Massive amounts of BSODs on boot, multiple errors; BE, 18, 7E, 0A

Hello Windows 7 Forum,

I work at the IT department of a school where we have around 600 PC's that need to be maintained. Most things break by the kids and most is fixed my replacing, or simply imaging said computers again.
However, after having switched over from Windows XP to Windows 7 we've been having masses of BSODs when loading Windows. Not just the normal PC's, not just linked to one type (although pretty much everything is from HP). But it keeps happening.

The most common errors that we've been able to discover are:
0x00000018, 0x0000000A, 0x0000007E, 0x000000BE
After having researched these things, they all turned out to have something to do with drivers, not only that, but when trying to boot into safe mode the PC's would all freeze at "classpnp.sys" and sometimes reboot shortly after.

Our current solution is simply putting a new Windows 7 image over the computer and it'll work another day or two. It's great that it works again then, but we spend too much time on it.

As thus I come here, I want to avoid this problem. It can't possibly be the hardware, there are too many different kinds of computers for it to be that. I'm quite sure the problem is somewhere originating from the drivers we install, but then he question comes as to what ruins the drivers? Not to mention that there are also different drivers for the different kinds of PC's.

If I'm lacking any information please tell me. Thank you for your time.

Hello Alpha, welcome to SevenForums!

This is going to be relatively tricky for us to help you with since it's on such a massive scale of computers. Is there any possible way you can grab a few dump files from any computer? Regardless, would it be possible for you to get one of the school PCs to boot into safe mode? If you can, see if it stops at CLASSPNP.SYS when it's loading all of the drivers.

Since you've mentioned ever since your school moved over to Windows 7, the issues started happening, I doubt it's a massive hardware related issue, but probably a bad image that you guys are using to install. Have you guys tried a BRAND new image / disc to see if its the current that is at fault?

It indeed locks up on classpnp.sys when booting in safe mode, I should have been more specific, my bad.

Otherwise, I'm not entirely sure how to make/get a minidump or do anything that's described in the instructions topic seeing I don't get into windows at all. I suppose I could get the HDD of the BSODing computer, I shall do that now.

As further information, I've also had a few computers, 4 so far, where the date reset to 2099. This is an issue that has come over the last week while this issue has been going for at least 3 months now. I'm not sure if this is related, but I figure any additional information is helpful.

I'll post again once I retrieved the dump file.

Sounds great

The date issue you mentioned, does the time switch as well? Those can just be a dying CMOS battery, simple and cheap fix.

Great, the forum just ate the reply I put in Quick reply, let's do this again, but shorter.

I was able to connect the HDD to my computer and had to turn it online, after that I was able to locate the MEMORY.DMP file, but it's a whopping 150mb. I'm quite sure that I shouldn't upload that much. I saw that I could adjust the memory dump file size to 256kb, but alas, I can't boot into windows to change this. Is there some configuration I could edit for it to change to that?

As for the date thing, the time was indeed off on 3 out of 4, I'm guessing the 4th got lucky with being turned back on at the right time or something. Either way, if it's indeed just the CMOS battery the solution would be nice. The sudden 4 in one week is what concerned me though. I thought it might have been related.

Anyway, my working day has come to an end, I'll return tomorrow, with hopefully a smaller memory dump, or a way to get the small out of the bigger dump.

The reasoning for it being that large is it is likely a full memory dump rather than a small, it contains much more information, thus the increase in size.

Sounds good man, keep us updated with any further information

Well, after a lot of hassle I found out that windows automatically saves minidumps as well. Yay for not readings things properly. After that I tried finding a program that would let me read the thing, but it redirected me to some windows thing that wouldn't let me download anything and I needed to get some subscription.
Then I also figured that I wouldn't know what to do with said decoded minidump file anyway, seeing I already know which codes it got.

So either way, uploaded it to dropbox, and here it is, please tell me you can figure out more than me.

EDIT: Well I finally got something through google, here's the debug report thing.

REFERENCE_BY_POINTER (18)
Arguments:
Arg1: 00000000, Object type of the object whose reference count is being lowered
Arg2: 85c81a88, Object whose reference count is being lowered
Arg3: 00000002, Reserved
Arg4: 89a6df88, Reserved
    The reference count of an object is illegal for the current state of the object.
    Each time a driver uses a pointer to an object the driver calls a kernel routine
    to increment the reference count of the object. When the driver is done with the
    pointer the driver calls another kernel routine to decrement the reference count.
    Drivers must match calls to the increment and decrement routines. This bugcheck
    can occur because an object's reference count goes to zero while there are still
    open handles to the object, in which case the fourth parameter indicates the number
    of opened handles. It may also occur when the objectís reference count drops below zero
    whether or not there are open handles to the object, and in that case the fourth parameter
    contains the actual value of the pointer references count.

More than a week has passed, has anyone gotten the chance to look at this?
The problem still occurs on many computers.

I'm not quite sure how to follow a guide that tell me to do things on the computer when I can't even boot the computer into windows, which is the whole problem here.
And I'm quite sure that doing all those steps on a functioning PC is not going to help.

I already uploaded the minidump file and the added information. Is there anything else I can obtain?

Everything is being run on a Windows 7 Enterprise x86, there's several different machines. Ones that were designed for windows 7 and others that aren't supported by HP itself anymore seeing they were made for XP, we did however at least put in the minimum required hardware in the older machines.
