my zotac 1060 3gb has been working for over a year now. i noticed it was getting dusty so i cleaned it with isopropyl alcohol . When I put back in it worked fine it booted and it was all good i went to csgo to play with some friends. I launched csgo fine and was in the menu for 5 min but when I started loading up the map my pc shut down when i tuned it on it wouldn't post. the fan was moving on the gpu but wouldnt post. i restarted my pc multiple times and wouldn't post. I am currently borrowing my brothers gpu and my pc works fine. Any ideas on how fix it?
