PC crash vertical gray lines, now wont start.

I was playing league of legends and my PC froze with grey vertical lines on both monitors. I shutdown the PC by pressing the button. Immediately after when I turned it on, the hardware would boot up fans and lights, however no display was seen on either monitor. Figuring it might be my graphics card, I unplugged the DVI connectors and plugged them into the Mobo itself, however still nothing. I then unplugged the PC and reset the CMOS by taking the battery out and placing it back in. After that I plugged the PC back in and now it seems to not turn on at all, PSU doesn't seem to work at all, not even the orange light from LAN cable. I'm guessing this problem was the PSU the entire time? The PSU is the EVGA NEX750B

My specs

280x toxic sapphire edition

16gb ddr3 ram

H97 Pro 4 asrock mobo

i7 4790k with heatsink

Alright Ill try this then, do i have to completely take out GPU or just unplug?

And also do you think its pretty much guaranteed the PSU, because of the fact that not even the Orange LED from the ethernet cable is on anymore?

Still nothing

tried taking it out completely however PSU still shows no signs of life.No fans no LEDS, nothing. What does this mean?

Next step

Replace the cmos battery.

It's the cheapest part.

Are you sure?

What makes you believe its the cmos battery rather than the PSU? How could it of broken?

I don't believe anything

It's the cheapest part of what's left.

If you would rather replace the psu.... go for it.

Will test then.

Well I will test a new CMOS battery, and PSU tomorrow. I will post the results and we can go from there. Thank you very much I appreciate the help!
