I have built a system comprising of a Asus P8P67 PRO motherboard, 2500k CPU and a geforce 570 graphics card, when it's up and running it's fine, the problem is when powering on for the first time it powers up, hard drives spin up then after around 5 seconds it turns off, then powers up again by itself and nothing, no display comes on, no beeping, if I hold down the power button to power it off then power it up again it boots first time perfect, I have flashed the bios but still the same, must admit I am a tad baffled.
Any ideas?
