I just recently purchased the same CPU/ MOBO combo. It is now working fantasticly, but upon first installation, things did not go well. Like you, I dont think of myself as computer illiterate as I too have built several systems for myself and others. Although I dont know for fact, your experience is drawing me to this thought. The heatsink and fan are very difficult to install on this particular board. And although it appears that the heatsink is sitting flush on the chip, it may not be. I dont know if the rubber spacers on the chip causes this. As you stated, the thermal gel was uneven which indicates that the chip could have been on crooked, therefore increasing the chance of frying your chip. So, I was suggest taking it back regardless if you can. LOTS of places have no issues with chip replacement, but some places wont take em back. The place you bought it may be able to test both the board and the chip. Good luck. Hope this helps.
