Reasons to buy a new PC

Can someone out there give me some help with proposing to the higher ups why a new computer is needed to do my job. I work the order desk and take care of the I.T duties in the company but I have trouble articulating my reasons for the request.besides the fact that my P2 3500 64 MB 10 GB HD is ready to croak:?[]>

Any help would be appreciated.

Thanks!
