Around 20 years ago I had a new motherboard fail to post, and the store who sold me the motherboard told me to disconnect all hardware except graphics card and monitor and reconnect hardware 1 at a time restarting after each device was reconnected if it posts with only the video connected, but the PC still failed to post. The store said the motherboard was bad and replaced it. A couple of years later the same problem arose with another PC, and the same steps were followed resulting this time in PC booting after all hardware was reconnected. I’m unsure why this works, but it does.
This afternoon I followed that same procedure, and the new motherboard booted until the last optical drive was connected whereupon it froze at the same point in my initial post above. A second sara cable was tried with no help; then I tried switching sata ports with the problem persisting. I also tried switching sata cables between the 2 optical drives, and the problem continued. Finally I determined the system would boot correctly only when that last connected optical drive is disconnected. Apparently a bad optical drive was the cause of the problem. I’ve never had a bad drive cause this kind of problem. All other drive failures I’ve seen simply resulted in the bad drive failing to read or write.
Now I wonder if my conclusion may have been faulty about the motherboard replaced being bad, and could that bad optical drive have caused the computer to cycle on and off without booting. Maybe that motherboard isn’t bad after all.
There’s 1 more thing I need to determine. I’ve been dual booting WinXP and Win10, and while using the board that was replaced sata mode in bios had to be set to ide in order to boot WinXP. This new board has no ide setting for sata mode in bios. Does this mean WinXP won’t run on this board, or is there a way to boot WinXP without sata mode set to ide?
