Custom dynamic link libraries are being loaded for every application. The system administrator should review the list of libraries to ensure they are related to trusted applications.

Which antivirus do you use? Please uninstall it, at least as a test. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

Scan the system for possible virus infection with the following programs, too.

• Anti-rootkit utility TDSSKiller
• Windows Defender Offline

Let us know the results.

I will also go with what Greg suggested. And, let us know how you uninstalled Intel Rapid Storage?

The storage are set to AHCI mode, the controller is msahci.sys, but iastor (which had been a great problem a month ago) is still left over there.

Code:

iastor    Intel AHCI Controller    c:\windows\system32\drivers\iastor.sys    Kernel Driver    Yes    Boot    Running    OK    Normal    No    Yes
iastora    iaStorA    c:\windows\system32\drivers\iastora.sys    Kernel Driver    Yes    Boot    Running    OK    Normal    No    Yes
iastorf    iaStorF    c:\windows\system32\drivers\iastorf.sys    Kernel Driver    Yes    Boot    Running    OK    Normal    No    Yes
iastorv    Intel RAID Controller Windows 7    c:\windows\system32\drivers\iastorv.sys    Kernel Driver    No    Manual    Stopped    OK    Normal    No    No

On the contrary, the storage controller is msahci.

Code:

Name    Standard AHCI 1.0 Serial ATA Controller
Driver    c:\windows\system32\drivers\msahci.sys (6.1.7601.17514, 30.38 KB (31,104 bytes), 11/08/2013 10:56 PM)

Intel storage drivers have been a great problem here.

I would suggest a Clean Reinstall - Factory OEM Windows 7 without intel rapid storage technology.

Was the uninstall not clean?

No, it is not, and that is why I asked it in my earlier post ....

Code:

let us know how you uninstalled Intel Rapid Storage?

Leftovers are there, and active.
At that time, as it is uninstalled, I am not sure seeing that data that how iastor.sys was working there in the system ... SCSI or AHCI. And so I cannot say you the exact steps what should be taken now.

So it would be better to start afresh.
