Me’s got a problem

[DirtyHarry]

gday guys..............................Harrys at it again

I got a second pc which is the slave and it's connected to my main pc by a cross-over cable. It’s running with two hard drives, which I want to remove one and put it in the main pc. Can I just remove it and then reinstall it in my main pc?

But the problem is my slave pc when I switch it on I get a beeping noise, it lasts for about 3 seconds then stops then start again and the monitor is receiving nothing!

Need help asap…………………….
