this unit was working. i took it out of the case to clean off the dust. when i put it back in, i hooked up the pwrbt, reset, speaker, and hdd jumpers backwards on the pin header. i did apply power, nothing happened. i realized i hooked them up wrong and swapped them. now when i power up, all i get is "Over ride" on the moniter. dvd+r powers up, and hdd sounds like it is working. what is my problem? did i kill the processor and or motherboard? please help!
