All apps closing down overnight when pc is in sleep.

Do you have Hibernation enabled?

you may want to check the following setting in Power Options. Navigate to Power Options in Control Panel and click your power plan (usually Balanced or Power Saver). Click the Advanced power options link and look for this setting:

If the setting for On Battery is similar to mine here, change it to 0 (never). That should correct it for you.

We should not be advising users to disable Hibernate, which is perfected in Win7 and allows work saved on the desktop to be written to HD so the PC can shut down, yet starts up much faster with the work left where it was.

I set all of my installs to 20 minutes display timeout, 30 minutes sleep, then an hour or so Hibernate. This allows the PC to be waiting if you're likely to come back to resume quickly, but still saves your work and shuts down if you don't come back for a day or a week.

Hybrid sleep writes your work to both RAM and HDD so if there's a power failure it wont be lost in RAM alone.

There is no upside to advising not to use the functions, any more than one would advise not to use a heater in a car to save gas. These are modern features that make the PC work better for you and help preserve your work.

If Sleep or Hibernate aren't working correctly then update your Display driver or try another one, then try these solutinos to Sleep Mode Problems - Vista Forums.

If problems persist check the System Resources, establish a Clean Boot, read the Performance log for clues at time of problem as given in Troubleshooting Steps for Windows 7.

As a last resort you can use the tool the Pro's use to determine with certainty the cause by Gathering a Startup, Shutdown, Sleep, Hibernate, or Reboot Trace - Windows 7 Forums

Just to add, I have seen this kind of behavior with Windows Updates. If you have them set to automatic, the system will prompt you about rebooting upon completion of an update and give a selection of times for a reminder if you'd rather postpone. I have found that when I've put the computer to sleep with a reboot pending, often the reboot will eventually take place once the postponement time has elapsed (either user specified or default) despite the computer being asleep. I've observed this happen under Vista, so I assume it also likely happens under W7. It could explain why you see this happen if it's not consistently occurring every night. Windows receives frequent updates, many of which encourage rebooting.
