First things first. Do you at least reach the login screen? If not, exactly what happens when you try to start the computer?
Shamil MohamedIT Infrastructure Engineer/IT Systems ManagerAuthor Commented:
Nope, couldn't reach login screen. after boot up its end up in troubleshooting mode. log file report after system repair telling ndis.sys is corrupted.
Shamil MohamedIT Infrastructure Engineer/IT Systems ManagerAuthor Commented:
If can reach login window I could have backup required files and would do reformatting.
nobusCommented:
what about a repair?
flubbsterCommented:
If it is in troubleshooting mode, then I assume you are at the Blue Screen. From there, you can try doing a system REFRESH, not a RESET. A refresh will repair the operating system while leaving your data intact.
Shamil MohamedIT Infrastructure Engineer/IT Systems ManagerAuthor Commented:
Refresh also didn't help.. It's failed and back to advanced settings.
flubbsterCommented:
The only thing you can try then is a RESET. As I said, you will lose everything on the system after doing a reset. If you are able, pull the drive and connect to another PC with a SATA-USB adapter and pull any files that you want.

Bro.. Actually ndis.sys troubleshoot feedbacks are not much available in google also.
I found that it's because of hdd bad sector. Now in the process recovering files.

But I am considering of troubleshoot also which will help in future.

Thank you.
flubbsterCommented:
Hope you can get your data then. Good luck. Let us know how you do.

>>  I found that it's because of hdd bad sector.   <<  then run the manufacturer's diag tool on it; i use the UBCD for this:
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

**  you can make a bootable cd - or bootable usb stick

According to hdd bad condition every process taking very long time to finish.
So I decided to use "robocopy" to move/backup the users files to new pc.

I didn't any effective way as downtime allot.

Thanks for your support.
