Every time i go to render a video, i begin to hear a loud beeping come out of my computer. I think its the warning beep on one of the parts. I'm not too experienced with pc parts so I dont know what that is. This beeping occasionally comes on when I game too, however, when i render, its more prevalent. Eventually my PC just blue screens with a warning message. This didn't always happen so I'm not sure what's going on. I hadnt tried to render a video in like half a year due to the fact that this issue was happening back then. So when I tried doing it today, it did it again. Please help. Thanks so much!

 

Is there a error code in that blue screen? And what is the warning message?
