Pc not posting, booting

[Nitrixtone]

My pc ive built, recently acted up upon playing games, random restarts. Its been going strong for almost 4 years and i cant figure out why all the sudden it just didnt do anything upon another restart... just showed a black screen and only cpu, gpu fans were on, all other sytem fans were off... including the Qcode reader. I tried to turn it on without ram or drives and different ram slots including taking out the little battery and reset the bios... but nothing. I need help of what maybe the cause of this.

Specs:
PS Corsair HX 750i
I7 4790k
Enermax dual fan cooler
Msi z97 gaming 5 motherboard
Gskill 8gb ddr3 1333
Hyper x fury 240gb ssd
1tb WD drive

Have you tried removing the GPU and booting off the CPU's integrated graphics?
