[QUOTE="chscag, post: 1726393, member: 46727"] Hopefully, your Power Supply has settled down and will remain quiet. Many times the buzzing can actually be caused by "dirty" power coming into your Mac. If the buzzing returns, you might try attaching your iMac to a filtered UPS (uninterrupted power supply). You should be able to buy one in Denmark from a store that sells electronic components. Otherwise, you can try ordering a new PS from Amazon.com in the UK. [/QUOTE]
