Windows 7 system, working with the machine, don't want to reinstall,
Normally, after the system startup, will load the system variables, and then load the user variables, general variables will be covered by a user variable with the same, but the path of this variable would be the result of superposition (append),

Problem now is that at the time of entering the system, everything is normal, but after all the application load when the system, part of the system variables to disappear, the path only user variables, this variable is similar to the user variables to ignore system reload time,
So-called normal, it is when I was in early into the system, open a command line window, into the SET command to check the system variables, everything is normal, over a period of time, open another command line window, partial variable disappears,

Machine has been open, find the problem until today to restart, several software because there is no path, all kinds of error,

What tools can help to find problem, please?
