"C:\windows\system32\drivers\ndi.sys is open or in use by...

by Michel Petrucci / February 13, 2009 8:19 AM PST

I followed Robert Profitt 's last advises and re-installed windows. but I cannot install "Norton Internet security" again because it needs the Win SP 2 or Higher. The problem is that when I try to install the SP2 or SP3 I have always this error message: "the file C:\windows\system32\drivers\ndi.sys is open or in use by another application. close all other application and than clic Retry.
I don't have any other application opened because I have'not installed anything else yet. except the necessary drivers..
Thank you so much if you can help.
Michel.

Solution= You certainely have more than hard disk.
by Michel Petrucci / April 25, 2009 3:54 PM PDT

Hi elite331. I have finally resolved that issue. In fact the problem was an "hidden virus" in the second hard disk. When you Have more than ONE Hard disk (witch was my case),The virus was in the SECOND HARD DISK (hidden in a "file") and of course even I tried to install into a brain new formatted disk, (even in Safe Mode) I allays been stopped by the same message error that I/you had. SO, first DISCONNECT THE SECOND HARD DISK from the mother board and install Windows (from CD), than the services packs, than install first of ALL Your Norton product.
When Norton installed, re-connect the second hard disk and scan it.
It has worked for me. Good luck.

But maybe your 120 GB is partitioned ?

In reply to: RE : Solution

Hi elite331, Its definitely a virus. Thats is sure. Maybe your 120 GB disk is partitioned? and Maybe you have data's and others files, images, setup programs (witch contains the virus).. on the 2nd partition? Anyways if is the case and if you don't succeed, I suggest you to backup that partition and format it. Than install WinXP into a clean formatted partition an than the SP2-3 but FROM A CD.
Or spend few more dollars and buy a 20-40 GB hard disk and just use it for install and run Windows XP.
You know, before I found the solution I have searched all forum and I have re-installed WinXP at least 5 times. I NEVER THOUGHT THAT MY SECOND HARD DISK (infected) COULD INFLUENCE ON THE MASTER DISK.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
