So i was watching tv today and my mac was sitting on the table, and i noticed on the screen saver the screen was just flashing very fast, when i went to wake it up it got brighter continuing to flash but would not respond. i was forced to turn it off by holding the button down, after that it would not boot. got to the spinning wheel and the wheel froze, after going into single user mode and doing a check on the disk which found no problems, it booted up but once in it froze for a few seconds, then the screen began flashing and then random glitches with the screen began, as can be seen on the photo i will attach. and the screen is continuing to flicker and stuffs showing up weird. is my mac finally kicking the bucket? oh also the glitches on the screen seem to relate to when the computers doing work, not when actually touching it so it doesnt seem to be a bad cable to the screen.
