Ubuntu randomly shuts down in about five minutes of playing minecraft

[TheUnseen_]

Any one have any idea on way it does it I know my computer can handle it and it's not ever heating and in the five minutes I do get to play it runs better on ubuntu then it does on windows

my processor is a Intel® Core™2 Duo CPU P8400 @ 2.26GHz × 2
graphics GeForce 9800M GTS/PCIe/SSE2
OS type 32-bit witch is weird this is a 64-bit computer
ubuntu 13.04 and im running the gui of kubuntu

Hi can you please test your system with prime95/mprime and see if same behavior occurs?

download the linux 32 or 64 bit version. ( i use 64bit)
extract files then run mprime file.

tar -xzf p95v285.linux64.tar.gz 
./mprime
