| Computer hardware conundrum - what would cause a power supply unit to make annoying screeching noises? What would cause this to occur in a new power supply, different brand, that has recently replaced one that was doing the same thing? What would match both these criteria and would also consistently be cured for a few hours by removing the computer's case and punching the offending PSU? (Removing the case not being a factor except in that it's necessary in order to be able to punch the PSU.)

| Is the second power supply brand new, or is it just new to the system? Usually, screechy noises are a sign that a ball bearing is out of alignment in the PSU fan. |

| What he said. Can the noise be resolved by pressing against the center of the PSU fan? |

| It was brand new, and no, pressing against any part of the PSU does nothing, only punching it seems to make it shut up. |
| James |
| Push hard enough to make the fan stop spinning. |

| Since the old one was making a screechy noise, maybe it's something attached to the PCU, or slightly touching it? Just an idea..... |

| It's a trick question, all signs point to computer gremlins. |

| Computer gremlins? Rubbish. Did you ever see The Brave Little Toaster To The Rescue? If so afflicted, do you remember the little virus-y demon-looking things? Yeah. It's them. |
