Issue: Black screen following boot menu on LiveUSB

Impacted Versions: BT-Gnome-64, BT5-KDE-64, also tried BT-Gnome-32.

Details:
Following any selection on the boot menu I eventually get a black screen, as if the screen has been powered off. I have searched on the BT forums and attempted to use the login startx solutions mentioned to no avail. Nothing appears to work. I have verified the MD5 checksums and they match, so I have no concerns about the integrity of the ISO.

Also, I used both LinuxLive USB creator and Unetbootin, again no resolution. Any suggestions?
