Hi

So you have 2 PC's

1 works and is not a problem, it's A

The other has a black screen, call it B

So A works with both Hard Drives?

B works with which hard drives?

[masterflex093]

a, does work with both drives connected. b, doesnt work at all with neither of the hard drives. but a, only works with b's hard drive threw usb not internally so...... idk

Hi

So you have a fault in the connector and/or main Board I guess.

Try B with a USB flash drive, and no HDD fitted, and Lubuntu instead of Winows.
