my computer is restarting for no reason with no warning and no error screen??

[codyv54321]

I just recently built myself a computer i have had it for about a month i run windows 8 and within a few days of use it started to just automatically restart without warning and with no error screen at first i though it was something i was pressing during the game i was playing but realized its not somedays it dosent even happen and then sometimes it will happen 3 times in an hour my temps are very low so its not overheating. If anyone has any ideas that would be great im not very experienced when it comes to this stuff and this was my first computer i built so i hope its not something i installed correctly and suggestions would be great.

It could be a power supply issue. If under warranty, try RMA-ing it.
