just a general statement that will apply to most peeps PC, esp with windoze.
i reckon that after about average 9 months use, you will notice a decline in the speed of the pc, and more and more problems generally.
a clean fresh install will clear out all the garbage.
also a good idea to partition your drive into say 3 drives.
keep all your files on the D drive. and backups onto E.
use C just for the OS.
and remember to backup anything really essential onto other media. ie a cd. they cost about 10p each!
or use an online storage facility, ie photobucket for your piccys. or yahoo
etc...
also with the price of a hdd being about the same as a night out, it makes good sense to have a second/spare hdd.
domestic users are one thing, a hdd failure is not usually a major event. business users are another matter entirely. yet the number of companies that dont backup regular, (if at all!), is just amazing!
small business users are the worst offenders.
remember. there are 2 sorts of peeps with a PC. those who have had a hdd failure/major OS crash, and those that havent yet.
