Lola Parra, I'm sorry to hear that you are having issues with your motherboard. Some recommendations I can give you are the following:
- Take the motherboard out of the chassis; put it on a non conducted place. Using minimun configuration (board, processor and power supply only) turn it on.
- It should give a 3 beeps sound since you there is not memory detected.
- Put one memory stick and turn the system on.
Try these steps using the onboard video; if it worked you may try testing the video card.
Finally the mother board is dead, when I tried to turn on without the RAM memory there wasn't any beeps.
It is wear, because the day before just working good.
I already contact with Intel support for the warranty.
Thanks for letting me know.
