HDMI not working with TV "No Signal" - do I need a new Graphics Card?

Hey guys,

For the past few years I have been running a HDMI cable to my TV. I also have a DVI going to a monitor. I have it so when the HDMI is in, the screen is automatically on TV, if HDMI is out, it will go to monitor - ease of use when watching films on larger screen. Zero issues up until now.

Now though, the HDMI to my TV has 'No Signal'... But it is recognising that there is a HDMI source as when it isn't plugged into my PC it says 'No Cable Connected'

Seriously stressed out over this!

I have tried:

- Other HDMI cables
- Different HDMI ports on my TV
- Plugging HDMI into the back of my Xbox One's 'HDMI IN' port
- Updated my ATI drivers
- Booting with just the HDMI plugged in, no DVI


So PC folk, is this a Graphics Card issue, HDMI port issue, PSU issue, or hopefully simple settings issue?

Specs below:

AMD Radeon HD 5700 Series
Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (8 CPUs), ~3.4GHz
XPS 8300

Windows 7 Professional 64-bit (6.1, Build 7601) Service Pack 1
BIOS Date: 10/17/11 11:18:49 Ver: 04.06.04

Sometimes TV's wont recognize the connection. Hook up the hdmi like always, with the computer off. While connected, turn on the computer and see if that helps.
