blank screen

[ames]

I have had this for a little over a year, it use to work with no issues. Now it doesn't work. The other day I uninstalled it and reinstalled everything and it worked for one day. Now it no longer works again. It shows that it is connected but it doesn't show anything on the screen. I have attached the information from the system scan that says it passed. Please help, really need the 2nd screen for my job.
