So let me start of saying that this is a prebuilt IBUYPOWER computer D: (Never again)

I received my new GPU today (gtx 980 ti hybrid) and after installing it, the system restarts after every 15 seconds or so and wont stay on. After talking to useless tech support I tried removing the graphics card and turning on the system without it, but same problem occurs almost no difference. The tech support told me that I may have shorted the motherboard or a PSU problem. Any help or input would be appreciated!
