I have a system that has windows XP pro loaded and when the user logs in the syetem will restart.  I brought the system to lab to work on it.  Booted it boots fine and just left it to sit and then it rebooted on its own.

Got the system into safe mode and it works in safe mode not well but well enough for me to uncheck the reboot option so I could see if there was an error.  

Sure enough "page fault in non paged area."  Pulled the minidup and looked at it. It indicates the driver CLASSPNP.SYS caused / causing the crash.

I checked the memory and it checks good

I substuted an old backup copy off the system while in safe mode that did not work.

Would really appreciate some help on this one.

You may have a bad hard drive. Try running the manufacturers built in diagnostics. You can also try running chkdsk /r /f

The disk check out ok this is a powerEdge 440SC.  The stop error is 0X00000050.  Looked it up and it indicates some kind of RAM issue.  

Took all RAM sticks out and I get a 0X0000008e issue which again points to a RAM issue, but I am not so sure.  

Is it possible the L2 cache on the CPU is bad.  That might explain why it works very slowly in safe mode.  It does not work the best, but the system does work in safemode.  The system is running windows XP pro.  I know what is a workstation OS doing on server hardware - unknown

Did the Dell diagnostics program detect any memory issues? Do you have the Dell disc that allows for the graphical diagnostics?

Is the new RAM compatible with the computer? How many RAM slots do you have? It could possibly be the actual RAM slot giving you issues. Put a stick in one slot and leave the ramaining slot(s) empty reboot and try again. Try the next slot if the error still occurs. Try a different stick. Try every possible combination.

The actual windows operating system is damaged in some way.  

I put all the memory back in and I loaded windows 7.  windows 7 loaded and down loaded up dates with out issue.  So, I would think that would rule out hardware.

I ran ERD commander from Technet and it did not find any corrupt system files, so I am wondering if they have a rootkit or virus that is doing this.

Does anybody know of a nice safe mode AV scanner I can use to see if it is infected with a rootkit or Virus?

thanks much,

Rick

Norton Power Eraser has a simple interface featuring three large buttons: Scan, History, and Settings. The Settings include an optional Rootkit scan. It does require an Internet connection to grab the latest definitions before scan. I don't know if it runs in safe mode.

I fixed it.  The issue was a rootkit.  Pagefault in non paged area.  The AV was old and outdated got rid if the root kit using kaspersky tssd killer.  Ran an AV tool found a few more the system run like a top.

Rick
