Not sure if this has been posted before since it is kinda wierd. Now I 'transplanted' my pc from a prodigy m to a haf x because I could and it boots up and shows the mobo screen, I can go into the bios and it won't turn off, but if I dont go into the bios it turns off after showing the mobo screen for around 8 seconds. i think it's most likely a software issue as everything is plugged in and working.
