huge thanks

my card is a
Sapphire Radeon R9 280X Dual-X OC 3072MB GDDR5

.sorry i tried to upload the pic but it wont let me
 
does sound like GPU.

take it out and try onboard graphics if available or better yet a different GPU but my bet is GPU.

Does the lines and squares show up right away or after a min or two.

Squares on screen can indicate faulty GPU ram or over heating etc.
 
ok well very unlikly but

remove refit HDMI cable or DVI cable etc what ever ya using (insure its in right)

I am thinking the GPU is borked though

I think we can pretty safely exclude monitor breaking from candidates
Broken monitor should give similar "error" with every kind input picture.
GPU is the most likely cause.
 
after many resets and cable tests and cleaning i got it to load up without the red bars showing and now i can go back on my game which was ARK and after 5-10mins my screen just goes blank with very thin vertical lines but they are very thing and the screen almost looks orange tinted. i have no idea at this point as i thought all was well. thanks very much for the help so far
 
I'd say (and this is very much conjecture) that it's overheating. The 5-10 minutes you mention before it happened again makes me think that dismantling and applying new thermal paste might help- I'd imagine that the stuff on there is pretty powdery by now. No issues most of the time, but as soon as the weather gets hot, it tips the balance...

do you mean on the gpu?
 
the fans on the card sound a lot louder than before, even tho its very clean, the socket seams a little loose so the fans kept stopping as well

Ok. See the graph at the bottom, where it says "GPU temperature"? There's a "Min: 40" and "Max: 41" reading over to the left? Play your game for a while (10 mins or so) and see what the "Max" reading says afterwards.
