So I've just ordered a GIGABYTE B360M DS3H and an an i5 7600k with 8 gigs of ram. The CPU is used, from a seller with 100% feedback. Upon connecting everything, properly, and I double checked I did, the system powers on for about 2 seconds, then shuts off. It then power cycles staying on for 2 seconds and staying off for 3 or so. I unplugged every peripheral connector, including ram and the problem persisted. The only thing that seemed to help was unplugging the 2 four pin CPU power connectors on the motherboard, but it would still shut off just stay on longer. Any idea what this could be?
