Unable To Load Webpage Because Server Sent No Data

I did nothing different to my computer. It was online fine and then an hour later when I came back, it wouldn't load any pages. I have a DSL modem and a wireless router that also connects another family member's desktop to the Internet. (As well as our phones via wifi.). The connection is fine on the other PC through a wireless adapter (both are desktops), and on the wifi the phones work perfectly so I know the modem and router aren't the problem. But even though my desktop says it's connected (not wirelessly, it directly connects to the router.), no pages will load. If I use chrome browser it eventually tells me this webpage is not available regardless of which page I try to load, or sometimes it's telling me no data received - unable to load the webpage because the server sent no data. Yet oddly a couple of times after forever it seemed to half load a couple pages. Internet Explorer just keeps trying to load pages forever with blank white page as a result.
