Take out your Mobo and bake it at 375 for 7.5 minutes. That will reball your v-chip. Works every time while saving $. Update: Make foil posts. Elevate the mobo above cookie sheet. Make sure you pre-heat to 375. Bake for 7.5 mins. Remove ALL plastic bits, the two guides on the back of mobo and the sticky cover on the little chips near the processor. Bake it. Let it return to room temp. Before reinstalling your mobo, clean the huge amount of dust out of the heat sink/fan area. This is usually where the problem begins and MUST be cleaned.
