sandboxie folder location.

I think this concerns only to internet explorer .

Until you upload your memory dump for further scrutiny, it's pure specualtion as to the cause of the bluescreen you're experiencing.

O.k, tell me how to do it ....

But there is one truth - the problem is solved when doing the steps i described.

Windows can make mistakes in its log... since its a blue screen ... windows doesnt know what to do ... it will only tell you the last thing it was

trying to do.

There is another way to validate this ... The error can be repeated by anyone .

I don't think this problem can be repeated by anyone. It is probably a unique condition on your computer, perhaps a conflict with some other software. If you upload the memory dump from the crash, it might contain some hints about the problem.

Look in your Windows\Minidump folder to see if you have any recent dump files that match recent blue screen crashes.

On an unrelated note, I noticed you post some of your problem reports in this Anything Else forum. In the future please post them in the Problem Reports forum. That helps to keep this forum a bit more organized.

DMP file :

skydrive shorten url :

http://goo.gl/E0D1K (url was taken out)

What i am saying is that anyone who uses this method more then a month will encounter the blue screen on startup.

From there its only by my method to load windows.

Or to find a way to connect the external hard disk before windows starts , and thats not possible always.

Although I'm not ruling out some contribution from Sandboxie in this problem, your .dmp file blames the nVidia driver NVLDDMKM.SYS for the crash.
An Internet search for that driver name turns up a lot of blue screen reports. The ones that I read recommended to update that driver.

I dont want to disrespect ...

But this is a false blame.

This is not the source . It always blames this driver , no matter what happens.

My guess is that it tries to enter the external hard disk and then there is a failure, so the next immediate thing when its in the stage of

loading the nvidia driver , it fails , so there is an error in loading the nvidia driver , so that is what is written in dmp file.

The missing external hard disk is not a failure in a driver software ... there is nothing to write here in the dmp file.

I am long experienced with reading the event viewer with regarding to the nvidia driver. (from xp till today)

90% of the boot blue screens are reported beacuse of of the nvidia driver . no matter what is the real cause .

and no matter the fact that the nvidia driver is updated or not.

Still, if you have old graphics drivers that have associated crash reports about them on the Internet, you should probably upgrade the drivers and see if that makes a difference. There doesn't seem to be any other direction to explore at this time, so perhaps you would consider giving it a try.

Sorry ,

I have many years experience with my nvidia drivers.

They are not the cause , just the the symptom.

All that is said .... i cant update these drivers because the new drivers uses open gl 3 which is not compatible with my graphics card.


Anyway , the problem is gone when i stop using sandboxie on an external usb hard disk.

....problem may be solved when i move to esata ...

It is possible that the external usb (ide) hard disk enclosure is giving its goodbye signs .

Hope the problem stays away -- but if not, it could also be an intermittent hardware failure of the graphics card. That would crash a perfectly good driver. This is very difficult to tell from a software problem, and tzuk says he can't see how to pursue that any farther.

Is it only the blue screen, or does your monitor ever go black? If it comes back after a second or two, that would be the operating system restarting the driver. Supposed to do that, and it would, if the electrical intermittent had disappeared in the meantime.

A hardware intermittent on your card would also cause a driver's file name to appear on your dump (I believe it's already there?), and likely on your blue screen error message as well. Windows 7 has some pretty specific messages in its error logs. Could be worthwhile to see what they say, as all this should be being recorded.

Is the conductor side of the graphics card pointed up, inside the case? If yes, is there a mat-like layer of dust and lint sticking to it? Blast it clean with a can of residue-free electronic cleaner. Give the contacts a blast while you're at it. If the card has a fan, is it spinning normally?

Graphics cards run hot, and heat is the enemy of electrolytic capacitors. The hotter the board is, the shorter their useful life! What do your card's temperature sensors indicate?

Does your graphics card have electrolytic (vs polyethylene) caps? Any evidence of swelling or leakage? If yes, these can be replaced, if the cost of an equivalent new card would justify it. New replacement caps, likely of better quality than the originals, may be had for less than $10 per set (depending on how many you need), postage included, plus your own labor.

Don't have the operating system set to restart following a crash when you're troubleshooting a problem ... because then the bluescreen disappears before you can make a note of what it tells you.

Windows 7's bluescreens are more informative than those of previous versions.

Thank you very much for all the people who tried to help ... Including Tzuk of course ...

I will take away my DMP file because this is going too far ...

I will just add that i am a professional hardware person ... and i dont take back any word i wrote here .

Somtimes things are not what they seems.
