Hey guys. Finaly got my cooler for my CPU! phew! Anyway...Everything is up and running and now I inserted the XP disk into the DVD-ROM drive and booted with disk. The black screen appears saying press any key to begin setup! I press any key and it begins to do stuff...detecting stuff and things like that....but since the HDD is full..I need to reformat it...how on earth do I go about doing this????? Thanks.
