Hi all thanks for taking the time to read my problem.

I have a P4 3, 2 GIG ram, 2x120gig hd, Raid, running 2 x 180 GIG drives, TV card, Radon 9600 Video card, on board sound, Netgear wireless card, etc. Running XP Media edition.

I use this computer as a Multi Media PC and it serves Movies & Music to my lounge using Neuston MC500 media player. All worked well.

One of my HD failed and of cause it was the one with the OS on, so I put a new drive in and reloaded my software. All appeared to be running well.

I bought 2x SC101 Netgear storage centres and put in 2x250GIG and in the other unit 2x180gig drives, formatted and are also working fine.

For some reason ever so often when I am using my MC500 I can be watching a movie and my computer will restart and I don’t know why. It does a memory dump and I have attached it here for your help.

It does not happen if I am listening to Music and only happens when I am watching a movie.

I don’t know if it an issue with the SC101, Video drives, but the MC500 is inderpended to the video card, and the pc just serves the data to the box, or if it is a Memory issue.

I get the following on the blue screen.

page_fault_in_nonpaged_area SFSZ.SYS - address AC53F452 base at AC50A000, Date Stamp 4354344C.

The computer writes a memory file in which I don’t under stand. I have done searched on the net and I can’t find an answer.

So if anyone can help I would really appreciate it.

here is the memory Dump.

Please check the Event Viewer for the event ID numbers linked to the problem:

1. Right-Click My Computer and select Manage.
2. In Computer Management, click Event Viewer and then double click System.
3. Write down the event ID and description for any errors (those with a white X inside a RED circle).

Let us know what the ID number and description is for each error.

Hi Doc

Thanks for you quick reply, I have looked where you suggested, but there is no report at all.  A few seconds before the computer crashes, I hear a bonk, bonk, like windows has a problem and if I have my computer open showing the drives from the storage center I hear the noise and then they disapear then the memory dump starts.  I am sure that it is not a problem with my MC500 Neuston music center, and the problem has only started sice installing the Netgear SC101.  BTW I have contact Netgear, and I am on a 10 day wait before they look at at.  I did manage to found out that the file that could be causing the crash is made by dataplow, incorporate and that it is a SAN File SYSTEM (SfS)  what ever that is and the File version is 3.41, so I have sent an email off to them and they have asked for a memory dump which I have supplied, so i am waiting to hear from them.  So i really dont know where to go from here.

Regards

Derek
