It's modded like the previous one. what you first can try to do is clear the cmos, second try to boot to see if it helps. If that doesn't work try holding down "TAB" key while trying to startup.
Striker Extreme Bios 1504 None of those help, thanks Fzeven, tomorow i will purchase a P5K premium /WIFI AP to replace this one, and give it back to asus, because the person that as sold me this model doesn´t sell computer parts anymore. Bad luck of mine (we all know that this can happen, so don´t worry Fzeven, i will ask you if you can mod for the purchase of tomorow the P5K premium /WIFI AP last bios). Continue the great work.
