Screen flickering black and grey

Since January 12, my Envy m6-1184ca would get a flickreing screen. I would press the power button and aftet the HP loading screen, my screen would start flickering black anf then grey. I believe that me, uninstalling a theme is the problem (RazerRed is the name of the theme). Any help would be very much appreciated.

Note: I can't go on the desktop
