Hi, I am back again with the same problem. My C: drive is always being used 100%. At the startup it is really slow. Some programs can't start properly. So after some time it gets back to normal speed and performs good. After some time it starts again... I have tried all the solutions I could find. (Like disabling Windows Search service and superfetch) None have helped. I am the point of throwing my computer to the dumpster. Please help me...
