Again, I should have explained my situation better.
The harddisk from the server made some strange repetative noise for a while and then the machine started to reboot by itself. This was the second harddisk in roughly two weeks, so the conclusion was that the crashing harddisk was the result from another failure.
A decision to replace both harddisk and mainboard was quickly made. I managed to copy the content from the crashing harddisk onto the new one (thank you http://www.hdclone.com
) and connected it to the new mainboard from a different manufacturer.
The new PC would not boot into Windows (as expected ofcourse), so trying the option from mr. Langa could not do me (more) harm. After following the instructions to the letter, this system now not only boots into Windows, it does this very fast (1 minute with quickboot disabled in the BIOS).
Because of all this, I thought the method could work wonders for the slowly booting machine from Curt.
You are right about the necessity from an occasional re-installation f0dder, but I try to postpone that for as long as possible. My day-to-day PC is running for three years without a re-install and I do a lot of software "play-testing" on that PC.
