well maybe it just isnt recognized right sometimes. if u wanted to take it out then put back in then give it a try, but then u have to mess with ur heatsink and thermal paste which can be a pain. maybe there is a pin thats not touching right, look at the cpu if u take it out and make sure that all of the pins are there. before you do that tho, try resetting the ram actually what bios do u even have?
