Hello,
I have bought and been using Radeon rx 470 for a few years. It was working fine until I opened up the computer case to clean some dust. I vacuumed the entire inside including the graphics card. Also, I noticed the card was sagging, so I put a stick where it was sagging to level it. I did not remove any wires or cards.
Then I turned on the computer and then the first thing I realized was that resolution was not the same as before. It was much smaller (size of icons got bigger). When I turned on starcraft (the original, not sc2), the animation on the menu was lagging and my mouse was also lagging. I don't know what is going on. The device manager says the device is working properly but the gpu is apparently underperforming. I tested with other games and the result is the same.
How can I fix this issue? What has gone wrong?
Please help!
