G-Omaha, you are the Best! Thanks a lot.
ATITool helps. Slow my memory from 280 to 240 and it is OK now.
I have added termal cream to GPU also.
Never seen any game on my laptop before. Now it is very well.
I have Sager NP8790
Bios Revision: V122 1.00.10
KBC/EC firmware rev. 1.00.01
VBIOS Revision: VER008.011.001.068-2004/03/10
PhoenixBIOS 4.0 Release 6.0
What I need to update? Which driver will work well with it?
