So I was playing and suddenly my monitor went black and into "power saving mode". Both my keyboard and mouse had lights on but both were not responsive anymore either.
What have I done so far trying to figure out whats the case?

-Removed CMOS battery so it would have reseted bios, nothing happened, screen still black.
-Tried my monitor with different computer, worked flawlessly
-Tried to put my DVI cable to my motherboard instead of graphics card, nothing happened.
-Removed graphics card and tried mobo port only.

Computer fans keeps running as usual, I do not hear any beebs when restarting computer, it just rans as it should but no image :/
I do not have any extra parts to test with so if there is no "good way" to figure what is broken and if I cannot find help here / other sites I will just have to get computer fixed by someone who has extra parts to test with.
Any help is appreciated, thank you!

Yeah, I tested with HDMI cable with TV and with another monitor, still the same issue.
