Hi
About a month ago my Hiper 580 PSU started making a high freqency ringing noise all the time (on or off, but still works fine) but now my brothers PC with a Hiper 430 watt PSU has started making the exact same noise, exept his pc wont even turn on anymore!
Both PSUs are approx 18-24 months old (cant remember)
Can anyone suggest anything? Im an electrician and ive checked the voltage ect in the house, all ok. I cant think of anything else???
