sony laptop motherboard issues

Hi this is my first time on these forums. I got an Sony VGN-AR71J laptop about a month ago and its been great, but the other morning it would not turn on. I had used it the day before and it worked fine. When I press the power button, the power light comes on, the fan comes on at full speed , but the sony bios screen never comes up. The system did this once or twice before, but it always started on the second attempt. Now it won't start no matter how many times I try.

I assume this is a motherboard issue. Is there anything I could be overlooking with this particular model? I submitted an online support case to HP, but haven't gotten a response back yet. I'm going to call support tomorrow if I still haven't heard back, I just wanted to know if there was anything else I could try before I have send it back.
Thanks for your help sony laptop
