Socket A is way old... after socket a came 754 and then 939, both if which have been discountinued already, then came AM2 which is still around and the new Phenoms use AM2+AMD has a 'Socket A' type socket, and Asus boards handle 'Socket 775' (LGA775).
Thanks guys!
I followed you suggestions and everything is working properly now!
For people reading this post:
When I applied the Thermal compound/paste, I had to spread it around with my fingers to 1) make sure it was everywhere in the CPU and 2) to make sure I didn't apply too much (I did, so I removed a lot with my fingers).
Tnx again!
