My laptop (ASUS G73jw) sometimes gets in a state where it will repeatedly (every 10 seconds or so) "freeze" - the Task Manager CPU usage goes to zero - and then recover after a few seconds. The HDD light is on during the freeze.
Having browsed for a solution, I have installed Windows Performance Analyzer, which shows clearly that during the freezes:
- the CPU is idling
- the Disk I/O stops
- the Disk usage is at max(!)
I've run chkdsk, no defrag needed, etc etc. The disk is a Seagate Momentus XP (hybrid SSD/HDD). I tried Acronis Drive Monitor but it says the drive is healthy.
What else can I look for?
