Help Extreme Slowness

Hi, I am having huge trouble playing GW, when I go to a new zone the map loads very slowly, even though it says it's at 100% it just sits there, while the computer screams away. Once it's loaded I check the ping and it's at 11,000, while I'm in the game it's not so slow(still below standards). I have tried defraging, it makes no difference. Getting rid of spyware(have Zonealarm) Running Advanced Windows Care and using CCleaner

Specs:

Intel P4 2.5Ghz
512MB RAM
NVIDIA Geforce4 MX 420 64MB
DSL(live in New Zealand so pretty slow, but not that bad, about 800Mbps)

Is it my video card? I can't upgrade to a good card like the 6600GT because of my 200W PSU. Even with a 200W PSU could I still get by with a cheap 5700 or something?

I played prophecies a while back and I don't remember it being so slow, I know Nightfall needs more but when I play Prophecies it's just as bad.

Have you tryed lowering your Graphic settings, if it goes faster then that would be your problem, otherwise im not to sure.

11,000 pings quite bad, im in nz aswell and my ping is average of 300

Not ping, Mbps and, I live in the country, I know it's much better in the city. Yeah I have by selecting auto settings. I have a ping of 450 in game

i'm having the same issue... ive never ever had this issue... i'm thinking just cause fo the holiday events every bot on earth is signing on

Well I had this problem before the wintersday event.

i think anet is just being overloading with to amny issues that they can't fix at once.. its getting annoying though...

This happened to me a while ago and again this past week.
It will load up and hang for a while. I use a little usb device to connect to wireless network. It has a little light that flashes when it is receiving information. I have noticed that when it loads up and pauses for a long time the light doesn't flash, so I suspected that it was my connection.
It may be a firewall, or something like that?

it is your videocard.... you need an upgrade
