Came in today to find my PC screen frozen. There was a buring smell coming from the PC. When I removed the side of the case the CPU heatsink fan had stopped, adn the heatsink was very hot. I powered off the PC and left it for an hour. It restarted OK but instincts tell me something is cooked!
Given the CPU is still alive, is it worth replacing the heatsink & cpu ? Also I am struggling as to why the heatsink fan would have stopped - or is that a symptom of the cpu overheating and cutting out ?
