Over the last 5-6 months my computr has dropped dll files system files i.e system32 folder, program files and drivers. So having been fed up with keep sortingthe same problems out i format the harddrive and start from scratch although this seems to solve the problem for a while it doesn't stop it from happening.
I have checked the harddrive for bad sectors etc and have found none.
I am constantly checking that everything is upto date and if not updating it, but nether the less it happens.
ANY IDEAS
