Unexpected Shut Down when System is Idle

Hi All

My computer (Specs Below) will shut down after i leave it for about 5 - 10 minutes of idle(ness).

This usually happens during my drive to work, so i am not too sure what causes it & how it shuts down, however there are no logs in the event viewer, aside from the odd "Application Experience is now in a stopped state" info log.


Typically, when this happens, by BIOS Boot priorities are also reset, forcing me to go into the BIOS, set the raid (for my OS) to HDD BBS #1, then set the boot order: 1.Raid0 2.BD-RW



All of the power swaving options on my system are turned off, my system is configured to ALWAYS run as i use FTP & VMs all the time on that machine for work & uni


This type of problem has happened before, in the end my Raid 0 got corrupted before i could figure it out & i had to re install the OS, which stopped the problem.



The only change to the system that has been made recently was 2 days ago, i had to update my BIOS as i was having RAM issues & the BIOS update contained a fix.

that also required me to reseat my ram a few times (fault finding), however i didnt get any errors in Memtest86 when i was finished poking around.


If anyone has any idea why this is happening, please let me know. This is beginning to bug me...

Thanks!!!
