System problem..

[needsumhelplol]

Hi..

My computer is restarting by itself.. Under System ''Automatically Restart on System Failure'' is unchecked and i checked for a log but it's not creating one in %SystemRoot%\MEMORY.DMP

CPU was at like 35c and 'System' at 32c.. GPU 40c..

Is there any reason someone can think of why it would be restarting like this.. it would appear to not be producing a BSOD and not overheating.. so i'm kind of out of ideas...

Thanks.

(sorry if this is in the wrong section)

Mhm thanks... i'm getting those temps from software that runs up until my system restarts not the bios that's why i'm sure it's not overheating... If i meant it was constantly restarting, i'd say that instead

Anyway i seem to have fixed it... only things i changed was my CPU fan from PWM to DC and i turned ACC on in the bios... i dunno which one is the more likely fix though
