When I disconnect it the PC works fine

Please Help

It is rare that such issue is directly related to the hard drive. Ensure that the computer system is configured for optimal performance. It is recommended to connect the hard drive directly to the computer’s USB port and not the USB hub, try out different USB cables and USB ports. Connect the drive to a different PC to isolate the issue.
