Computer turns on without display

[Kuniscki]

My computer turned on and then off. After some tries it turned on again, bur there was no monitor display. I tested the graphic card, ram, power source, even bought a new motherboard but the problem is still the same. I tried tp press the on button for a minute but i didnt work too. Specs: i5 2500k, asus h61m-a, corsair cx600 v2, r9 270x, 4gb ram i coildnt find the box. Some components are from 2011

So you have tested every part independently, including the monitor, and they all work, but do not work together?

I havent tested the monitor cause i dont have another one and it is kinda new. But i tested with another motherboard, another psu, and both integrared gpi and the r9 270x, still the same problem with all of this. Same thing ror RAM

Tested with another monitor, same problem

If every part works properly by itself, or on another system, but not on yours, together, and both iGPU and GPU produce no display, that leaves few options.

1. Monitor is configured to expect input from a different port or format than what you are giving it.

2. Monitor cable to computer is defective.

3. Software issue with OS (more than merely drivers)

Could it be the cpu? I havent tested it and i dont want to buy one without being 100% sure.

 

[DonkeyOatie]

Possibly. Did you test it on another system?

 

[Kuniscki]

Nope. Gonna try to find some cpu to test

Doesn't need to be the same; anything that will run on your motherboard. I keep a spare G3258 around for Haswell, Z87 Z97 testing purposes.
