Brand new machine that was working fine then randomly it changed the theme when I booted into a sort of "basic" theme (white task bar, no see through windows etc)

I've done and attempted many fixes and I still don't understand why it doesn't work. I've tried these two solutions:

"How to enable Windows 7 Aero Theme"

and

"Windows 7 Aero Themes Greyed out"

These solutions included registy changes, stopping/starting services, and force starting the aero theme. The closest I got seems to be when I went into:

Control panel (category view) > Find and fix problems (System and Security) > Display Aero Desktop Effects

I follow through the wizard and let it do its thing and then I get an error window that pops up: Personalization - "This theme can't be applied to the desktop. Try clicking a diffrent theme."

That's what I get from the wizard. What can I do? My drivers are all up to date, there are no viruses on the computer, directx is installed and updated, and the registry is all correct.

EDIT: When I boot the computer, I get a notification stating that windows failed to communicate with the windows desktop services.
