EDIT: We decided not to pursue further diagnosis, because we wouldn’t know what the hell we’re doing anyway, and decided to start the RMA process instead. It might not even be the reason why the PC won’t turn on, but I’m not comfortable with putting that CPU back into his PC again. Once we get a replacement, we’ll see what happens. If it’s still busted, we’ll just take it to a local shop. Thank you everyone for your for your suggestions and insight, they are very much appreciated.

My friend called me to take a look at his PC that wouldn’t turn on. Upon inspecting his CPU, I noticed a silver bump at the bottom. I’ve never seen this. Can anyone tell me what it is?

    It could actually, the Heat spreader is usually bonded to the Chip with some form of Indium Solder, which usually has a melting point of up to 210°C (most compositions are around 120-140°C).

    Solder likes to form a similar ball around traces and components, since the solder does not stick to the silk screen of the PCB.

    And I remember that this is exactly what happened in the Gamer Nexus video, the Indium Solder was melting due to Overheating.
