Do some Disc Checks ....

1. Update your SSD's Firmware
2. Reseat the sata and power.
   
3. Run chkdsk /f/r, following the option two of the tutorial Disk Check
4. Seatool for dos: SeaTools | Seagate download
   Burn it in a blank cd. boot from the CD, click on "Accept", wait for it to finish detecting the drives, then in the upper left corner select "Basic Tests", then select "Long Test" and let it run.

Upload a screenshot of your HDD using CrystalDiskInfo - Software - Crystal Dew World

Download and install CCleaner. Then run it.
Go to "Tools" .... by default it will open the "uninstall" tab.
Click on save as text file. Save it on your desktop.
Upload the text file for us.

I suggest you to uninstall this one.

Code:

Intel(R) Rapid Storage Technology    Intel Corporation

The associated driver is very old.

Code:

lmvm iastor
start             end                 module name
fffff880`01010000 fffff880`013b4000   iaStor     (deferred)             
    Image path: \SystemRoot\system32\DRIVERS\iaStor.sys
    Image name: iaStor.sys
    Timestamp:        Wed Nov 30 09:09:19 2011 (4ED5A567)

    Translations:     0000.04b0 0000.04e4 0409.04b0 0409.04e4

And, it is nothing must to be there. First uninstall it in Control Panel> Programs and Features, then do it as an addition.

1. Right click on "my computer" icon and click "manage" on the context menu.
2. It will open the "computer management" window.
3. Select "Device Manager" in the left pane, It will list all the existing devices up.
4. Expand "Disc Drives" by clicking on the triangle in front of it.
5. Select one item under it, right click, uninstall.
6. Continue the process for all items under "Disc Drives"
7. Now restart the computer. At restart, windows will auto configure the appropriate system driver, msahci.sys.

Let us know the results.

I thought RST improve performance of hard disk? Never know it causes problems.

I am not sure if it increases performance or not, but many of them say it.

Personally, I have noticed a huge number of cases where RST is the sole problem. So I suggested it to you. And, none of your dumps indicating to it directly.

If you want to take it, I have nothing to say against you, but the driver is backdated, and I am sure that the latest drivers are even unstable.

leonnkeong said:

Uninstalling it will not cause any much performance problem right? From what you said, I should not update to the latest driver then?

Uninstalling it will not cause any problem at all. Coz, iAstor.sys fails, but msahci.sys never fails.

If you want to update RST, you may follow this post by Dave76. Here is a link, and Dave suggests that it is the most latest stable version. Whereas I always like to not keep it.

You may decide what you want to do. :)
