Hi daffy654,
The O/S is the one I had used to upgrade my original system. I shall try and explain better... When I bought this computer a Dell Dimension 5150 it had Windows XP and I've been adding things to it- an extra 2Mb of memory,a better cd/dvd and then I bought Windows 7 Ultimate and installed that. Then I started having trouble with my internal drive,firstly it was getting to be too small (150Gb.)and then it started 'ticking'!! and getting very hot and noisy,so I bought a new internal hard drive and after several backups? (to my external J: drive) I removed the 'old original drive' and installed the 'new' hard drive. I only have 1 master disc containing Windows 7; so that is the same disc used to upgrade from XP originally. I then used that disc to install Windows7.
Don't know if that makes sense to you-which is probably why I'm writing this!!
Anyway,cheers
