Windows 7 reboots when idle, no BSOD

Hi all,

I've recently moved all my components to a new case and I'm have a problem with Windows rebooting if I've not touched the computer in around 20 minutes.

There's no BSOD, and no memory dumps take place - it's as if I've pressed the restart button. I've checked the event log, but all that's there is a warning that the computer was not powered down properly. The bug check parameters in this message are all 0x0. Besides that, there are no errors or even warnings that might indicate a cause of the fault.

I've double checked my power settings and at the moment my computer will never sleep or turn the HDDs off. My BIOS is updated to the latest version, as is Windows.

The problem ONLY happens when the computer is idle. I can play a graphically intensive game for hours without any problems.

I'm pretty sure it's not a hardware fault or I'd be seeing these issues at other times besides idling. It seems OK in safe mode too, leading me to think it's possibly a driver issue?

Any help/suggestions/ideas would be much appreciated.
Cheers!

No DMP files included in upload please try this method

We do need the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.

To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.
