Windows 7 automatically switching to basic (non aero) theme

[AENSLAED]

Hello everyone,

I'm having an issue with the Windows 7 OS themes of my laptop. It's a HP DV4-2116la.
When I open an application or software, no matter how big or small, Windows automatically switches to the basic (non aero) theme every time. This behaviour has never happened to me before.
At the sistem performance options, Aero Peek is enabled. I haven't made any changes to my laptop, it's supposed to run smooth (it is optimized, no addware, no unnecessary background processes), and I don't have any software that stresses the computer.

Anyone who's able to help me out? Thanks!

Thanks @ A Guy for you reply.
unfortunatedly, this settings addressed in the post you recommended are already present in my registry values, and the behavior issues I am having are still happening.

What else could be wrong?

You could try downloading your video drivers, uninstall the current drivers, restart the pc and install the drivers you downloaded.
