Not able to install drivers

Today I bought a new HDD (Hitachi 1TB), Installed Windows 7. But I'm not able to install display drivers.
Earlier I was using a WD 80GB HDD, everything was working fine, specs are below in signature line.
I am using integrated graphics (HD4250), But now when I installed Win7 in new HDD, HD4250 is not being detected anywhere. dxdiag showing:

When I install drivers v12.6 or from CD that came with MOBO, it doesnot make any effects.

When I boot from my older drive, everything works fine again. What could be happening?

More about install drivers
  1. try installing the same driver version that is on the old drive, if it's not 12.6.

    Have you installed the drivers for the motherboard/chipset yet? if not do that first as that can prevent correct detection of the vid card.
