Hi
There are two things I need to know before I can solve the problem.1. what windows is installed on the computer? Is it windows 2000, windows xp, windows vista, windows 7 or something else?
2. do you know if the windows is 64bit version? If you don't know, do you know how much RAM memory does the computer have? less than 4GB? more than 4GB?
To find out which version it is 32 or 64 hold down the windows key and press r, in the run menu that comes up write msinfo32 and click OK
Now on the system information page that opens, on the right of the window find system type
Tell me what it says there if you don't know if the computer has 64bit or 32bit windows installed.
