fried motherboard?

[jepatbentley]

I own an Asus A7A266 motherboard, my computer appears to start fine, but as soon as it gets past the memory test and the detection of the drives it seems to lock up. If I hit delete to go into setup, it goes into setup and then the keyboard stops working.

Does this definately sound like a fried motherboard?
Could it be something different?
If it is fried does anyone know if how to get an Asus board replaced through the warranty?

Thanks.
