I recently built my own Pc and it has been very good but in the last few days when I have been playing the battle feild 1 beta it had been restarting randomly. I had no idea what it was adn thought maybe overheating so I took the side pannel off and a day and a half later nothing had happened but just as I thought I was free and clear it booted off made it to the login screen and did the same again 2 or 3 times then nothing. I tried to turn it on my self flipped the psu switch and kept trying and trying to boot it up but nothing. I sat down and was thinking about what I was going to do and all the sudden it just boots up and all the led's are on and the fans are going but the fans are going way faster than normal. I waited for a minute or so and it just kept doing the same thing so I booted it down and tried to turn it on again and nothing. I sat down and again it boots up but this time it had the little red VGA_LED on and it stayed on then it cycled through the rest of them restarted and then all the lights cycled through and it booted into a windows failed to boot thing. I just selected restart pc and it booted fine. I think it might be my psu ill leave all my specs below and if anyone can help me please do.
