Blue Screen or Restart

I am having my computer reboot or give a BSOD randomly throughout the day, it is a new Optiplex 745.
I have ran a hardware diag and nothing.
I have reinstalled the OS and the same issue.
The possible causes have changed from savrt.sys, ntfs.sys, kmixer.sys, ntkrnlpa.sys.
Any help on this issue would be greatly appreciated.
Thanks

Below is the debug log:
************************************************** *****************************

* Bugcheck Analysis *

************************************************** *****************************

KERNEL_MODE_EXCEPTION_NOT_HANDLED_M (1000008e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: 00000000, The address that the exception occurred at
Arg3: f71ae6c4, Trap Frame
Arg4: 00000000

Turn off or remove Norton software and see if the problem vanishes as well.

If so then install either AVG or Avast free anti-virus.

For all those who read this too, Norton Anti-Virus has a history of messing up peoples computers and usually slows down your computer. I highly recommend AVG.

The Norton did not fix it.
But I did find that the Optiplex 745 has a bios update, and ever since I installed it the blue screens have gone away. (I has been about 3 days now)

Cool! Thanks for the Update and glad things are better!
