I'm not sure what you mean by "When you're monitor goes blank, does your system go to sleep?" but I can tell you that if I am in the middle of typing something and the screen goes blank, if I keep typing the words I type are in the document when I bring the monitor back up. So I guess the answer is no.
When the monitor was on the other system, the PC was turned off each night, after about 16 hours of being on. The monitor was off when the PC was off.
Do you think it could be the keyboard "Sleep" button playing up that is causing the problem?
