Why doesn’t computer POST after removing hard drive?
I have a P8Z68-V-PRO motherboard, 8GB RAM, a 500GB Seagate SATA that runs Windows 10 and a 250GB Seagate SATA that was used for extra storage. Since I planned on replacing the 250GB with a 1TB WD SATA, I formatted the 250GB from cmd (clear), shut down the computer, unplugged power cable and disconnected the hard drive. I then inserted the 1TB, reconnected power cable, but desktop will not POST (fans not running, no beep). I disconnected the 1TB, still no POST. I reconnected the old hard drive, still no POST. When I reconnect the power cable and turn it on, only the red power and green Reset buttons on the mobo light up, but the reset button turns off after few seconds. Only the red power button continues to stay on.
Do I need to press the reset button for it to work? And would it still work even if the light is off?
All help is greatly appreciated!
