windows - I have to refresh browser all the time to view a webpage, and sometimes only text appears instead

I have to refresh my browser all the time.

Browser doesn't matter, this happens in all browsers.

The problem is when I enter a URL, sometimes the page loads fine, but most times the page won't load (keeps loading without anything happening), or it loads but only text is visible and not the pictures, OR the browser displays some strange text like "host: blabla, connection: keep-alive etc etc" (text which isn't on the webpage at all).

I have no clue what it could be... It has been bugging me for months now.

I have a network cable with a DSL connection, and I have all drivers setup from the manufacturers website for all computer components.

I run Windows XP.

I am suspecting my network card (ethernet card). It is Broadcom NetXtreme GBabit Ethernet.

Is anybody having the same issue?

If you need more input let me know...
