Hello,

If I were to desolder a SMD CPU or GPU and solder in a new one that is faster, would the computer still be able to run (assuming everything is soldered correctly)?

Thank You

Depends on what your talking about.
For example with a Pci-e based graphics card. if you tried to replace the existing GPU with a higher rated one NO.
Because the BGA pin array is different, and the circuits of the board are designed to run with the model of GPU or its revision.

With Cpu`s If in the same model range and class yes.
But its dependent on the bios or firmware of the motherboard.
Soldered on Cpu`s or Bga array chips are often paired with the circuit design of the board.
Add to the fact that the board will have a set power rating, by putting a faster GPU or CPU in it will require more power.
And likely not work due to Bga as its a fixed bit of hardware.
