Intel RST Service not running in Windows 7 Home Premium 64 Bit  

I have refreshed my Hard disk in Acer Aspire Laptop and restored the windows using the recovery disk. After the restore, Inter RST displays a yellow triangle and says the "RST services is not Running". When I try opening the RST, I get a message 'IAStorUI has stopped working'. Also the performance of the PC has reduced after the HDD refresh. The Local Services shows that 'Inter RST has started'.
Please help in resolving the issues.

Under the Services tab, I see Intel RST status as running. My Laptop model is Acer Aspire 4738G.

Hi Maxie, My laptop has the latest updates installed from Windows. From the link which you have provided, I searched the model number and found a list of drivers. But I was unable to find the Inter RST driver.
Sorry to ask you, can please let me know the drivers i'm supposed to install.

When i tried installing the SATA ACHI driver, I get the error message 'This computer Does not meet the minimum requirements for installing the Software". I have attached the screen shot of the error

My windows is up to date. I have installed all the latest updates from Microsoft..
