What are the symptoms of system power problems?
Symptoms of Power Supply Problems
- The power light is off and/or the device won’t turn on.
- The power supply fan does not turn when the computer is powered on.
- The computer sounds a continuous beep.
- When the computer powers on, it does not beep at all.
- When the computer powers on, it sounds repeating short beeps.
How do I test my computer parts with a multimeter?
Unplug the computer from AC power and allow several minutes for any excess charge to drain. Set the multimeter to the lowest Ohm setting (around 200) and touch the leads of the probes together to zero the meter. Touch the two leads to the bare metal of the computer’s chassis; the zero reading should be the same.
