Blue screen errors D1 and 7E Iastor.sys!!! Help

I`m having a blue screen error with the D1 code , iastorA.sys
It started with the E7 code iastory.sys error then the D1 .
My laptop information is :
Windows 7 pro
Intel core i5-3317 1.70 Ghz
RAM : 6 GB

My actions:
I checked the memory and it should be fine.
I format and install new windows 7 Pro.
I used the Symantec removal tool.
I update the Intel RAID Controller driver and that elminate the 7E BSOD, still the D1 alive though!
Checkup disk and defgramentation are done.
The BS C also happend when running in safemode
The D1 error came alive when I install a driver for SM controller, when uninstalling it , it back to the e7 code error
