Not sure if it's technically crashing or not, but, while playing games my monitors will shut off and say that they cannot detect a video source. The tower still has power and is lit up, there is no sound at all. I turn it off normally, but turning it back on is the issue. Pressing it once doesn't work, holding the power button, unplugging it and plugging it back in. Eventually with no warning it turns itself back on. Just wondering what could possibly be the cause of this? Thanks.
