100% Disk System Disk Usage with only 0.1 MB/s

I am encountering a problem that is crippling my laptop. Over the past weekend I have been expierencing my laptop coming down to a standstill in processes it takes nearly two minutes to open up a page on chrome and running a game... forget about it. When I open up task manager it shows that 100% of my disk is being used but when I look at the processes using it all I see is System 0.1 MB/s. When i go into the performance tab of task manager and click on disk it reads:

Active time: 100%
Average Response Time: 0 ms then it spikes to a random # in the thosands
Read Speed: 0 KB/s (Like the Response time it jumps around)
Write Speed: 0 KB/s (Same as above)
Capcity: 932
Formatted: 931
System Disk: Yes
Page File: Yes


System:
Acer Aspire V-5
AMD A-10-5757M
Radeon 8650G and Radeon HD 8750M
8 GB Ram


Fixes Tried (Failed)

• Downgrading from 8.1.1 to 8.1
• CCleaner
• Disabling and stopping Superfetch, BITS (Background Intelligent Transparent Service), Windows Update, and Windows Search.
• A clean boot (I still encountered the same issue)
• Readjusting the virtual memory

I would love if somoene could help me with this issue as I need to use my computer and this is making it neigh impossible to do.

Exactly the same problem - Acer Aspire One.
I was having performance problems and ran chkdsk which found some bad clusters. Next thing I know, I restart and Windows won't come up. I could get a cmd prompt going and copied out my files and reset the system. Still nothing. Finally got it going by turning it on and plugging in a recovery flash drive. Completely reinistalled 8.0. Installed 126 updates. Installed 8.1. Installed 26 updates. And now I'm smack in the 100% disk usage.
Tried setting Virtual Memory, which was small.

Have you tried the resource monitor under the task manager performance tab? The resource monitor lists processes and services. After updates my laptop is frequently unusable as defrag and Norton 360 backup contend reading and writing the updates across the disk. Running until the disk is defragged and backed up fixes the problem in some cases.

Well, maybe it just needs patience. After letting it run all night, it seems to have done whatever it was doing, and no longer pegs as soon as it's restarted.
