Dont know if this is the right section but i really need help. I have had computer troubles for almost a month now and i really just wanna finish my PC. I just got my new motherboard which i had to replcace the old one with. I plugged everything in and hurray it works. I get to my bios screen and everything works. Then after around a minute it just shuts off. I try it again and the same thing happens. My stats are in my info except for now i have a gigabyte motherboard. So what do you think could be wrong?
