You installed W7 on one PC then moved it to another. That is known to fail and folk that don't believe learn best from trying it.
Now that you know this doesn't work, can you share why you don't install Windows 7 when directly to the PC you want to run Windows 7?
Alright here goes
I’ve built a new computer and am trying to install windows 7, soon as it loads to the first screen the mouse and keyboard turn off. Now I found a work around by plugging my new hard drive into an old computer and am able to install windows with the same mouse and keyboard and they work. I then put the hard drive back into the new computer and load to a proper screen in windows however the keyboard and mouse still do not work. So I put the hard drive back in the old computer and installed the drivers for the motherboard of the new computer, put the hard drive back in the new computer and my mouse and keyboard still don’t work.
