No video signal on my PC?

[Luke Benson]

Not via, graphic card or onboard dvi and hdmi slot. It was working for 3 months perfectly. No sign of an upcoming failure prior. The computer turns on fine perfectly but there is no signal. I tried two monitors and a tv.

I don't think it's the PSU, GPU or RAM. Pretty sure it is the MB so I'm returning it for a different one but what is the
problem? Sometimes if I remove the power cord and put it back it just doesn't turn on. Sometimes it does.

Here is my specs..

•Intel Core i7-4790k (stock)
•ASRock z97 Extreme4
•Cooler Master Hyper T4
•16GB 2133 (8GB x2 G.Skill Ares)
•EVGA SuperNova 750WG2 80+ Gold Certified PSU
•ASUS STRIX GTX 970 (stock)
•BitFenix Ronin w/window case
•LG Blu Ray UH12NS30 Optical Drive
•120 GB Kingston SSD (boot drive) *awesome, boot within 3 seconds
•18TB Toshiba 7200RPM HDD (mass storage, 6TB x3)
•Windows 8.1 OEM

It could be a board problem, but without a case speaker (for beeps), we can only guess.
