This has happened around 3 times in the past week, and each time it has been while i was on facebook (no idea if that is relevant). Has never happened whilst gaming or anything else.

If anyone has any idea whats causing it, please please help me. Thanks

Follow Blue Screen of Death (BSOD) Posting Instructions, let the tool run until it has completely finished and then upload the new logs.

Please fill out your System Specs

   Information

Your System Specs will help us to help you, and doing it in this manner will make them available to all helpers in every post and keep us from hunting for them. We ask that you fill them out in as much detail as possible including Desktop or Laptop, Model number if it is an OEM computer and all components with the Manufacturer and Model number if possible.

If you will go to your last post and click the 'System Specs' in the bottom left of the post, you will find a link to update your system specs. Please fill those out in as much detail as possible. If you would like to know what we would like, you can click 'My System Specs' at the bottom left of this post to see mine. If you do not know what your components are, this will help you accomplish this task. System Info - See Your System Specs

Gibster, please post Blue Screen of Death (BSOD) Posting Instructions so we will have something to look at.

Also, be aware that you have unlocked 2 extra cores on your CPU. The cores were locked because they were not able to perform up to standards. That's why they were not used, but you have decided to use them. So, in all honesty, that could very well be at least part of the problem. Also, if you are overclocking anything, please set everything back to default settings.

Gibster, all of your dump files point to your Graphics driver.

I recommend you do a clean install of the drivers. Download them from AMD.com and clean leftover drivers using this method Drivers - Clean Left over Files after Uninstalling
Try that and let us know if that helps.

Let us know how it works out for you.
