Hi guys, I tried to install my new I7 700k into my pc about 20 minutes ago and I did everything accordingly to plan (I think). Inserted the CPU, applied thermal paste, screwed the cooler in and then fired it up. The PC fan started turning and everything was going to plan or so I thought. The monitor didn't turn on as usual with the GIGABYTE ULTRA DURABLE screen and within a few seconds the PC just turns itself off. The monitor doesn't turn on as usual. I tried it again and the same happened, comes on for a few seconds and then goes back off. Help please ?
