So I recently aquired a new Wacom tablet and I plugged it in this morning before turning on my computer. Whe my computer turned on it went to 'preparing auto repair' screen, then to a diagnosing screen and has said that my computer won't start correctly. I've so far tried all the troubleshooting options Windows has given me, which has been restarting the PC, resetting the PC both with keep my files and remove everything (both said the attempts were failed), system restore, system image recovery, start up repair, start up settings (which when clicked on wont let me choose any of the Fkey options after clicking reset) and the go back to previous build. I've also tried disconnecting the Wacom tablet, my keyboard and mouse, my worlds wifi stick, I've unplugged the power supply, and both the moniter connected to the PC. I have no idea what else to do and I've been examining the interior wires for disconnected plugs for around 6 hours now. I also don't have access to a disk copy of Windows because I bought my copy online and I do not have a disk tray for my computer.
