Welcome to the forum.
There are several ASRock Extreme3 motherboard models, which one do you have?
Is your cpu overclocked? If yes, what is your cpu speed?
We need detailed information about ALL OF THE HARDWARE in your system.
We can offer faster and more detailed suggestions when we know the complete details.
When you list the information in a post, this means that we have to waste time and effort searching for the information.
Some of us are helping in many threads at the same time, sometimes as many as 20 or more.
If you don't post your detailed hardware list in the PC Specs section or in your forum signature, it makes it much more difficult for us to post suggestions that relate to your specific hardware setup. The chance of errors is greatly reduced when we can quickly check your hardware list.
The forum is about sharing information and you make it much easier for viewers if they can easily see your hardware list and if the solution might apply to their setup.
