Hello folks, a couple days ago everything was fine untill i turned my pc off for the night. After that, the computer seems to boot up but does not display anything at all on screen (screen keeps saying "no signal").

Specs:
Mobo: GIGABYTE 78LMT
CPU: AMD Phenom II X6 1055T (6 core 2.8ghz)
GPU: AMD ATI Radeon HD 5770
RAM: 2x4gb
PSU: acbel ce2 450

Here's a couple of things i have tried so far:
Switching HDMI cables.
Testing video card in different computer (It worked).
unplugging power cable and holding power on button for 30 seconds.

I don't believe it would be the motherboard since it is still very new (2 months old). I do not own a multimeter to test the power supply sadly. Is it possible that my cpu has just had it's time (4 years old)?

Any and all help will be greatly appreciated!

I tried the HDMI port on the motherboard and it still did not work. Should i try test it with a VGA cable or would it make no difference?

Just tested both ports on both the gpu, motherboard and TV/Monitor. Still sadly, no luck.

Try taking the battery out of the motherboard for about 60 secs then putting it back in. Did you try updating your bios recently? This happened to me a while back back when I tried to install a bios update from an online site.
