I am assuming you have everything installed on your PC. Not sure what DM you are using, 7.0.0.0 or .20 or the latest one. I connected my device to my PC and cycled!battery pull while still connected to the PC, it should detect your device.

Do you have Desktop Manager installed, along with whichever OS you want to re-load in the you BB?
To wipe, download BBSAK as other have mentioned (google for a download link), then run it with your phone attached - it should recognize it even with your white screen. Choose the wipe option and when complete you should be left with a white screen on your phone, but this time it will say re-load OS. Then follow the basic steps to re-load an OS and you should be back up and running.
