I've recently built my first computer and I'm encountering a problem which doesn't seem too uncommon. My system turns on and off in 5 seconds and then back on continuously. My CPU as well as my case fan spin and I can feel my hard drive moving as well. I've also tried to breadboard my computer with just the CPU, CPU fan, motherboard, integrated graphics or with the actual video card, and my memory in every possible configuration (single in each slot and dual).
I'm not aware of any compatibility issues with my parts and I've made sure all my connections were fine. I'm also not aware of anywhere where the motherboard could be shorted on the case. The CMOS has been reset and I've checked my power source with a multimeter so im not sure if there's anything else I can do.
I also have reason to believe that it could be my motherboard because of my working power source and the unlikely hood that my processor and both sticks of ram would be defective.
Help would be much appreciated! I'd really love someone to diagnose my problem before I buy more parts because I have no idea what I'm doing.
