RE: isapnp.sys - ntfs.sys missing or corrupt - Toshiba




Hi Alec,
My Guess it will be the RAM is bad, finger cross is that easy.
If the test gone okay, try to scan this HDD before trying the Recovery
Console by using the Recovery CD.
Error Message: The System Has Recovered from a Serious Problem
http://support.microsoft.com/kb/316424

You receive a "Windows could not start because the following file is missing
or corrupt: Isapnp.sys" error message at startup
http://support.microsoft.com/kb/315311
If the Recovery will help in copying then you can get the Same XP CD (borrow
one) and copy the files to its directories per the KB above.
HTH.

Thank you. Forgot to mention that I took out the HD (Hitachi Travelstar
http://www.hitachigst.com/portal/site/en/menuitem.ef1eac5265e3375befca8644eac4f0a0)
and ran the Hitachi Drive Fitness test on it: test completed without errors,
so I assume the HD is fine.

At one point I did manage to get Windows to start, but seconds later it
displayed following Microsoft error (I shot a photo of the screen just before
it blackened):
Error signature (displayed on 2 lines on screen):
BBCode : 1000007e
BCP1 : C0000005
BCP2 : EE8B3ED6
BCP3 : EE9F7C6C
BCP4 : EE9F796C
OSVer : 5_1_2600
SP : 1_0
Product : 768_1

I had made no hardware or software changes before this problem occurred.
I'll now check RAM with the suggestions in the headers you kindly pointed me
to.

Context:
Windows XP Home Edition pre-installed on Toshiba Satellite 60 laptop (sold
only with Toshiba A60 Product Recovery DVD-ROM)

Problem:
- Cannot start Windows (even in Safe Mode), system stops with either one of
following black screen messages:
"Windows could not start because the following file is missing or
corrupt:\windows\system32\drivers\isapnp.sys"
"Windows could not start because the following file is missing or
corrupt:\windows\system32\drivers\ntfs.sys"
- Cannot tell whether it is hardware- or software-related.

Tried out following, with no result:
- Laptop taken to pieces and cleaned; CPU cooling grease replaced
- CHKDSK by forcing boot order to an external floppy(no problem reported)
- Booting from XP boot floppy disk (courtesy www.bootdisk.com)
- Took out HD and connected it to a second laptop to replace isapnp.sys and
ntfs.sys with more versions copied from other computers
- Changed boot order in BIOS setup page

Are any of these worth trying?
- I have also not managed to get to the BIOS command line at any level. Is
there a
specific key combination for this?
- Take out the HD and connect it to a second laptop and run the XP OS
through the USB port? Would that be a problem for the second laptop’s OS
(Windows2000)?
- Use a new AC Adaptor (does it have to be Toshiba or can I use any Adaptor
with the same?)

Toshiba retailers tell me I have to buy a new WinXP CD, which I do not want
to do, since I have already paid for the one pre-installed on the laptop.

Thank you
