Internet Crashes then Freezes Computer on Launch

Hi there,

I've got a reasonable CPU, only two or so years old - tends to work perfectly (although small fault with an AMD driver that sometimes cuts out for a second or so before rebooting), running windows 7.

Recently been using as normal, then as soon as I do a little too much on the internet (Chrome browser) it will freeze. I can shut the browser, continue with whatever else I'm doing (usually something Office 2013). Then as soon as I go to launch any browser again (Chrome, Mozilla, IE), my whole computer will freeze and require a hard reset.

I've updated my driver for Realtek audio to the latest one, yet hasn't made a difference, any help appreciated
Thanks!
