[MTUSUPPORT]

Flipper,
When you change the DirectX Hardware acceleration it should always hold this when the computer is rebooted.

I am not sure why your computer is not holding this setting. This is part of Windows, and there is no other control over this setting, that I am aware of.

You may also try going to the Laptop Manufacturers website, and get the very latest drivers for your motherboard (Chipset Drivers) and also the latest video drivers for that Laptop.

Have you run all of the Windows Updates also? If not then I would recommend doing this also.
