So i built my gaming pc in December of 2020. It works great, so its not an old system by any means. I decided to clean it in June 2021, used compressed air and unfortunately while i was blowing dust out of the power supply some residue from inside the can came out and shorted my PSU Got a new one the week after, so i go to clean my PC again today and decided to stay away from the condensed air cans and just used a very small battery powered blower to clean the dust with a dry rag. AND MY PSU WENT BAD AGAIN SOMEHOW! I have no idea how but if anybody can tell me if im doin something wrong? Has this ever happened to anybody else. PLEASE HELP!!
