PC no longer connecting to TV through HDMI.

I've been using my tv as a monitor for my pc for almost a year now via an HDMI cable. I've had no issues since day 1. I just plugged it into both devices and it's always worked. All of a sudden though I just get a "no signal message on my tv when I turn it to the input the pc is plugged into. I have two HDMI cables I've used both cables in both HDMI slots on my tv as well as tested the cables out with other devices and they all work. The only thing I can think of is that the HDMI port on my pc fucked up somehow. It doesn't appear to be loose and the cables fit firmly into the connection. I don't have a monitor to plug into the pc so I'm kind of out of options for trouble shooting. Can anyone think of anything else? I broke my foot recently so my activities are kind of limited to using the tv. I don't have cable or a game console so this pc provides my games, Netflix etc... Like in said I've had no issues for almost a year now. I turned it off for like 2 hours went to turn it in and this shit happens.
