First place to look could be your PSU.

Sudden shutdowns can be related too:

PSU: Faulty - Not outputting enough wattage to supply the system.
CPU: Heat - could be overheating - the shutdown happening in games ?
O/C: You might need a bit more voltage to get it stable if you have it overclocked.
M/b: Power Regulators might be overheating causing immediate shutdown. Check the temps of your northbridge/mosfets

Just a few idea's to get you started.

how do i check
M/b: Power Regulators might be overheating causing immediate shutdown. Check the temps of your northbridge/mosfets

it shut down either in game or just after coming out of game
I dont not have the system over clocked.
any thanks

What is your cpu temp under load? 45c is a little high if thats at idle. and iirc the A8n32 has a default shutdown temp of 60c for cpu which could well be the case if your idling at 45.

id say about 45-50 but it also shuts down on desktop
