I recently bought a new computer case and successfully swapped my home build over to it. Near the end of the install I realized that the front cover of the case didn't allow access for a cD drive. I went ahead and finished swapping over the parts so I had a computer to play on while I waited for Amazon to respond to my review and refund request. Well they didn't offer an exchange so I had to swap the parts back over to the old case. Now it won't boot up. It says it needs to repair the install of windows and then goes to a screen where I'm supposed to choose a language but the keyboard goes dead so I can't choose anything. I tried 3 times and got the same result. Is there anything I could have hooked up wrong that would cause these symptoms?
