please what is the latest version of windows 10 of "ati mobility radeon hd 4650" and the official site to download it
there is no Win10 driver for that card as its to old - its not even considered Legacy anymore...
you can try 16.2.1 Beta (https://www.amd.com/en/support/kb/faq/gpu-630 look for link) - but i am not sure that it will work
in Win10 you can only use the "standard Win10 driver" - but only for some office use
its now really time to upgrade your Notebook...
