Abit error 8.3. Doesn't start

I was playing a game the other day when my computer just lost power.

I tried booting it up again but the fan's would spin and the LED's would come on for less than a second, then go off.

I checked the POST code, it was 8.3. which research led me to believe was a faulty power supply.

I just came back from getting a new power supply, and wouldn't you know it, the same error occurs. When the power is plugged into the motherboard, all the correct lights are on, and the POST code shows 0.1. (which i could find nothing about). The second the power button is pressed it looks like it flashes 8.8. but this is for a millisecond before it shows 8.3. Then it stays at 8.3. till i disconnect the power completely.

My CMOS battery was dead, but i tried switching the jumpers, and got a new battery, and still i cant get it to produce any error other than 8.3.

Anyone have any suggestions or have run into the same or similar situation? As most of you are probably aware, it kills me having my baby dead....
