Blue screen: Page_Fault_In_Nonpaged_area

[sg007]

Hello, guys. Very new here, with wierd problem.
I tried to find the solution on past posts, but no success.

I have a laptop, running WinXP Home. Yesterday, sudenlly happened blue screen, with following message:

PAGE_FAULT_IN_NONPAGED_AREA
***Stop: 0x00000050 (0x87821D95, 0x00000001, 0x80572D06, 0x00000000)

After restart, just before Windows was completly loaded, it happened again.
SO from now on i cannot boot anymore, or use it.

Tried to find the solution, no success.
Any hint what can be wrong? I start computer with BartPE, checked it with antivirus, spyware - nothing. Running test for hdd - all ok.

Now im working on Window console with repair function, but even this not working. Now running "chkdsk /r", will see what will happen?! chkdsk /f /r not working, /f key want to force hdd... and i dont know what that means....

I think its s/w problem, not h/w or memory.

Thanks for help!

Why do you think that it is not memory? Have you tested the memory?

 

[sg007]

Not yet memory

No, i did not test the memory (yet).

What program i can use for testing the memory?
I cannot come to WinXP, before all programs are loaded, i got blue screen.

Only in DOS i can do memtest.
What do you reccomend?

thx

Memtest86 can be run from a DOS boot floppy or from a bootable CD

 

[sg007]

Memtest86 ok

I d/l Memtest86, made bootable CD and run the test.

It passed ok, all tests. No errors found.

After restarting WinXP, i still got blue screen, this time little later then before, but another STOP message:

*** STOP: 0x0000007E (0xC000001D, 0x8057459E, 0xF7260B10, 0xF726080C)

Then, the following message comes up (it is in german language):

"SPEICHERABBILD DES PHYSISCHEN SPEICHERS WIRD ERSTELLT.
SPEICHERABBILD DES PHYSISCHEN SPEICHERS WIRD AUR DATENTRAGER ERSTELLT: (xx)"

There, where is xx, means timing. Seems that computer wants to write "memory capacity" on hard drive, but somehow it cannot.

Before that i got error:
PAGE_FAULT_IN_NONPAGED_AREA
***Stop: 0x00000050

like i mentioned before. Now seems other problem. Maybe that is because i install WinXP again, as R option (repair). Anyway there must be a driver problem, or maybe corrupt in registry.

Safe mode does not work, if i choose that, computers restart itself over-n-over...

Maybe would be better, if i only reinstall WinXP as fresh copy. I am only sorry for many data, i cannot save them... other then remove hdd, put hdd in ext. case and copy to other computer.

If any other hint, please help :/

Thx, guys!
