I installed WIndows 7 fresh on my laptop, and now it boots in Fixed mode (Switchable graphics as set in BIOS)

But on booting, whenever dGPU (AMD 6770M) is selected, I get screen tearing.

And this screen tearing continues right from the time I boot.

What to do? Please help. Why can't I run fixed mode properly on my laptop.
