This happened today, when I woke up I went to turn my PC on then it powered up for split second then turned off then on for about 2 seconds then staying off, I had my iphone 5s charging on it all night so I think that might be it, it was in sleep mode when this happened, so I hit the kill switch on the PSU then turned it back on then I waited for about 30 mins then it turned on then when I put it in sleep mode it then turned on and off like the beginning of the story yeah thats it but, i don't what it was, I don't know if it was me charging my phone or something else can you people help me with this problem.

* This wont fix your problem

Well if this happens only when you are charging your phone , stop charging it
I had some problems with "sleep mode" in the past ( black screens after it ) and i finally turned it off
Since you have an ssd fast booting wont be a problem ( turn off sleep mode , and just turn your pc off when you dont use it)

or better waiting for a more experienced asnwer ;p ( maybe problem its with over-voltage or something)
