Computer not going at all

If your computer won't turn on at all, the best place to start is to check the power supply to the computer. Is it still plugged in, or has the circuit breaker on your multi-power board popped? After eliminating those issues, the next most likely issue is the power supply unit in your computer. This is the device that converts 240V into 12V, 5V and 3.3V to run all the devices in your machine. If you press the power button and get nothing (no lights, no fans, no noises) then chances are your power supply may be faulty.

Under most circumstances Power Supply Units (PSUs) are easily replaced. If your computer is a conventional, generic style machine it should use a standard ATX power supply which are readily available and easily fitted.

If you've got a brand name machine perhaps with a smaller than usual case (like a slimline case, or Shuttle style machine) then the power supply might be specific to that type of machine and will be more expensive than a generic one. We can usually track the right one down for you.
