Trouble with monitor on custom PC

[Nemo Wiren]

Hello!
I recently bought computer components for my custom build. I assembled it and it didn't work. There was no signal on the TV (that I'm using as a monitor for the time being,) but all the fans and lights were working completely fine! I took it to a professional, who was saying that the ASRock 970 Extreme4 I was using wasn't a particularly good motherboard. So I got the motherboard changed into an Asus M5A97 R2.0 Motherboard and installed it as I should. The exact same thing happens, no signal on the TV, but everything else was working! I don't know if it is the graphics card or so, but it just doesn't want to work. Here are all the components if necessary:

OS: Windows 8.1 64-Bit English
Chassis: NZXT H230 Silent Mid Tower
PSU: Corsair PowerSupply CX 430M 430W
HDD: WD Intern Hard Drive Blue 1TB SATA III
Memory: HyperX FURY Black Series 8GB 1333MHz DDR3 Non-ECC CL9
Graphics Card: ASUS GeForce GTX 760 2GB DirectCU II OC
Motherboard: Asus M5A97 R2.0, AMD 970 Socket AM3+ ATX
Processor: AMD FX-6300 3.5GHz 14MB – Socket AM3+

You need to try other video outputs. Odds are everything is working, just remember not all outputs on your video card are enabled by default. Some motherboards default to the onboard video as well until you change it in the BIOS.

what the make/model# of the tv?


Did the 'professional' connect to a normal display and everything worked ok?

Did you set the tv's input to match the one from the pc? How is the pc connected to the tv anyways?

popatim, The TV is an LG, don't know what model or so, it is kind of old. The professional tried to connect it as well but nothing happened. Then he told me to change the motherboard. The PC is connected to the TV by a HDMI cable which we use for our Apple TV and our Xbox 360, and the input is as it should be.

Mr5oh, I have tried a different output, but the same thing happens. No signal. There are four outputs and I have access to 3 of those. If it is the fourth one that is the default one, I don't know what I'll do.
