To be specific, there are 2 main problems.

A site I rely on a lot opens all weird, with wrong orientation, no theme, just weirdly placed hyperlinks with no images (forum. xda-developers. com). I’ve tried it in Chrome, Firefox & IE11. I’ve tried switching the modem on & off, using CCleaner to clear out all the past cookies, cache & browsing history. I also tried opening in incognito mode with all the plugins off. As a last resort I even formatted my laptop. But still it’s the same. On some sites, here and there the images have stopped loading and I get that non loaded broken image icon.

Any ideas on what I can do?

Also I’ve no knowledge whatsoever about networking, I don’t even know how to check my IP address (except visiting whatsmyip.com), so please be descriptive if your solution has something to do with something ’networky'.

Thanks!
