Hi, for long time my screen is crashing, and it freezes as seen on the link. There occurs many little squares on the screen. I tried each output of the graphic card and the results are same. Whether DVI or HDMI, each one crashes. Actually even when i firstly turn the PC on, at the beginning, before the Operating System boots, it is crashing anyway. I couldnt find any correlation about that, it can be crashed randomly anytime. A few seconds later after this little squares, it turns into dark black screen totally. Then I reset the PC, sometimes it works well but sometimes i need to reset it 5,6 times in order for PC to run as usual. My motherboard is GA-870A-UD3. I even tried to change the slot of the graphich card on motherboard, but the problem existed anyway. My driver is also up to date. I am giving 2 links for 2 different figures, one of them is the crashed screen and the other one is from conflicts/sharing menu. I hope these information would be enough for a good observation. By the ways without any changing in hardware, the PC was running pretty well till that day. But suddenly something happened with my graphics card. When i changed this graphics card with my previous old card, the problem disappers. What can cause this problem, is there any solution to that? If u help me with this issue, i would really appreciate it.
