Critical_service_failed
I got this error and bsod a couple days ago when the computer got an automatic update, it happened when booting up after restart. I tried to repair it but ended up doing a system restore. I turned off automatic updates.
then I got it again yesterday after updating java. Had to do a system restore but my c drive was locked so i had to unlock it then do a restore. A couple restore points failed to work but the earliest one did.
Now today i downloaded the new Catalyst 13.11 beta AMD update for BF4. it asked for a reboot as usual, and bam. BSOD. But no critical service failed this time, just a bsod and a loop of repairing c drive and bsod and reboot and so on. Had to resort again to a system restore.

I am pretty scared of turning off my computer, pretty sure it will happen again, even without any update.
ALSO my minidump folder was empty i changed the settings to hopefully start saving the minidump files in the future.

i also tried the command prompt repairmbr
seems to be a boot issue, might not even be related to getting an update. thats the only time i do a full reboot, usually its just hibernating.

if you need any more info let me know im new to this!
