ok yesterday i was playing around with a steering wheel and i think i crossed some pwr wires. i think i shorted out something on the mother board. the usbs would not work so i restarted it. no boot. wouldnt do anything after the post screen just the blinking cursor in the top left corner. so i try to and unplug hdd, nothing works. i finally just wiped all the hdds and reinstall win7. working fine. installed updates and video drivers and restarted same thing. no boot. can boot from dvd but thats just the install dics. try to repair but it doesnt see windows. i dont know what to do.
That sounds really bizzare... Having short circuited the motherboard, you could have caused irreversible damage to any of the components (including the BIOS chip), therefore exhibiting this strange problem. I would try to flash the BIOS of the mobo. If that doesn't help I woule probably look for another motherboard, as you can't really trust this one any more.
