Hello guys, I'm new here,

So my Graphics Card (Sapphire HD 4810) is lately on 82,5-85°C without doing anything! It used to be around 50-60°C. So now when i play CS:GO for example, it gets too hot and my PC shuts down..

I have cleaned the GPU so it's not dusty, I've scanned for any viruses (bitcoin miners etc.)

Any ideas would be really appreciated!

 
A virus is an unlikely cause, when you cleaned it did you remover the heat sink? if so you will need new thermal paste. also check that the heat sink is still tightly on. you card should have a fan based on the pictures I saw online, is the fan running?
 
I would say that it might be a bitcoin miner and here's why. I had a bitcoin miner on my PC last year and my graphics cards were getting hot when my system was idle. I ran a virus scan but it wouldn't pick up the bitcoin miner because apparently it's considered a safe program. So I downloaded a program to see what processes were using my GPU. https://technet.microsoft.com/en-us/sysinternals/bb896653.aspx Click the link to download process explorer. I identified what program was using my GPU and I ended the task but it kept coming back. Then I found which directory it was in and I used Ubuntu to delete it. Then everything seemed good in windows for a while but it came back. After that I realized it was being installed by a program I was using that I had downloaded from usenet. I deleted the program and just went ahead and reinstalled windows problem solved.
