Today i plugged in my iphone into my computer and the computer shutoff right away. When I looked inside of the computer i had accidentally plugged the usb into the firewire connectors on the mobo. I plugged in a usb drive the other day into both of the ports but nothing happened. Now my computer wont even start back up. When ever i hit the power button nothing will happen. I think that i have this problem ruled down to the motherboard but I was wondering if this has ever happened to anyone else. I am sure that there is not anything wrong with the power supply because i had a spare 600 watt PS that i tried and nothing happened. Also when i plug everything in on the motherboard for power, the light on my mobo comes on. I was just wondering if anyone has any ideas of what i should do. I already sent in for a rma to asus.
