Problem
The minecraft launcher won't start, and you get the following type of error - found in a file called hs_err_pid

#   # A fatal error has been detected by the Java Runtime Environment: #   #  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000006abaf5bf, pid=9176, tid=4868 #   # JRE version: 7.0_05-b05 # Java VM: Java HotSpot(TM) 64-Bit Server VM (23.1-b03 mixed mode windows-amd64 compressed oops) # Problematic frame: # C [aticfx64.dll+0x2f5bf]  GetKtProcAddress+0xfaf #   # Failed to write core dump.

Cause
The "Problematic frame" is caused from the graphics card drivers being out of date.

Solution
Update the graphics card drivers.


 * nVidia drivers - http://www.nvidia.com/Download/index.aspx
 * AMD drivers - http://support.amd.com/us/gpudownload/Pages/index.aspx
 * Intel driver - http://www.nvidia.com/Download/index.aspx

Sometimes a graphics card is too old for its drivers to be easily found at the above sites. You can find out the name of your graphics card by running dxdiag and going to the Display tab. Once you know the name of your graphics card and its current version, you can then perform a web search for updated display drivers for it, by using a search parameter such as:

"GeForce 9600 GT" driver update

and looking for results that have a more recent version of drivers for you to download and install.
