Virus TI black screen?? (Not working)

[Fitzgrade]

Well im a new virus user. I had it working in fl studios with the latest OS but i then uninstalled that and installed the last OS because things were not syncing up properly Latency was unsyncable. Now i have a black screen and cant see anything?? Also i bought this from a guy in America so its power supply was different i found an adapter but everytime i plug out the power from the back of the virus then plug it in again i get sparks is this the cause of the black screen.

And ever since the start i have got the error messege ''The data is invalid'' when installing the OS4?

And when i try to uninstall the OS for the new again i get a messege after my computer reboots that the virus failed to reboot??
Even with the power connected there is no lights blinking.
Is it broke?
