I found my old HP Pavillon desktop disassembled and I wanted to put it back togheter, so I placed everything, connected every fan but when I place the CPU in the right position; even after I "lock" the CPU it moves freely. I looked at the PINS and everything is fine, is it me ? or the am2+ sockets are made to be loose ? I really dunno, The only thing holding the CPU is the heatshield but that cant be it ? Also the computer doesnt start ( fan turns but no bibs and no video ) maybe it is related to the fact the CPU is floating and probably not touching its pins... So; is my mobo supposed to make BIB when no CPU ? helpppp meahhhhhhh!
