- system won't post with hard drive plugged in

system was running fine and then it it would not turn on the next day. I
replaced the motherboard and powersupply and it still wouldn't boot. I
unplugged all the peripheals and it booted. Then I plugged in the cd rom
and floppy and it booted, when I plugged in the hard drive it will not
boot. It's like I'm not even pushing the power button. I tried other
hard drives and the system will boot. I tried that hard drive on other
motherboards and they do the same any ideas?
Re: system won't post with hard drive plugged in
If you fail to boot due to the HD being attached and it displays the
same symptoms on another computer, a good guess would be a grounded data
lead on the logic board for the HD. Although it is difficult to do, a
reversed data cable on an IDE HD will ground out data/address bits and
negate the booting of a computer in MOST cases. If you want to use the
HD that is failing, seek an identical logic board and you will probably
be able to access the data.
