So yesterday I was on my computer and it kept randomly shutting down and my tv went to like a green screen so I turned computer off and on and it started back up but then it kept shutting down doing the same thing, I manged to get it work again last night and then today it's been working fine all day since 11am when I turned the computer on and I just went in to a league of legends game and my pc shut down again and my tv turned green again, and now I can't get it to work. The pc itself still boots up like it did yesterday but like yesterday it keeps saying no signal on the tv, I've checked all wires and they are in and the hdmi cable is fine and the power is still fine as the whole pc starts just gives me no signal and even when I somehow fixed it last night it's doing all the same stuff as it did yesterday by randomly freezing with a green screen, and on my motherboard I have a little number thing it was saying A0 earlier but now it's saying A6
 
Oh it's not overheating as all fans are working and clean and I have taken the side casing off to help air it more
 
I've taken the ram out as well and put back in and changed slots, that didn't work I have also made sure all wires are securely in place too
 
Okay heres a little update,
Took our my Graphics card, pc started up fine, played a game, worked fine, done a stress test everything worked fine, so far my pc has just crashed and given me some random green screen
so i thought id try put my graphics card back in, gave it a clean up so its dust free put back in connected up the power, the fans start spinning but again no signal to tv, so i take it out and turn pc on and now it works again, Tomorrow im going to try put it in another slot of the motherboard but from what ive explained does that sound like a dead graphics card? even though the fans still spin?
 
Nope, since i took out my main graphics the pc turns back on fine, and then i put the graphics card back in and i got no signal again, so now im on my pc but had to take my main graphics out, all i get is so signal to my tv with my main graphics in, does that mean my graphics card is done now?
 
The PSU I'm using is a XFX CORE SERIES 650 WATT PSU
and I don't know if this helps but i took out my Graphics and i done a stress test and it was fine, i only did a 4gb stress test when i can do 16gb as i have 16gb ram, should i do a max stress test? would that help find out if the psu can handle it?
