Maybe still a problem?
EDIT 2: The HDMI cable seems to be fine now which makes me wonder if the problem isn't something else, so if you have any ideas they would be much appreciated.
EDIT: it appears to have been a bad HDMI cable.
I woke up this morning to find that my computer is not working. It boots up the motherboard but with a bunch of blue lines and never boots up the OS be it my Windows hard drive or my Linux drive. I'm thinking it has to be my motherboard or graphics card since my monitor is hooked up to that because my motherboard doesn't have anything to hook a monitor up to. But before I start tearing things apart I was wondering if anyone had any advice?
