I updated my Acer Aspire TimelineX 4820TG(not sure of the variant, but i have i3 cpu) to windows 10. I get wrong drivers with auto detection(HD 6550 is a rebrand from HD 5650, so i get HD 5000 series drivers) and I'm unable to download drivers manually.
Just ignore that it says windows 10, because the same problem is still valid.
Oh yes, i forgot to add that all i need is a working manual download page etc. to HD 6550m drivers, and i will newer bother anyone again
Thank you kind stranger who helps me in these dire times
