BSOD ntoskrnl.exe-7f1c0 while idling

Download and install Crystal Disk Info from here: CrystalDiskInfo - Software - Crystal Dew World
Watch and read the options when installing. There may be extras that you don't want installed through OpenCandy. Pay attention to the default check boxes and uncheck any extras. !!!!

Run the program and select the disk that contains your system files. Then expand the window (click and drag the bottom) so that all of the S.M.A.R.T. info is shown. Take a snipit of the window and post it.

It should look something like this:

Nothing unusual there except for the three power losses. Did any of these occur around the BSOD? I think the best thing to do is accumulate a few more dumps to try and identify a pattern. It may help eliminate the shotgun approach to debugging. Your memory checks out and your system files check out. There's not much left but motherboard and power supply. A few more dumps might help to narrow the search. In the mean time, check to make sure you have the most current BIOS (v10.5) for your motherboard. It should be available from MSI at the link below.

MSI Global ? Mainboard - Z77A-GD65

The crashes could be related to your out of date BIOS, as you say. Since you are running an SSD, that is the first thing you should probably check. Disable Verifier prior to flashing the BIOS; Verifier can cause crashes during a BIOS flash and any interruption of the BIOS flash will leave your system unable to function.


Your crashes primarily indicate 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, uninstall it in device manager and see if the system performs better.
  
  
  
• 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.
