I have a computer, and it will not boot. Last night when i rebooted it and just didn't come on again. It powers on, and the cdlight blinks but no output to the monitor, nor does it sound like the hard drive is spinning. Its a fairly new workstation box, http://usa.asus.com/products/mb/socketa/a7n266-vm/overview.htm . i am not sure exactly what to do, any help would be greatly appreciated.
