Comments on Wednesday 26 May 2004:
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.) [14:24]

Chris Chambers
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.

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

RavenBlack
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.

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

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

Nameless
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.
