My laptop became unresponsive recently. I searched for the root cause and I found out that my resource monitor shows 100 percent of Highest Active Time for the disk and not much i/o with it. The process causing this activity is mostly 'System' wit PID 4. But sometimes other stuff like 'svchost'. I tried new Intel chipset drivers, Matrix Storage, even a fresh install of Windows. Nothing helped. Any ideas?
