Modify the restart behavior for the computer. To do this, follow these steps:
- Right-click My Computer, and then click Properties.
- Click Advanced system settings.
- Click the Advanced tab.
- In the Startup and Recovery section, click Settings.
- Click to clear the Automatically restart check box.

This will let you get the BSOD when your computer reboots/shuts down. To check for errors on previous shut downs you can check the system event log:
- Click the Start button .
- In the Search box, type Event Viewer and hit enter
- In the list of results, double-click Event Viewer.

Let us know if you're getting any errors in the event log at the time that your PC is shutting down. Another possibility is that your system wis restarting after updates are being installed; are you getting any restart notifications from Windows? (a notification will show in a box above the task tray)

If your PC was rebooted as part of a MS update, then Event viewer should give you the reason(s) for the reboot. How often is this happening and how many times has it happened already? Have you updated all of your drivers? You said that this happens while you're away from the PC; do you have any programs running that are causing loads while you're away (maybe a distributed computing program like Folding @ Home or SETI's project)? Is it happening during gaming or when running a particular program?

Have you tried running stress tests? If not, then I'd run Memtest86 in a loop on the RAM for a couple of hours. If that's good, then I'd run simultaneous instances of Prime95 (CPU test) and Furmark (GPU test) for an hour. Use the mobo's utility to monitor temps and voltages while stress testing; log results if the program has that functionality.

Is the machine "shutting down," or is it merely "going to sleep," since you say it picks up right where you left off when you bring it back up? When it shuts down, is the power LED blinking? If so, it may just be asleep or hibernating. Check in your Power settings in Control Panel. Tell it to never sleep and do not allow hibernation and see what happens.
How are your temps?

Ok i just looked deeper in the event viewer and there was 1,364 errors. Some are critical (System shut down) most are just errors (Ntfs) and others are warnings (Ntfs)

Thanks. Check on all those Event Log errors though, in case you've got a failing disk or other problems. If they are things that could be caused by the delayed spin-up of your hard drive, they may have been a consequence of the drive powering down when the system slept.

It could also be a temp problem. Due to the living accomodations i have my computer room gets very warm and my media server/computer turns itself off at night.
