    Yes, we have seen that. Many optical mouses have unreliable electrical wiring... they use two internal wires... The worst ones for this are Wireless mouse installs.

    Ok, I am new to these forums. I have a very confusing problem. I use Net Defense firewall, part of SystemSuite 8 pro. I keep getting a firewall message saying that system32 ntoskrnl.exe has done a port scan, that it's a major problem and that it was blocked by the firewall, and that it was a INBOUND scan? Anyone have any ideas what it means by this?

    It means they scanned you, perhaps tried to get onto your system, but were blocked, and no damage was done. They are just marketing how important they see themselves.

    Hi there, sorry to bother you but I am well and truly stuck.

    I have a Dell Dimension 2350, that has recently been coming up with the same error message as above (<windows root>\ system32\ntoskrnl.exe). My main problem is that no system discs came with my PC, so I can't replace the file or re-install Windows. I've tried runningthe various diagnostics that I can get to, and replacing the keyboard and mouse but nothing lets me get past the error message,

    My knowledge is fairly limited I'm afraid. I really don't want to lose on the data I have stored on the hd. Is there any way of retrieving it, or replacing the OS without losing the data?

    New here need urgent help

    Hi there, iam new in this forum.

    Iam from Portugal, sorry about my mystakes writing ... ;)

    After i install SP3 on my Windows XP PROFISSIONAL and after i check that i pc had a virus.

    i install NOD32 to fix the virus ....
    Find 10 erros to solved ...

    After that i install spybot search and distroy them we find 81 entries ... we fiz them all ... after that 2 issues ... restart PC ...


    "Windows could not start because the following file is missing or corrupt:

    <Windows root>\system32\ntoskrnl.exe.

    Please re-install a copy of the above file."

    i read a lot of pages in google, i did a lot of search ... and most of the problems or kind of the problems are solved with a CD of WINDOWS go to repair consulo do this, do that ... and its done.

    I try already do that but after i press R appears a blue screen with a msg that said i dont have a HD :( and i could not go to recovery console ... the only option is F3 and start over again.

    I have a 160G HD SAMSUNG SATA

    i tryit to make a clean new installation on the same HD and the msg is the same when i want to start to install a new OS, u dont have HD ...

    I already o to BIOS and i check that i have HD.

    How can i put into this HD a clean copy of the ntoskrnl.exe ? ?

    Using a BOOT CD with PMAGIC? or used another program to see what happend do my HD ? ?
    or because of the missing ntoskrnl.exe my machine is assuming that i dont have HD.

    i try already to put another HD in IDE and after install XP coud be able to see the other HD ... but i could only see the IDE HD...

    Is is possible anyone helpme? i have a lot of information on that HD that can be deleted :(

    Hello, I am a new user here. I own a HP Pavilion and my OS is Windows XP. I have had the same problems as most above, with "ntoskrnl.exe missing" on startup.

    I followed raybay's instructions, expanded the file, and now when I start the computer, it will go to that screen that reads:

    "Windows did not start properly." It gives me options such as safe mode, starting windows normally, and starting windows when it last worked properly.

    I tried selecting all of these options, and all of them except safe mode go to black screens. When I select safe mode it lists a number of file names, then stops and goes no further.

    I have a restore CD (along with the XP CD) that came with my purchase, but I would much rather prefer keeping my files instead of reformatting and losing them.

    Any help would be greatly appreciated.

    Thanks, Matt

    if the disk u have is capable of doing a windows repair u can do that without loosing any data, but a repair may not fix the problem for long, so backup u're data. insert the disk, go all the way installing a new OS, the second time it asks about installing a new OS after the INSTALL Windows it will give a third option to repair, at this option hit R for repair and let it do its work, it will do everything as if reinstall Windows, but when finished everything will be there. u will have to do windows updates again.

    I also got this error. I had changed from 2 1 gig sticks of ram to 2 2 gig sticks. My motherboard has been a real pain to get this new ram to work. Seems it has some problems dealing with over 2 gigs of ram. I have XP Pro (32 bit). I had always been wondering how much more ram I was actually going to get over 2 gigs. I ended up getting a little over 3 gigs. I had problems setting the BIOS to except this new ram (Corsair). After many failed attempts, I finally got it to work. Played around with it awhile last night. Turned computer off and this morning when I booted up, I got that error. Tried the reset switch a couple of times but computer would just go to black screen. I then turned off computer and back on again. This time computer started to boot and I then got the failed overclock enter BIOS message (the same message I had gotten mulitiple times the night before when I was trying to get the 4 gigs of ram to work). I messed with the BIOS settings again until I finally got the computer to accept the BIOS settings. The computer then booted to Windows without that ntoskrnl error. Beats the hell out of me what's going on here.

    Windows root problem

    I just went through this same problem and did a reinstall and reformatted my computer and did not correct the problem. I found by accident that it was my printer causing the problem. My suggestion to you is to disconnect everything except the monitor, keyboard and mouse and try to reboot, see if this helps. If it does help try shutting the computer and plug one component in at a time. Keep doing this with every component until you find you problem. I also heard that a corrupt keyboard can cause the same problem so you might try a different keyboard.

    Hi RayBay,

    I have tried what you suggested but it does not ask me if i want to overwrite the file.

    I tried the following: copy d:\i386\ntoskrnl.ex_c:\windows\system32

    but it told me access is denied.

    Could help me?

    Ok, I also have this NTOSkrnl.exe missing or corrupt error. If I boot with my USB mouse connected my keyboard is unresponsive and I get the error message. If I boot with my USB mouse disconnected, then my keyboard works and it boots up ok. At that point I can then plug in my USB mouse and all is fine. It kind of looks like a hardware problem to me. All of this re-installing that does not seem to help anybody is a waste of time if it is a hardware problem.

    We've had a few issues qith our PC. We had a trojon horse trying to sell us some anti-virus package, to get rid of that we had to delete rundll32.exe of our C drive along with a few other things. I think i might have got over-excited on the deleting front because now when i re-boot we get the error message window\system32\ntoskrnl.exe is corrupted and needs to be reinstalled. Do i simply need to reinstall Windows XP to get it to work again or can i get around it another way?
