Hi there ,the motherboard in my dimension E520 is broken and i came accross a 0WG864
I have searched around the net and asked a few people and never get a concrete answer
Plz help me as im a complete noob !

The only difference i can see is the heat sink circled in the picture is not there in the 0WG864 board

Thx in advance for your time and patience .
