PC has no signal to HDTV via HDMI cable..
UPDATE:
Heya, I've just finished building my first Gaming Desktop PC and have followed a YouTube video word for word with installing components and wires/cables and it's all been correctly done (to my knowledge so far). There's a slight problem with the connection between the PC and the HDTV now.. there's no signal on the HDMI source (and other sources I've checked on the TV).

This is the new problem I face, I have a XFX Radeon HD 7950 GPU and it has a HDMI port which I used to plug the HDMI cable into and then into the HDMI slot on my HDTV. Basically it's just a black screen with my TV message saying "no signal".

Any help?

Faulty power connections, forgot to plug in motherboard to power supply, missing connections, bad motherboard batteries, etc ,etc. The factors that may cause your problem is pretty much limitless.

Those small cables could be in wrong place. Check the manual you got with the motherboard. It should have info on how to put in them correctly.

I've just bought the motherboard a week ago and fitted it in yesterday, the PSU power supply to the motherboard is connected, the batteries look fine and not damaged... Should I just pull apart my PC and get a professional to build it? Only thing I can think of...

POWER cable is what sends a signal to the power supply to turn ON. If you didn't connect that one, it won't power on. If it still does not work, turn it around.

It's odd that you acknowledge the 'obvious' missing power connection, but still ask for help.

Check your manual carefully.

I think the only problem I have currently is the power button... the PSU is definitely connected to the motherboard correctly since that plug is unique and only fits into a certain sized slot. It's just that the "POWER" Labelled plug that came with the PC Case hasn't got a designated slot on the motherboard to fit into which is frustrating...

The manual for the motherboard should tell you exactly were to plug it in.

What motherboard do you have?

GA-990FXA-UD3 Motherboard

and Aerocool XPREDATOR X1 (Midt Tower) Desktop Case.

Response to TheBDK: There's a part in the manual about the Power Supply:

"Connect the power supply cable to the power connector in the correct orientation.
If the 12V power connector is not connected, the computer will not start."

Considering I somehow work out a way to fix the connection from the PSU to the motherbaord I still can't use the power button on my PC Case because it can't connect it's cable to anywhere on the mother/PSU.

Go to page 25 in the manual. It's the prongs labelled as 19 in the picture.

Or your case may have one big connector for all of that. (I didn't look that up.)

Thanks for that, I just got the Power LEDs in the right place now. There is only suppose to be one cable connected the Power Supply and the motherboard right? (the 20 odd wires bunched together in a single cable).

There is generally a four or eight pin molex connector near the CPU also... and if it's not plugged in, the board won't post.

Pages 22-23, section 1-8 of the manual shows an 6 8 pin connector labelled ATX_12V. This must be connected.

Hmm, first time I've seen a six pin, iirc.

Yeah I have that connected aswell


Response to Silicon Vampire: Yeah that and the other ATX were one the first things I plugged into the motherboard.
