had issues with my pc freezing while loading on online pc game. i fixed 2 errors (3011 & 3012). i downloaded ccleaner and fixed the registry. problem gone. i did backup my registry before the repair btw. Later while playing my pc game online it froze again at a loading screen. Event manager logged error 2004. Looks like its affiliated with the sending/receiving of information. Whether the problem exists via lan/network, idk. Any suggestions on how to troubleshoot the event id 2004 critical error?
