[QUOTE="SwissBuster, post: 1162552, member: 78168"] The help is much appreciated. I don't think the noise is coming from the power supply, but it's hard to tell exactly. Is there a way to test your theory about a failing power unit by removing other items that are draining power (if so, which ones would be the best ones?). I've never done it, but my guess is a failing PSU is a relatively simple switch (compared to changing the motherboard)? I need to think where I can find a PC with a PCIe slot and Sat connection to test the DD card. Another thought is that the PCIe slot on the motherboard has failed, so I can maybe test the slot with another PCIe card. When you say "full power cycle (ie. shut down + cold boot)", what do you mean exactly? I did remove the DD drivers completely (plus the 'hidden' ie not-currently installed devices under device manager), removed the card physically, disconnected the power supply completely [U]and[/U] removed the CMOS battery to give myself the best chance of win10 recognising the device on re-install. Also, what are "out-of-spec power rails"? Ironically, I now have a fully working system with 2 LAN connectors being recogised (I've now turned the onboard LAN off via BIOS) and MP working fine - expect no TV because no TV cards! [/QUOTE]
