Having a hard time diagnosing what is wrong

So this all started 2 days ago I was just watching a youtube video and I get DVI:No signal to my monitor, everything else is working. I turn off my computer, turn it back on and everything is fine up until the Windows Logo (Log in screen) and I get DVI: no signal again.
I use my HDMI coord to hook up to my monitor and everything works, I just can't use DVI for 144 hz.

So I try pretty much ANYTHING I can find on google for how to fix this, and I figure out I can only use the DVI when my graphic card is disabled, or I am in safe mode. Leading me to believe it may be my graphics card acting up

Computer crashes again, this time the computer is running fine on restart, but NO ports work at all.
After trying a number of 'fixes' on google I take my 2 sticks of ram out, blow on them and clean them out, stick them in 2 different slots, and the computer fires up with ports including DVI working with graphic card enabled! So I am now thinking that it must have been a ram problem

After another 3 hours of thinking everything is back to normal and I fixed my problem, my computer freezes. I restart it and i'm back to DVI: No signal , So I say fk it I'm done with trying to fix the DVI so I just move onto HDMI.

So this next day now, about 7 hours into my day everything is going ok on HDMI, fully accepted I can't use my DVI port since i've tried everything. Then it happens again, computer crashes.

Now, whenever I try to simply start the computer, it powers on for about 3 seconds with all the fans running - with a red light on CPU led and powers off, It will keep restarting and repeating this until I fully power off the psu. Now leading me to believe its the cpu or motherboard

Specs: Evga gtx 970, asus p8p67 evo motherboard, 750w gold standard psu, i7 2600k cpu, 2x 8gb gskill ripjaw x ram , asus vg248qe monitor.

So im quite confused whether its the motherboard, ram, psu, or cpu

I built this computer about a year ago, ANY help will be appreciated. Just need this problem diagnosed, because I am really unsure what to buy if I need a replacing and would rather not fork out hundreds of extra dollars.
 
Solution
That is part of the 'bread board' testing. The MOBO should 'error' beep that RAM is missing. If it doesn't beep there is no RAM, then the Mobo/ CPU is faulty and needs to be replaced. As for the CPU LED have you READ THE MOTHERBOARD MANUAL about it? Would be helpful then just blindly poking at things till 'something works'.
A) remove one component at a time, and test, if you get down to the last few parts (1 RAM, CPU, Mobo, iCPU) your looking at those or the PSU.
B) Try with KNOWN WORKING hardware (friend's PC, etc.) and swap out and see what happens over time. Again repeats A diagnosis
B) Considering the AGE of the CPU, I am more putting the finger at the CPU / Mobo failing than a 970. Simply because your having multiple parts having issues (RAM vs GPU) that the main components (CPU, Mobo, PSU) as most likely, but again you have a real nice PSU, so....

Will my computer start without ram in it or without working ram? I keep thinking that may be the issue

Also as I said the CPU LED red light is on.But Cpu fan starts spinning when turned on for those 3 seconds.

I tried removing the video card and the problem persists.
