So my custom desktop which I've had for several years has finally produced a problem which I'm completely stumped on. When I turn on my PC everything runs fine, the GPU, CPU, flashy lights, everything, EXCEPT for the monitor, which just displays "NO SIGNAL" when I turn it on.

 

I've tried EVERYTHING I could think of: switching and fidgeting with the RAM; replacing, cleaning, even switching the graphics card; changing cables connecting from the GPU to the monitor (tried 2 HDMI and 1 DVI); and even replacing my brothers monitor with my own (it worked fine with his rig).

 

My Specs are:

- Graphics: NVIDIA GTX 970

- CPU: AMD FX-6350 6-core

- Motherboard: GIGABYTE GA-970A

- Monitor: AOC 62460VQ6 24"

Does your brother's monitor work on your machine?

Your monitor is obviously working so the next item to look at is your connection cable and then your video card.

 

Try a different cable first since this is both easier and cheaper than a card - borrow your brother's cable if necessary !

 

If it still doesn't work with a known good cable, then the next suspect is your video card. A quick look at your  mobo's specs shows that it doesn't have on-board video so you are going to have to take out your present one and fit a different one. Since this is only for test purposes it doesn't matter too much how good it is so long as it is known to work. Your brother again ?

 

These two substitutions will determine where the fault lies. If it still doesn't work - with a known good cable and a known good video card - then you are looking at a mobo fault.

Late addition :-  'a mobo fault' - Just possibly a PSU problem since I see your video card draws up to 145W at maximum output.
