ok now i've had a really big problem relating to win 10 and i got it solved. in short, first i had win 7 32 bit. then win 10 32 bit. Then i made up a mess of my pc and installed three windows 10. Finally i formatted my pc and got win 7 64 bit. Since that it has been slower. I have turned all the visual effects and animations off. Is it due to my RAM, i.e. 3 gb ddr3(1333) or what is the problem? It lags and sometimes an app takes time to open. Its reallly worse than 32 bit win 7 and 10 too.I want to know the reason beacuse if it is RAM then i'm already getting it upgraded to 8gb. Please help.
