I think I've experienced this before I reformatted the machine and after (I'm pretty sure I reformatted, yeah I did)

The issue is that sites will take forever to load on the machine, or sometimes they just wont load.
This has recently became a problem since even though this is just a server computer now and I don't browse on it, I am trying to make some php scripts that would fetch a page's source, and it can't even fetch a page that has like 25 small lines of source, it's an RSS feed I'm trying to fetch with php, but that's aside from the point, I guess even php chokes up trying to recieve a page, but I can get the header info instantly.

A couple of interesting things are that everything not on port 80 seems to function just fine, and it's hosting a game server and a web server (so outbound works) and all other app ports seem to work just fine, they don't choke up like web browsing does, it also seems to be receiving the header to the site, because it will set the window title name and then just choke after that (sorry for repetitiveness I've been jumping around in this document(explained in the php part)).

I've tried researching this but it seems pretty rare, and anything I find hasn't been resolved any ways, so now I'm going to try and take a bat at by making my own post.

Back when it was my main machine there was a point at which I thought IE8 just sucked a lot because I would at times have to open up literally like 4-12 tabs of the same link before it would actually load on one of the pages (middling clicking links became my friend), but now days I have IE, FF and Chromium on the machine and they all will choke up on random pages, sometimes pages load, some/certain pages seem to load more easier than others, but as for them choking up, I have no idea what's going on.

What do you think could be the issue, I know it's not the modem/router, because I have other machines on the network that work fine. I did hate intel's drivers downloads but I just found my Main disk and installed the ol' drivers from it last night and still the issue is there, so I guess I had the right drivers all along too.

Could this be a dns issue? I'm pretty sure in the past I've tried connecting to the IP address of sites, and still it chokes up on the content of the page.

Any input, thoughts, ideas are welcomed, I'll try anything to get this to work, I'd even give remote access if you wanted to diagnose that far, I just pray that I can get this to work.

Maybe faulty cable/onboard card? But why just port 80.
and if it were a virus how would a clean install have this issue?
I know I have old files so maybe something that's really stealthy got loaded in to the system but by opening / seraching on files on the system.
It may have been a slim lined XP but I think it's a normal build of it.
