What is wrong with this actually(Blue Screen)?

Yes. It appears you are still having the same problem you were having in that thread. We would also still prefer if your system specs were in your profile and not in a post in another thread or in this thread. That way, if you start other threads later, you do not have to keep linking back to your old threads and have us try to find the post that contains the information. Many of us are helping in anywhere from tens to hundreds of threads, so having to get your info each time takes away from our ability to help others. By putting your specs in your profile information, you are being respectful to those helping and also to other users getting help on the forums.

The Intel driver you want is the very bottom one.

Code:

VGA Driver	Intel	8.15.10.1968	51.0 MB	01/13/2012

You can upload the system specs in Internet Explorer if you use that browser. If you use a different browser, you will need to enter it by hand. The application makes it easier to get the information in a clear manner.

There is a difference if you do not uninstall the older drivers before installing the new drivers. If the old drivers were corrupted, remnants of the corrupted files can still exist with the new install, so installing over them does not remove the corrupted files. Uninstalling first removes the corrupted files so the updated drivers can be installed fresh with no old files remaining.

Let us know how the system is responding after you have more time to do your normal routine.

Is the system still under warranty?

If there is something wrong with the graphics card, that would indicate there is something wrong with the motherboard. It would be good to know if the system is under warranty.

Any new .dmps?

That BugCheck indicates hard disk problems. This could mean hard disk corruption, bad sectors, a failing hard disk, Windows files or registry corruption, viruses, or memory problems.

• If you are overclocking any hardware, please stop.
  
  
• Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs. Post back your logs for the checks after finding them using Check Disk (chkdsk) - Read Event Viewer Log (you may need to search for wininit instead of chkdsk).
  For any drives that do not give the message:
  Windows has checked the file system and found no problems
  run disk check again as above. In other words, if it says:
  Windows has made corrections to the file system
  after running the disk check, run the disk check again.
  
  
• Run the short and long tests with SeaTools for HDDs.
  SeaTools for Windows
  
  SeaTools for DOS
  
  
• If you have an SSD, make sure the following are up to date:
  • SSD firmware
  • BIOS Version
  • Chipset Drivers
  • Hard disk controller drivers/SATA drivers
  • If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.
  
  
  
• Check Windows for corruption. Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.
  
  
• Download and install Malwarebytes, update it, do not start the free trial, and then run a full scan. Also run a full scan with your antivirus software installed on your system. If you do not have antivirus software installed, see the Good and Free system security combination. for better security steps and scanning tools. Make sure to update the security software before running the full scan.
  
  
• Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
  
     Warning

  Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!
  
  For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
  
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
  
  Once these steps have been followed, it is safe to remove and replace components within your computer.

I have a question here. If i were to format drive and reinstall Windows(from recovery disks). Will it solve this problem for sure?

If it is software based, it probably will. Depends one whether you install the same software and drivers again, though. It could still be a software or driver conflict that is causing issues. We should first rule out hard disk corruption and errors first, though.
