Your probably going to have to buy a new one.
You pretty much are going to have to purchase a new motherboard. When you fry, it's fried.
You can just try resetting the BIOS. Just unplug the system and pull the CMOS Battery. But other than that, You might have to get a new MoBo.
That fricken sucks.
I want to try resetting the bios but I dunno how to access it with this hardware. Is there a reset button on the motherboard? or shud i try taking out the battery and putting it back in again? ahh jeez. It's not even my computer
If it's fried, well then it's fried, resetting the cmos won't do anything. But if you really want to, there should be a cmos jumper somewhere on the mobo, you have to set that to reset for a bit, that should reset it. Or you can try taking the better out of the motherboard and leaving the computer unplugged for a bit.
