Seems every so often my pc will get stuck in a reboot cycle, i'll see the win 8.1 logo for an instant then it'll reset and start over. This morning though it was a little different, the pc got to the logo and shut down with no attempt at a reboot. I pressed the power button to boot it again and lo and behold into a reboot cycle.

This seems to occur pretty frequently and ive no idea what causes it, ive seen a lot of people talking about reboot cycles with automatic repair being an issue. Seems the only way i can get this to work is to power off, unplug the psu for a few seconds, reboot, and hit the reset button when i see automatic repair beneath the windows logo and usually it'll start fine after that. Doesn't always work though, just last week i had to format the pc because it point blank refused to go past this nomatter what i did. :(
 
It will do this when completing the installation of certain updates, but they shouldn't be frequent (patch Tuesday once a month, plus the odd out-of-cycle update).
 
Its a random event though, no updates were installed when i shut the pc down, rebooted it, got to the windows logo, pc shuts down suddenly, then goes into the infinite reboot cycle.
 
Overclock is stable and latest bios is installed, even on default cpu settings this can happen. It went through the same routine again this morning, shut itself down requiring me to hit the power button again, into a reboot cycle which was only fixed when i turned the pc off then let it get into automatic repair, which it couldn't do before as it just continued to reboot cycle.
 
Have you turned off automatic restart on BSOD so you can see if you are getting an error?
Sounds like its restarting because this option is on.

Check event viewer and get a memory dump analyzed.
