Please disable startup programs.
In Windows 7, this needs to be done through msconfig (press Win+R to open Run and type in msconfig). Once in msconfig, disable programs that don't need to be running all the time.
In Windows 8/8.1/10 you can open Task Manager and navigate over to the Startup tab. Once there, disable all programs that don't need to be running all the time.
Disabling a program will not keep it from working, it'll still work when you open it, it just stops it from starting in the background when Windows starts. However, some programs like drivers need to run at startup. Please relay a list of programs listed at startup and we'll decide which can be disabled and which need to be left alone.
