Just got the BSOD 2 times in the last hour the information is a Kernal_Stack_Inpage_Error, STOP: 0X00000077. Also had a look in the event manager and it is full of errors;
Source= Service Control Manager
ID= 7000.
I have a feeling that there is something on the PC that is not configured correctly but have no idea how to start checking this out.

Have downloaded debugging tool and the debugwiz tool but could not get them to run.

Any help on this much appreciated.

managed to get the tools working hope this log can help?

KERNEL_STACK_INPAGE_ERROR (77)
The requested page of kernel data could not be read in. Caused by
bad block in paging file or disk controller error.
In the case when the first arguments is 0 or 1, the stack signature
in the kernel stack was not found. Again, bad hardware.
An I/O status of c000009c (STATUS_DEVICE_DATA_ERROR) or
C000016AL (STATUS_DISK_OPERATION_FAILED) normally indicates
the data could not be read from the disk due to a bad
block. Upon reboot autocheck will run and attempt to map out the bad
sector. If the status is C0000185 (STATUS_IO_DEVICE_ERROR) and the paging
file is on a SCSI disk device, then the cabling and termination should be
checked. See the knowledge base article on SCSI termination.
Arguments:
Arg1: 00000001, (page was retrieved from disk)
Arg2: 5d20856a, value found in stack where signature should be
Arg3: 00000000, 0
Arg4: f0895c34, address of signature on kernel stack

Try running Check Disk:

Go to start Run... and type: cmd

Then type: chkdsk /r

You will be told the volume is in use do you want to run chkdsk on next boot? Type: Y and reboot.

Ran chkdsk no problems found, could not read all the printout as the screen cleared itself before I could make any notes. Got the BSOD again yesterday, in the event log managed to copy the following from it;

Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7000
Date: 14/12/2007
Time: 14:59:55
User: N/A
Computer: N/A
Description:
The ZDPSp50 NDIS Protocol Driver service failed to start due to the following error:
The system cannot find the file specified.


After starting my pc just minuets ago checked event manager and it is full of the error’s as noted above. Any ideas how I can get this error sorted.

ZDPSp50.sys file information

Just to check it out you might want to post a HijackThis log over in this other section:

http://www.d-a-l.com/help/forumdisplay.php?f=8

posted HJT Log yesterday, hope it was the correct section? between posting log and today had 1 more BSOD, but it has not been recorded in the event log, the last error event is on the 15th (sat).

If Neal gives you an all clear then return to this thread and we can keep looking.

I just wanted to check out the ZDPSp50.sys issue.

Nothing found with Neal, but since my last post have had 4 bsod, none of them have been recorded in the event manager log, the last error event logged was as before on the 15th (sat).

Run a Search for ZDPSp50.sys on your computer.

Should be: System32\Drivers\ZDPSp50.sys

I am curious who (what program) put this there or is expecting it to be there.

....

Anyway two other tracks:

1) Run the manufacturers diagnostic on your hard drive.

2) Run MemTest. http://www.memtest.org/

How do i run the manufacturers diagnostic on my hard drive?
Have just downloaded memtest, should i wait until i have ran the manufacturers diagnostic before running memtest?
