I had a computer given to me, that I want to clean out, nothing on it is needed...... Whats the best way to clean it out of all un-needed files and things?? Manually, or is there a program i can get?? the Computer no longer needs to access the internet...... it only needs to house my Pedigree Program for the rabbits..... I seem to remember having to reboot (not the right word) the whole system, a long time ago..... and the guy that I spoke too had me unplug the thing and hold the power button in and then restart the system from scratch..... anybody got any pointers......??
