How do I reattach a heat sync on a computer processor?

Episode 955 (1:45:16)

Barbara from New Jersey

Barbara was upgrading the RAM on her computer and she discovered her heat sync has loosened on the processor. She knows she needs to reattach it with that heat sync glue that has to be in between it. Leo says to be sure she only uses a drop of that stuff. As for the clip, if it's lose or comes apart, it may need to be soldered back into place. She should be careful to not get solder anywhere else but where she wants it soldered. Solder isn't really strong enough to hold down a clip, though. Since her PC is 8 years old, it may be time to just upgrade.
