Hi guys, Wondering what I should do. I bought a new motherboard, RAM, Geforce TI 560 and an i7 2600k CPU, installed it all and when I turn it on it'll try to boot but just restarts, within usually 10 seconds. I've checked the PSU (it's a Seasonic 550W) with a PSU tester and it's fine, it's currently powering my old hardware right now (moved my old Core 2 Duo stuff back in). I can't test the CPU with another motherboard and same thing with the motherboard, can't test it with another CPU. I've tried booting it up with just the motherboard, CPU, one stick of RAM (tried alternating them both) and my old video card outside of the case, yet it still does the same thing. What is the most likely cause? How can I RMA something when I'm not sure which part is failing?
