Hi, my old PC (Windows 7) is working extreamly slow even after Windows re-installation. Did general optimisation(like switch off effects, defragment, deep antivirus scan, clear cookies and other not necessary data...) still situation does not improve. Realise that there are a lot of quationable processes running and 32bit softwares as windows version is 64bit. Problem is that most of the actions takes few seconds to respond, sometimes opening window freeze. Any suggestion?
