Ok so at first I thought it was a graphics heat issue but now thats not the case. I get red boxes soemtimes through my screen but that is fixed by switching monitor inputs back and forth or turning the monitor on and off. Now today I went to use my computer and the screen kept flashing on and off like 1 sec of desktop and 1 sec of black and so forth. I turned off the monitor and turned it back on and it works again. Monitor issue?
