I was on my PC and was running a high demanding game but my PC is powerful and cost good part of 700 squid so it can run it fine normally! And my PC suddenly Made a loud bang noise ( I couldn't hear it properly Because I had my ear phones in) and then turned off, and it wouldn't turn back on! So I checked my PSU and it had a funky smell.. So I checked the fuse and capacitors and there not swollen or burnt by the looks of it.. I have also had a ruff check of the rest of my PC mother board ec ec but I carnt find anything! Please Help
