[QUOTE="mm1352000, post: 1162589, member: 82144"] No, not a definitive way. Yes, that would be a good test. (y) I mean Windows shutdown (ie. PC fully off - no need to disconnect power, CMOS battery), wait 10 seconds for power to drain/settle, then turn on the computer again (cold/clean boot). To be clear, I gave that advice because it seemed like you were expecting Windows might detect the missing network interface after "reboot" (which I assumed meant Windows restart). If you want Windows to detect missing hardware, my experience has been that restart is insufficient because the power is not removed (and so the hardware and BIOS are not fully restarted). Sorry, engineering jargon. :oops: It's too technical to explain in full, but in short: [LIST] [*]"Spec" is short for "specification". [*]A "power rail" is a power supply output with a specific voltage (eg. 12 V, 5 V, 3.3 V etc.) and current limit (eg. 15 A). [*]Power supplies must provide certain rails where the voltages must be within certain minimum and maximum limits according to ATX specifications. [*]If a power supply output voltage is not within the allowed limits then that is an "out-of-spec power rail". [/LIST] I've been thinking about this situation more, and I'm more convinced that the motherboard is not failing. The onboard LAN controller is likely to be part of the chipset which also contains the SATA storage controller, IDE storage controller, USB controller(s), PCI controller, PCIe controller etc. If the motherboard were failing due to chipset failure, I'd expect other functions (eg. storage) to be affected as well. More questions... Your motherboard has 2 PCIe slots - one x16 and one x1. Which one were you plugging the tuner card into? I assume you connected the tuner's power connector? [/QUOTE]
