I recently bought a Asus P4P800SE Motherboard. I installed it correctly and when i started it up. I have to press a key on the keyboard to wake it up then it will start booting but, all that happens is 3-4 rapid beeps then all I see is a blinking underscore. I read the manual and it said you have to wait 30 seconds because of the first time booting it up, the mobo has to collect all the data for a first start-up. It has been much more then 30 seconds and I have tried over 5 times. It is too late to call Tech Support. The manual tells me if something doesn't happen in 30 seconds to check jumpers.
Jumpers are all on default.

CAN SOMEONE PLEASE HELP?!
