Hi,
I have this odd problem. About 5 minutes after a PC has been shutdown, this annoying ‘banging’ sound starts coming from the speakers and a light in the power supply starts flashing.
The problem stops when I turn the power supply off, but I’d like to find a better solution…
There appears to be no problem when the computer is on & in use.
I’ve had a look inside, cleaned out the case, tried to check if any wires are where they shouldn’t be etc, but that hasn’t helped.
Any Ideas?
Thanks a lot.
