Thanks. You didn't need to create
a new topic, though.
It looks there are no minidumps on your systems (neither
C:\WINDOWS\MEMORY.DMP or
C:\WINDOWS\Minidump\*.dmp files), so it's not possible to say for sure what's causing these reboots. Could you please follow
this guide and make sure dumps are enabled ("
Kernel Memory Dump" option should be selected). If you can, please provide a screenshot of that window.
In addition, I noticed that the date of you computer is set to 2014. Could you please enter make sure a correct date it set in BIOS and Windows? Even it is not likely a cause of the reboots, it might cause some other unexpected issues. In addition, that might be an indication you CMOS battery is dying (and that could cause the reboots).
