[[HELP] PC restarted while gaming]

This could be a whole lot of things. I have a few questions:

 

1. What game were you playing (some pc games are just prone to crashing)

2. What exactly happened when the pc crashed? Did you see the blue screen? Did the pc just instantly restart?

3. Did you get any kind of warnings before it crashed? Did the PC make any strange sounds? 

Thanks for the reply!

 

1. Only when playing Dota2

2. It just auto restarting when i was playing (random time)

3. I got no notification it's all normal then just restart by itself, the sound from PC maybe just fans that relaunched (sound like turning on pc)
