so my brothers psu went out and we sent it in for another one, it's an ocz 600w psu. i just now got back the new one and popped it in. now i've run into some problems, about 30 seconds after i boot it up it shutsdown. i've went through the everything making sure all the connections are tight and what not. i'm pretty sure it has to be the psu because the case has just been sitting in his room. soooo i'm thinking i'll probably have to send it in again or something, idk but for now i'm going to checking everything over 1 last time and see if it's just somthing i'm missing.
edit: also it boots up fine, post and everything...
