So a few months ago I bought a new 144Hz monitor, I didn't have the cable so I just used HDMI for a while until I finally got around to buying the DP one.. Now, when I finally plug it in, there's a red light on the bottom of the mobo (when it's turned off). So I go to power it on, and the first time I do it, it starts up and shuts off immediately. The second time, it boots, but the LED screen stays at "00" since the beginning and doesn't change. However, if I change the cable it works fine. What's up with that?
