we'll need a little more info about your DSL, if you can.
for instance, there have recently been sighting of "DSL lite": 1/5 DSL speed at half-price. this may be what you have.
Or, you could live a long way from your CO, slowing your connection, but that's doubtful. DSL guarantees a set speed.
So where are you getting it from? Bellsouth?
Link us to a page that shows your current DSL package, if you can.
It also may be a local problem.
733mhz is realitivly slow, compared to most of todays computers, but loading pages slowly really doesn't have anything to do with hardware.
I suspect a virus, or spyware, or malware: something installed on your computer than is using your DSL connection to send spam, act as a porn dialer, even perform DOS attacks on servers. Try running a virus scan.
http://www.antivirus.com proides a free online scan called housecall. If that doesn't fix it, try flushing your DNS cache.
how to do this:
(i hope you're running windows)
open the start menu
select RUN
type
cmd
press enter
type
ipconfig /flushdns
You've flushed your DNS.
And that's all i can do without some more information.
Make you to watch out for viruses, they really suck.
good luck!
