Grey wire is used to report to the motherboard that the PSU has passed all tests and ready to work. Some motherboards have hard times recognizing good signal, as result the motherboard will not start.
Power supply or motherboard is bad.
It is the Accelerated Graphics Port on a motherboard for attaching graphics cards.
The flashing amber light on a Dell PC means there is a power problem between your power supply and motherboard. Chances are its the power supply, but it could be the motherboard too. Typically this will happen when the PC is put under high-heat, bad ventilation, or dirty/dusty vents.
If the motherboard powers up but does not post, turn off and remove the memory sticks then restart, if the board is good you should get beeps from the board letting you know that the board has a memory error, if no beeps then it is possible the processor is bad, get a known good processor and if still no beeps then then the motherboard is toast
What does the question even mean?
The Northbridge is one of the most important parts of a motherboard's architecture.When it goes out there's not much you can do about it except get a new motherboard.
If you mean the motherboard you can go to ebay.
I believe you mean a "motherboard". This common computer hardware connects the central processing unit (CPU) to all of its peripherals (input, output, signaling, and storage devices). It is also responsible for drawing power from the power supply unit (PSU) and distributing it to all of the integrated circuits (ICs) that are attached to it. Permanent and removable media devices typically draw their power directly from the PSU, while the motherboard routes power to USB devices, input devices, CPU, RAM, and the various IC chips and addon modules (such as PCI and ISA buses) that operate from the power matrix that the motherboard supplies.
Phase LEDs display how much power the CPU is effectively receiving. If all 4 LEDs are lit you are good to go and shouldn't have to worry about anything. If they start blinking good luck on trying to find info on them, google doesnt even know man.
To be specific, I don't mean the power adapter , but the part it connects to. The part you plug the charger into. I need to know the name of it so i can replace it.
The motherboard, or "mainboard" of a system is given away by the name. It is the main component to a PC, as everything else tends to connect to it. for a more detailed explaination, check out this link: http://en.wikipedia.org/wiki/Motherboard
It used to mean sun power strength and good luck.
