@Pitagora66: Stick with Windows XP (if you can). Microsoft doesn't want to make a Operating System for low resources anymore!! (I truly hate any OS newer than Windows XP because of this, arghhh!!! XP forever!)
Well, back to your problem: How much memory RAM do you have?...
PS: And forget about XP being insecure (like a lot of people say): it's more insecure to use a new system full of hidden backdoors (like, for example, Windows 10 was proven to have), than a well known system protected by a good firewall. I've really lost trust on any new operating system. And forget about any automatic system update, too. This is the sad reality of the computers today. I've been using systems since MS-DOS 6.22, and starting from Windows Vista on, everything was done to EAT you system resources. Windows 7 was good, but not good enough, like XP or Windows 2000 was...
