Windows 7: Random BSOD's, Mostly caused by ntoskrnl.exe

Random BSOD's, Mostly caused by ntoskrnl.exe

Hi, i'm receiving random BSOD's for a long time. I want to fix it but i don't know much about it, so sorry if it isn't the good information. According to BlueScreenView, it's mostly the ntoskrnl.exe, but there are also messages about AsrOcDrv.sys, nvlddmkm.exe and ntfs.exe. I just did wat the BSOD posting guide said so hopefully it's enough.

    please go to start and type in "msinfo32.exe" (without the quotes) and press enter> save the report as an .nfo file, then zip up the .nfo file and upload/attach the .zip file with your next post.
    • also, save a copy as a .txt file and include it also (it's much more difficult to read, but we have greater success in getting the info from it).

Based on the bugchecks, I would recommend you follow and complete the steps given below:
1. If you are overclocking any hardware, please stop. Reset any changed values back to default and reset/clear CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS. Uninstall any overclocking tool as these can also be a reason of blue screens.

2. Uninstall your current antivirus software. It can be a cause of BSOD very often. Please remove it with its removal tool and use Microsoft Security Essentials in its place. Malwarebytes is a great combination with it. Go through this thread for more info.

3. Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors. Post back your logs for the checks after finding them using Check Disk (chkdsk) - Read Event Viewer Log

4. Run SFC /SCANNOW Command - System File Checker to check windows for integrity violations. Run it up to three times to fix all errors. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations.

5. Make scans with Kaspersky TDSskiller and ESET Online scanner.

6. Perform a Clean Start up, this will help avoid any problematic applications from bugging the system.

7. Use Revo Uninstaller Free to uninstall stubborn software. Opt for Advanced Mode and uninstall the software, delete the leftover registry entries.

8. Use Crystal Disk Info to upload a screenshot of your Hard Drives (s). Test your Hard Drives (s) running a Hard Drive Diag.

9. Test and Diagnose RAM issues with RAM - Test with Memtest86+. Pay close attention to Part 3 of the tutorial "If you have errors" Take the test for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.

10. Monitor hardware temperature for overheating issues with system monitoring software like Speccy or HWMonitor. Upload a screen shot of the Summary tab as well:
