HP pavilion g6

Hi I have a old 2011 HP Pavilion g6-1331sa notebook that runs very slow with Win 10 20H2. CPU being AMD a8-3520m 4 core 1.6-2.5ghz clock frequency, 35V, socket FS1, dia size 228mm code name Liano released 20 Dec 2012. Want to look for a upgrade CPU that is compatible. Problem is finding one...

Recently, after the new chrome update, sometimes when I close a tab, chrome stops responding. No matter how long I wait, it wont start responding again, and I have to close it and re-open it. Any solutions?
