Multimedia Video Controller won't install

Got a HP Media Center PC M477UK which I can't seem to get the multimedia video controller installed for. Been on the HP website and downloaded loads of drivers for the model but none have worked, though I have since only installed some .net frameworks.

Can someone point me to the exact driver I need, or at least that will work, if that doesn't work I'll update. Thanks.

 

I could only find the original gfx drivers here ....

and an nvidia gfx update for your machine here ...

When did the gfx stop working properly ? Have you changed the OS or graphics card since you got the machine ?

 

Just reloaded XP thats all. I think I'd installed those before .net, which I read somewhere can cause problems. Just installed again and still not installed. Perhaps I need to un installed and re-install them, how should I do that?
