Samsung t200 blackout

[lil_rappy]

Hello,
I have a problem with my Samsung T200, which starts to blackout whenever I am playing intense 3D games. In normal desktop mode it's OK, but when I play 3D games for more than 5 minutes it starts to flicker, on and off.
My config, if it helps, is as follows:
AMD X2 5200+ stock, 4GB RAM,Gainward ATI Radeon HD 4850 GS, 2X SATA HD Drives, 1x IDE DVD-Writer, 550W PSU.
What is causing these flickers?
Thank you in advance!
