Tbh i depends on what kind of person you are. If you really like video games then go ahead but i guess what you are asking is how and that really doesnt answr your question but
1) YOU HAVE TO BE FULLY COMMITTED/ MOTIVATED TO THE GAME
that is the number 1 step.Also try to do a little research on the game and the systems, watch videos on how to take the system apart and back together.
I HAVE FAITH IN YOU!!! YOU CAN DO IT!!! TAKE CHARGE
A power supply unit (or PSU) converts mains AC to low-voltage regulated DCpower for the internal components of acomputer. ... Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.
I don't think so because the old computers may have not been to date as what we have now but check it out and see.
