100% Disk Utilization in Win - System Freeze

I installed Win8 over the last weekend. Things were working fine for the first five days. Just day before i started seeing apps being unresponsive and noticed that the Task Manager showed 100% disk usage. The process taking the most disk is 'System'

Yesterday things became worse; the startup started taking way too long; after starting up launching any app takes up to 10 mins and the HDD led is constantly on; making the sytem completely unstable and stuck.

I have the following conf: Dell Inspiron 14R N010, Core i3 (1st gen), 4 GB, 500 GB Hdd (45% free), Win 8 Pro

Guys - please help!!!

I'm having the same problem with my Inspiron N5110 15R.

At first, the Antimalware service was the problem so I turned off Windows Defender. Now it's usually System.

Here's one idea, that it's a driver issue. And here too.

Here's one way to run diagnostics.

I solved the problem by removing Google Chrome. Due to some problem in update, the chorme initializes a process "Google Crash Handler", which uses 100% of the processing machine. The procedure I did is simple: Uninstall Google Chrome Google, delete the "C: \ Program Files (x86) \ Google" folder (Note: You can only delete the folder if the process GoogleCrashHandler "is finalized), restart the computer and reinstall the same ... Problem solved! (At least for me)
