I currently have an old NEC slimline desktop PC bought in 2004. Just recently, I used winASO reg optimizer to clean out its registry errors and optimize the system. To make sure everything’s fine, I rebooted the system once and it worked like a gem.
However, the next morning when I switched it on, the fan motor was at full blast and it just stagnated at that point, nothing happened the boot screen wasn’t there, the monitor was on standby mode and there was a slight burning smell. I do not know what is wrong. Is it a hardware problem?
