Problems loading most internet sites on all browsers

[DRYJESUS]

Hey guys,
For a few weeks I have had problems loading SOME internet sites. They either don't load, or it takes ages (10-20 minutes) and even after that they don't load correctly. This is the same for IE, Firefox and Safari. Sometimes Firefox can load more websites that the others, but it's usually random. Sometimes Facebook works perfectly fine, but sometimes it won't load at all, or will show a really bad... sort of... text only version.
I've tried using Hijackthis and deleted some suspicious looking stuff, but it's still the same. My sisters computer which is connected to the same router isn't having problems.
I've tried booting in Safe Mode with Networking, and the problem still consists.

All of my other programs seem to work fine though, such as MSN, and some video streaming programs that I have. Any help would be great.

This is actually for my friend, so I don't know the system specs. I do know that she has Windows XP though. Honestly, I don't know if updating the network card would do anything. It's been working for years, until last week. This is a really old machine, I'm not even sure if there are updates being made for any of the components anymore. Which anti-virus, etc. do you recommend for me to scan with?

I would actually be interested in how much RAM the system has, I personally noticed that after a very recent patch, XP has been hogging a lot more RAM than it used to. It proved to be a big issue using Firefox/Chrome/IE8, as the pages wouldn't load until after the page file was written to.

try a live cd with ubuntu or pcos or something. same issue? its hardware or modem/line related or something :)

have you check the processes and services under task manager when you try loading websites?
Are there any suspicious tasks?
Try killing them and see if it works.

Ninja'd!!!!!

I second the suggestion that you should probably be looking for a DNS issue.

Aside from that... removing and re-installing the network card should re-install the stack which might solve the issue as well.
