So yesterday my computer was running normal and today when i turned it on it started to turn on then it turned off then by itself turned on again and off, several times (each loop lasting about 4seconds+/-) till it turned on (normal) after about 15 of that loop, i was a bit shocked about it and never had this before, so i turned off my computer and turned on and it went normal, i was reading in the internet that it could be MOBO and/or PSU, but i dont have any clue of what is happening can someone shed some light about what happened.

additional info: at the moment im using the computer normally as like nothing ever happened

thanks.

Sorry for bad english, it is not my native language.

Its hard to tell without breadboarding.
A fews days ago it happen to me the exact same thing.
But I didnt wait more than 3 loops of rebooting. I guess I should have waited
I changed the RAM and its all good now.
