I have had this weird issue for a month now. I sometimes have trouble trying to initiate the PC to work. It has XP on it. When it boots it loads the progress bar then a power failure occurs. Sometimes it takes a longer time to restart (i.e: I type in my username and password) then it restarts. I noticed that the power supply's fan is not working. So is it the issue of a power supply fault?

As your Power Supply's fan is not working your system may get over heated and trying to shut down to save the system to protect the hardware

  • The power supply fan does not cool the system, it cools the power supply. You shouldn't keep trying to use a device without a fan when a fan was designed into the device. This will always end in bad things happening. Replace your power supply.

I'd change the power supply because the fan is obviously broken and therefore (as Sudantha stated) the pc is overheating and shutting down
