Alright first things first he has an Asus A7N8X Deluxe mobo and AMD 2600+ processor. Alright he says he changed something under his "Advanced Chipset Features" and changed something he thought was his processor speed ot make it higher. He saved his bios and tried to reboot but nothing comes up on his screen. I thought it might tell him "system failed due to overclocking" and then let you go in your bios and restore defaults or fix the bad overclock. He has turned off/on and unpluged/plug back in his comp and no luck nothing ever comes up on his monitor. This really makes me think that he fried his mobo, but he didnt change anything with voltage and the green light on his mobo and his fans and stuff all still come on so idk what to think. any ideas?
