A7V mbr woes

[hungrypete]

the command fdisk /mbr completely restores the master boot record, right? My A7V has taken a fit of trashing the master boot record when overclocking by multiplier and will not boot windows again unless I clock everything back to default, and run fdisk /mbr. When I try to do this overclocked it either locks up immediately or does absolutely nothing, and the mbr is still trashed. This didnt happen with the old 1002 bios, since I overclocked quite successfully. The only other change is I stuck a silver orb HSF in it and accidentally fatally smashed the thermal sensor. So why the sudden mbr troubles? Any insight?

An orb of any kind can damage your processor. Are you certian that you did not crush your core?

After doing fdisk /mbr you still have to sys C: to reistall the master boot record.

core is fine, silver orbs have special rubber feet that keep it from crushing the core. Unfortunately it IS enough force to smash a thermal sensor🙁

What do you mean sys C:?
whats the actual prompt command for that?
doing fdisk /mbr seems to fix it when not overclocked...
but I am always interested in learning a new "dos-thats-not-really-dos" command!
