This is odd. Try running SFC /scannow from an elevated command prompt. Report back any console messages.
Also check to see if there are updates for drivers and the BIOS from Dell.

Forgot to ask- Are you trying to run RAID on a single drive?

Scan your system with the following:

• Kaspersky TDSSKiller
  
  • How to remove malware belonging to the family Rootkit.Win32.TDSS (aka Tidserv, TDSServ, Alureon)

• ESET online scanner
  
  • One-time virus scanner free with ESET online scanner

Code:

Start Menu\Programs\McAfee	Public:Start Menu\Programs\McAfee	Public

McAfee is a frequent cause of BSOD's. As a test please remove it using the McAfee Removal Tool from here: Uninstallers (removal tools) for common antivirus software - ESET Knowledgebase

We recommended Microsoft Security Essentials from a strict BSOD perspective. Is most compatible & provides best stability compared to other antivirus app/Internet Security Software.

• Microsoft Security Essentials, Free antivirus for windows
• Malwarebytes Anti-Malware Free
• Good and Free system security combination

   Warning

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Run a full scan with both (separately) once downloaded, installed and updated.

Number down items at start-up. Keep only your anti-virus, this also improves the time for logging into windows.

• Click on the Start button
• Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
• Select the “Startup” tab.
• Deselect all items other than the antivirus.
• Apply > OK
• Accept then restart.

• Troubleshoot Application Conflicts by Performing a Clean Startup

Use the System File Checker tool (SFC.exe) to determine which file is causing the issue, and then replace the file.

To do this, follow these steps:

1. Open an elevated command prompt. To do this, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
2. At the command prompt, type the following command, and then press ENTER: sfc /scannow
   The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.

SFC /SCANNOW Command - System File Checker

Check your hard drive(s) for errors by running chkdsk:

• Check your hard disk for errors
• Disk Check

Let us know the results and further BSOD reports if you have them.

Thanks for stepping in on my absence Yussi. Don't you ever sleep? :)

Tamilzu- Iastor.sys is an Intel driver for the Intel series of chip sets used for disk drive controllers. It's used by many OEM manufactures. I use it myself on the system I'm using now. That's not to say there could be malware called by the same name. Follow the AV scan directions above and keep us posted.

Yes I do. For 6 hours max :)

It's just that we're online at the same time

Apologies for my late reply i was out of town due to an officialtrip.
I followed all the steps excepts chkdsk as i get 'check disk cancelled 'error while rebooting. attaching the latest dump. Nothing unusual detected in other steps.

Please advice

Do you get BSOD in safe mode?

The Intel drivers still aren't matching up. Also, I'm seeing an Adaptec AHCI driver. Do you have an Adaptec adapter card installed in your system?
