quite weird this, I have a maximus formula III P55 motherboard. Just put my new build together. switch it on and it lights up and all fans in my case come on, 5 seconds later it switches its self off, then keeps doing the exact same thing, switching on for 5 seconds then off.
I did manage to luckily get it to boot to windows by pressing the clear CMOS switch on the back of my case. but when ****ting my PC down via windows it would go back to doing the 5 second boot thing.
Any ideas on how I can get it and keep it stable to boot ?
