Processor is out of the question, the only package the N3350 is available on is BGA based so it's soldered directly into the motherboard. That laptop doesn't have a dedicated graphics card, uses the iGPU from the processor so you're stuck on that too I'm afraid.

It supports up to 8GB of RAM, but because it's a low end laptop it's possible that RAM is soldered as well. In the same line, with the N3350 being a 6W TDP processor there may not be much of a cooling solution. There ought to be some metal part in contact with the CPU at least, but that's about it. If there was another model of the A315-31 series that shipped with a beefier processor, it would be possible to look for the heatsink part and replace the one you have if it's just a metal piece. It would cool the processor faster, but I don't think it'd improve its performance much if at all.

The hard drive could probably be upgraded to an SSD, there have been reports of other laptops that were incompatible with certain SSDs though so who knows. The overall system would feel snappier, but because of the low power everything else it'd still be a very basic machine.
