I just put together my first pc and i am almost positive everything is plugged in right. I turned it on and everything spins and turns on and then after 3 seconds it shuts down. Then 3 seconds later it turns back on, everything spins, and then it turns off. What is causing this? Nothing is showing up on my moniter either.
A big possibility is that something is wrong with the PSU but if not, do make sure you have all of the right power cabled plugged in to everything that needs it. My pc had similar prolems when I didn't have the CPU power cord plugged in as tight as it should have been.
