Missing Or Corrupt Ntoskrnl.exe But Not Always!

Here is a tricky one. "Windows Cannot start due to missing or corrupt NTOSKRNL.exe".
However we only get the message if something is plugged into the USB port when it is booted up.

It started when the PS2 mouse stopped working. Other PS2 mice did not work either, so it must be the port I thought. So we decided to use a USB mouse, but if we boot with it plugged in we get this message and it won't boot. The same happens with a flash memory key in the USB port. If we boot and then plug it in, it's fine.

I have looked at lots of sites with answers to this problem, but none of them have resolved the problem.

I have replaced the file with another from a different machine.
I have rebuilt the boot.ini file using bootcfg command
I have tried bootfix but not fixmbr, as there was a warning that the MBR was non-standard and it may not work. This may be due to the recovery partition on the hard disk which I don't want to lose.
I have tried another PS 2 mouse, I have tried another Keyboard.

I stopped the problem with a 'system restore' but it came back when I plugged the (USB) printer back in.
Pulling my hair out here! Any ideas?

You'll have to replace the file with the exact same version that was on the system in the first place. That "may" fix it.

Microsoft points to the boot.ini file in this article: http://www.microsoft.com/technet/archive/w...t.mspx?mfr=true

But, since it's associated with your USB ports, I'd suggest updating your motherboard chipset drivers also.
