Environment : Win-Vista 64 BIT
Graphics Processor / Vendor NVIDIA GeForce 8400M GS Video Memory 256 MB Total Available Graphics Memory 1535 MB
What happens is, i can use the laptop in "basic theme" ONLY, the moment i enable any aero theme, the screen tears up, discoloration appears & then laptop freezes. Sometimes its reboot itself with Blue Screen shows up the gfx card error.
Any way around, highly appreciated.
