So I got a computer built around a year and a half ago maybe, and ever since then, things have been a little off. Like occasional BSOD's, and my card (R9 280X) didn't seem to be performing at the level it was supposed to. The crashes soon became worse, and if my computer did recover, it would show the message, "Display driver has crashed and and has successflly recovered". I haven't been able to replace it due to personal problems so far, but now I can. And the last week or so, the computer hasn't even been starting up, it just shows a light blue screen (you can see it in the video I linked). The thing is, I want to be a 100% sure that it's the graphics card that's causing the issue, because I don't want to waste my parents' money. Could you guys help me out please?
