I\302\240researched\302\240and put things\302\240back\302\240together, but seem I have Three white connectors and one black\302\240coming\302\240from wiring harness to hard drive that are not connected to anything. Its this right? the hard drive is connected. I have stripped this computer down to frame to see if any\302\240connections\302\240I missed and all seem fine.\015\012\015\012DVD drive connected\015\012CD Drive connected\015\0129in1 memory card reader connected\015\012Hard Drive connected\015\012Motherboard connected\015\012\015\012\015\012Question 1: Why would computer just start with the blinking green in back after reboot (yes I pulled power supply after shut down then plugged back in after 10\302\240minutes\302\240and blink ahoy!!!)\015\012\015\012Question 2: Is there a\302\240wiring\302\240schematics to help me locate all correct wiring positions and an\302\240explanation\302\240of why or how many loose\302\240connectors\302\240should\302\240have. I realize some are for expansion, I just need a clarification on what goes were.\015\012\015\012Question 3: What would cause a motherboard or power supply to just blink im done. I realize this is the circle of the electronic life cycle but WTH!!!\015\012\015\012Question 4:\302\240What\302\240are my next steps to locate the underlying issue and replace that beast so I am operable again.\015\012\015\012Thank You in advance for being a help to those who want to know but have yet to get all of it!\015

Answers :

These wires vary based on the type of the board each wire lead is labeled to coorespond with the pins on the board. You need to reference the manual for your specific motherboard. If you don't have the original get it from the vendor support site or just google it. Unless your motherboard is an odd brand it should be easy to find.
