Is it the CPU or Harddisk that is working full time when it happens?
Open 2 Resource monitors, one with CPU selected, other with Harddisk. Sort by usage. When it happens next time, check these 2 windows and see if you can pinpoint the culprit.
I have 3 harddisk. 1 is c where is the system and have around 7 go free, the other d has 150 go and F system reserve has 99.9 mo.
I use wise care 365 so i have in the back the temperature and memory usage. temperature of haddisk is 40 (celsius)and processor is 55 and memory usage is around 70 when it happens.
How to I open the resource monitor ?
Correction. You have 1 harddisk with 4 partitions.
The OS partition (C:\) has 12% free which is just below recommended 15% (some say 10%+ is enough).
Please do this (you can start Resource Monitor, by opening Start Menu and write "resource" in search box):
Open 2 Resource Monitors, one with CPU selected, other with Harddisk. Sort by usage. When it happens next time, check these 2 windows and see if you can pinpoint the culprit.
