Hi, when my I power up my pc it had red vertical covering the whole screen. I can see the gigabyte logo when it boot up then when windows is loading the red lines glitches across the screen after loading it lead to a black screen, my monitor wasn't receiving signal from my pc. I power on and off my pc via power button i took many times until it loaded properly. Do you have any suggestion on whats happening to my PC. I took my hard drives off knowing my OS cause it but it keeps happening. Please help
