I build a PC and have been using it for a couple of years. I don't have a GPU, but have been able to play BF4 and 3 thanks to my APU. After a couple of matches (I normally play much longer than that) I noticed a burning smell. The smell didn't seem to fill the room, just around my desk area. The computer still worked, but i instantly turned off the game. The smell didn't seem to continue after that. I put my hand next to each of the vents in my case, and the air wasn't as hot as it normally is after a long game. I continued to shut off the computer and took off the side panel. I didn't notice any damage or busted caps. I put my nose closer to each of the at components, but didn't notice the smell anymore. There was a smell coming from the CPU area, but it didn't seem to be the same burning smell. I got a bit worried from reading other articles, but none of them seem to be my case. Any help? Thanks in advanced.
