After upgrading to Windows 10 my pc started flashing so I downgraded to Windows 8.1 but I’m still flashing. I went to the geek squad to check for a virus and they said there was none. When I got home it started flashing again. Is something wrong with the GPU or my screen?

Does the screen flash in any particular position ? Is it when its in the tablet mode , or tented ? Does it flicker when you wiggle it, will it work properly when you dont touch it? I have had to replace the LCD cable on this model it tends to crack in the hing from the extra flexing when set up as a tablet. If the screen does not flicker with an external monitor attached as jeyeff mentioned its probable the cable. If it still flickers you may want to reinstall drivers . If you get no joy there you may be looking at the GPU starting to fail
