Hi,

Exactly which MBP do you have? Apple Menu > About This Mac: year and size.

If your MBP is old enough, it might have removable RAM, in which case you can try reseating it (taking it out and putting it back in to make sure it is seated properly). If that's not the issue, then you'd need to try new RAM.

If the MBP is too new, the RAM is not serviceable and nothing can be done except to replace the entire logic board, which would likely be cost prohibitive.
