I do not need any data that is stored on this computer but I have no idea how to wipe it and start fresh without paying someone to do it.
do you mean reformat and fresh install?
if you have the cd of operating system, and a complete cd driver of your computer. you can do it for yourself.
just insert the os cd and reboot. press (CRTL-ALT for old computer),f2, f10 or f12 to access the boot option
set cd-drive as first boot.
Regards!!!
