Just buildt a new system.

Turn on power and black screen. No beeps.

All fans are working. DVD can eject. So PSU seems fine.

As soon as power is connected the green Boot_device_led on mobo has a constant green light.

As soon as I start up the PC, the red CPU_led has a constant red light.

I do not know if the constant green light from Boot_device_led indicates anything? (if it is supposed to always be on).

I do understand that the constant red light from CPU led is probably not a good sign.

Anyone had similar experiences with this Motherboard?


Components are:

- P7P55 D Motherboard

- i7-860 CPU

- Cooler Master Hyper 212 Plus CPU Cooler

- HX850 PSU

- 2 x Corsair XMS3 DDR3 1600MHz 4GB CL8

- Gainward GTS 250 Videocard

Any kind of long beeps?

I'd say reseat the video card (check power connections) and reset the memory sticks.

The READ before posting about boot problems! sticky at the top of the forum was created to troubleshoot this exact type of problem. You should start off by performing EVERY step in the checklist. My guess is that #2 will get you going.
