Learn to troubleshoot power supply problems - TechRepublic

QUOTE A BIT: (there is info on how to trouble shoot PSU in that link)

The symptoms
Just about any intermittent problem can be caused by a faulty power supply. I normally look there first when the symptoms are a little weird. Common power-related symptoms include:

  • Any power-on or system startup failures or lockups
  • Spontaneous rebooting or intermittent lockups during normal operation
  • Intermittent parity check or other memory-type errors
  • HDD and fan simultaneously failing to spin (no +12V)
  • Overheating due to fan failure
  • Small brownouts that cause the system to restart
  • Electric shocks that are felt when the case is touched

There are also some obvious clues that should lead you to suspect a faulty power supply. These include:

  • A system that is completely dead (nothing happens when the system is turned on)
  • Smoke
  • Circuit breakers popping when the PC is turned on
