We were talking about system backup in order to avoid problems from loosing the operating system.
Yes, while your data are in f:\, your program is installed somewhere like c:\program files. The important point is not the program location, but the other settings you don't see concerning this program, for instance the changes to the registry, or the startup of subservers and associated Ethernet ports!
So, it's interesting to have a backup of all this, able to be rapidly restored while the user date are not disturbed in the f:\ partition.
Alright, that sounds good.
Thank you guys for your suggestions.
BSOD regarding, my guess is that a virus may have infact been causing it - I am no longer getting any BSODs since when I nuked my computer with anti virus applications.
And thank you, everyone, for your time and patience given while we tried to sort out this issue.
