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?
So based on the other comments, I would check the cooler and anything else that was above the CPU to see if something got too hot and dribbled solder on the CPU. Also is the socket next to that drop clean, or are there other smaller droplets nearby?
Everything on the cooler and motherboard seems to be clean. No droplets around the socket either. We've decided to start the RMA process, because troubleshooting a CPU is a bit out of my wheelhouse and also I'm kinda lazy. Thank you, though!
