What a coincidence. I am talking with someone else on another thread about a "driver"
which we know is loading from the bootlog, but cannot see the file on the disk -
exactly the same thing! In his case, I'm fairly sure that we are looking at a rootkit
infection due to other obvious symptoms i.e. taking an age to startup. In your case
I am not so sure since the original symptoms of rebooting etc have been cured with
a good clean-out of the PC to prevent overheating. I am still suspicious that you
have something bad lurking on your PC, so please monitor it for any unusual behaviour.
If you also have a rootkit infection there, be aware that cleaning these things up
is not for the faint-hearted! Cheers. Spexx.
