First time build, test came out negative. I removed HS and up came the amd cpu attached to it. Read here how others recommended the other party to use a hair dryer, or rubbing alcohol to remove the old paste. Youtube AMD Pro says never use any liguid to separate the cpu from the HS. Where do these members get such info. I got mine off very easily, by doing a little twist. With a bandage gauze i wiped off the remaining paste..checked the pins and they look perfect. This build is like looking for a needle in a haystack to find out why only the standby led on the MB comes on...and could someone tell the purpose of that cpu lock lever?
