Memory Access Error

Win98SE installed on a clean hd.  Occasionally, while either attempting to load software OR by virtually leaving the machine alone the error message appears: 0028:c0035525 in vxd ifsm gr  (01)00002c51. Additionally, though I don't know if it's in any way related, the computer will re-start on it's own.

CAUSE
=====
 
This behavior can occur if the Vhpscand.vxd file is located in the
Windows\System folder instead of the Windows\System\Iosubsys folder.
 
RESOLUTION
==========
 
To resolve this behavior, follow these steps:
 
1. Click Start, point to Programs, and then click Windows Explorer.
 
2. On the Tools menu, point to Find, and then click Files Or Folders.
 
3. In the Named box, type "vhpscand.vxd" (without the quotation marks), and then
   click Find Now.
 
4. If the Vhpscand.vxd file is located in the Windows\System folder, right-click
   the Vhpscand.vxd file, and then click Cut.
 
5. Right-click the Windows\System\Iosubsys folder, and then click Paste.
 
6. Restart your computer.

Did as you suggested.  The file vhpscand.vxd is not even on this computer.
What next?
To 1cell: The file in question is not on this drive so I must reject your answer.  Thanks for trying to help and being so prompt in posting your answer.

This question has a deletion request Pending
This question no longer is pending deletion
it needs to be!

extract it from the 98CD using System file checker.  Extract it to the Windows\System\Iosubsys folder.
 
to run system file checker, go to start | run | and type SFC and hit OK

then select to extract one file from CD
1cell - I checked three different computers, all pre-loaded at the factory with Win98SE, and two of my own computers, also with Win98SE, and this file is not to be found.  Additionally, I performed a search for the questionable file on two different Win98SE CDs and it's not there. Now what?
Don
this file will only be found on a system with a scanner attached/installed and you will have to extract it from the CAB files.  This is why I recommended SFC since it does not require that you know which CAB file the actual file is located in.  you will not find this file by browsing the CD.
Since the computer in question doesn't have and never has had a scanner attached/installed why would I then look for this file?  Additionally, please remember that I installed a new drive on this machine, loaded SE, and nothing else, and immediately started receiving the 0028 error message (aka the blue screen of death).
Where next?
Note: I have the SE cab files in a folder on the hard drive for reasons such as this.  When I run SFC I have it set in the Registry to automatically point to this folder and it still couldn't find the file.
why would I then look for this file?

because the about the only instance of your EXACT error found in MS Technet relates to a problem with the control panel which is usually caused by scanner software.

 I have the SE cab files in a folder on the hard drive for reasons such as this>>>>>
you mean all the CAB files from the CD and not just the ones which are copied over as part of the installation process, right?

Two facts (clean install and error with memory management) make me think that this might turn out to be a memory or motherboard drive problem but there are a few other possibilities.

first, give me some more info:
What software has been installed?
What is the hardware config?

when you mentioned that the computer will restart on its own, when does this happen?  Is it when this error occurs?  While on the internet?  While gaming? random times?  This could give us a clue.  There are many reasons a computer could restart on it's own but if we can eliminate any, we might find that this is a memory or motherboard problem.
you mean all the CAB files from the CD and not just the ones which are copied over as part of the installation process, right?
Yes, I always copy all of the cab files to a separate folder so I don't have to go looking for the Win98 CD.
On the off chance that the installed 64 meg of ram had somehow worked itself loose, I removed and re-seated the ram and the computer has not restarted since I posted this question.  If fact it's been running non-stop for 5 days so I now believe the re-starting problem is a non-issue.
Computer specifics:  Pent 166MMX, 64 meg of ram, 4 gig wd hard drive,ext bus pci 2.10, bios: american megatrends, chipset intel 430vx, triton III, soundblaster audio,  video card s3 virge pci (325), us robotics 56k modem.  Unit was custom built by another company a couple of years ago.  The ONLY application on this computer when the 0028 problem occurred was WIN98SE. HOWEVER, I do remember installing Win95 initially to see if that would eliminate the 0028 problem, but saw it then as well.  BIOS related?
Lastly, I have not seen 0028 again, since I posted this question; naturally.  Hope this helps.

haha, I FIXED IT!!!  just kidding.

But I think I've figured it out after researching the scanner problems a bit more.  It seems that there is a PCI/IRQ steering problem with some chipsets (including VX) that was causing conflicts and I found it with other hardware like network cards, modems, and a few others.

I've experienced this problem (and it does cause rebooting) first hand here at NEC while working with some newer systems we were trying to figure out and the solution turned out to be fairly easy in most cases.

Move whatever is in the first PCI slot to another slot.  That usually solves it.  

If not, remove the modem and sound card and verify that things are working OK.  If they are, then manually install the sound card with reserved resources in device manager and test again.  If everything is ok, plyug n play the modem.

In the case that this does not fix it, try a BIOS flash.  Unfortunately, you wont get a very recent version of BIOS for the VX chipset.
1cell -haha, I FIXED IT!!!  just kidding.
You must have gone to Den's/Dew Associates school of humor.  Heh, heh, right back at ya.
I'll go ahead and try what you suggest, but it'll take a couple of days to see if this solved it.  I'll let you know.
Thanks,
Don
1cell - Well, moving the modem from the first slot didn't solve anything, but guess what?  Removing and installing another modem did.  Make sense to you?
Don
which other modem?
Took the older 33.6 US Robotics out and put in a new Boca and it seems to work fine.

1cell, seems like that was in fact the problem.
Thanks,

hey, glad I could help.  Must admit, I'm a bit suprised but I've seen a million things go wrong with PCI/IRQ steering including spontaneous reboots.
A great advancement huh?  kinda like USB!

Gosh, don't get me started on that.  I finally quit using my usb connection on my HP6200 scanner and had to go to SCSI because every few days the computer forgot I even had a scanner.  Go figure.
