All of a sudden my Internet-connection started acting strange: sites wouldn't load properly (didn't load all data, leaving the page to be unfinished, images would be strange-looking), some clients, like Steam, wouldn't find a connection at all times, youtube-videos wouldn't load. I could always be on Skype with my friends and play WoW, though. So clearly I still had connection to the Internet. The speed of my connection is about 53 down and 11 so the speed shouldn't be any problem.
Here's two pictures showing my problem:
Wikipedia: (loaded without proper layout)
Swedish streaming site: (missed the last part of the site and two pictures are yellow-ish)
I just now finished a reinstallation of Windows 7 (I deleted ALL data that previously was on the hard drive) and still I've got the same problem.
To make sure it wasn't my WLAN reciever that was broken I threaded via both my mac and my samsung, but both with the same result. I've also made sure it isn't my router by using my phones 3G.
As I said in the title, I'm only experiencing this problem on one of my computers, so I'm beginning to think It's some problem with my hardware.
Do any off you guys have any idea what might cause this problem? I'm starting to get sooo irritated. Thank you!
Edit: for the record I have tried Explorer, Firefox and Chrome.
