Hi I wanted to see if anyone has come across this issue before. I have a new Asrock z77 Extreme3 motherboard, new 2 X 8GB GSkill Ripjaw DDR3 1600 memory, and a used Intel i5 3570k that I bought from craigslist. To test the setup I got everything onto my bench, attached a known working PSU and powered the setup on. After powering on the cpu fan turns on, I get 4 short beeps and then after about 10 seconds everything turns off again and the the whole cycle repeats. During this time nothing appears on my monitor. I have swapped out the memory with some known working DDR3 1333 memory, tried seating the memory in different configurations consisting of two sticks and one stick, I've reset the cmos. I'm thinking either the motherboard is bad or maybe the cpu. Any help would be appreciated
