Hello, have you looked at the status of the motherboard using the leds on the top right. It might help you to know where your problem comes from.

Hi,

I'm not sure that a comment section of a sales site is the best place to get support. I think you'll get better answers on the hardware.co.uk forum, commencamarche or tom's hardware.

You should also describe the problem better: which processor? which cooler? did you use the thermal paste? which RAM? did you respect the slots? which hd/ssd? which graphics card? did you use the right PCI Express slot? which monitor? how is your monitor connected (DVI, HDMI, Display Port)? did you try with the graphics card integrated in the processor ? do the fans turn ? are there any beeps at startup ? what do the motherboard lights indicate ? which power supply ? is the power supply correctly connected (main + auxiliary connector) ?

Look at page 1-12 (1.1.8 Motherboard lights) of your motherboard manual about the LEDs. Also see page 2-18 (2.3 Getting started for the first time) about the beeps: https://dlcdnets.asus.com/pub...

I had found the problem and now they all work. Thank you very much!

Very good, thank you very much!
