*** ERROR: Module load completed but symbols could not be loaded for aswbidsdrivera.sys
*** ERROR: Module load completed but symbols could not be loaded for aswMonFlt.sys
Probably caused by : aswbidsdrivera.sys ( aswbidsdrivera+1971f )

aswbidsdrivera.sys dated 2/22/2018 Avast.

I would fully uninstall Avast and only use Windows Defender (which is what I do use on all my systems). After uninstall run the Avast Removal Tool to prevent trouble causing remnants.

Hi Mayur. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

Run a full disk check on all partitions: https://www.groovypost.com/howto/check-hard-dri...

If necessary run it from the Command Prompt from Repair Mode or booted media:
https://www.raymond.cc/blog/running-a-check-dis...
https://www.tenforums.com/tutorials/2294-advanc...

Once you do that if indicated then run bootable hard drive diagnostics to know for sure it's condition: http://blog.nowherelan.com/2013/04/04/boot-seat...


To create Windows 10 Installation Media install Media Creation Tool and follow the directions here: http://windows.microsoft.com/en-us/windows-10/m....

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key: https://www.sysnative.com/forums/hardware-tutor...

If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

Choose the boot device as a UEFI device if offered, on second screen choose Repair My Computer, then Advanced Troubleshoot Options to Command Prompt to run Disk Check, or Reset to reinstall Windows saving your files.

If all else fails choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, click Next to let it create needed partitions and start install - this makes it foolproof.

You will get and keep the best possible install to the exact extent you stick with the steps, tools and methods in the linked tutorial. It's a better install than any amount of money could buy and a great learning experience that will make you the master of your PC.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

The above was the Memory Dump however two of the minidumps were even more troubling. The 3rd dmp file was corrupt (042818-15890-01).

BugCheck EF, {ffffd98c1cd43240, 0, 0, 0}
ETW minidump data unavailable
Probably caused by : ntkrnlmp.exe ( nt!PspCatchCriticalBreak+ff )

BugCheck C000021A, {ffffba8473138290, ffffffffc0000428, 0, 14e8dc40000}
ETW minidump data unavailable
GetPointerFromAddress: unable to read from fffff802dfc80188
Probably caused by : ntkrnlmp.exe ( nt!NtSetSystemPowerState+b90

ntkrnlmp.exe is a Windows component which means something else drove it into fault.

Both of those are usually a hardware issue though they could also be caused by Avast (or any 3rd party antivirus that might be used).

If removing Avast does not help use the below methods :

1. Remove ALL power then reseat the cards, memory, and cables (on both ends when possible).

2. Run the memory tests (see methods below).

3. As needed use ALL the methods in the troubleshooters below.

4. After ALL the above if needed run Driver Verifier again to see if it can indicate a CAUSE.

Keep in mind that the odds are hardware is involved and you can't fix hardware with software.

This utility makes it easy to see which versions are loaded :

Run DriverView - set VIEW to Hide Microsoft drivers - update those without Dump in their names (and update BIOS and chipset drivers).

DriverView - Free - utility displays the list of all device drivers currently loaded on your system. For each driver in the list, additional useful information is displayed: load address of the driver, description, version, product name, company that created the driver, and more.
http://www.nirsoft.net/utils/driverview.html

For Drivers check System Maker as fallbacks and Device Maker's which are the most current. Right Click the Start Button - Device Manager - Display Adapter - write down the make and complete model of your video adapter - double click - Driver's tab - write down the version info. Now click UPdate Driver (this may not do anything as MS is far behind certifying drivers) - then Right Click - Uninstall - REBOOT this will refresh the driver stack.

Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party with their own software and drivers and any other major device drivers you have.

Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for BIOS, Chipset, and software updates at System Maker's site while there.)

Download - SAVE - go to where you put them - Right Click - RUN AS ADMIN - REBOOT after each installation.

Always check in Device Manager - Drivers tab to be sure the version you are installing actually shows up. This is because some drivers rollback before the latest is installed (sound drivers particularly do this) so install a driver - reboot - check to be sure it is installed and repeat as needed.

Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check manually by model.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

Memory tests do not catch all errors such as mismatched memory (possible even for sticks that appear to be identical) and when faster memory is placed in system behind slower memory. So it is best to also swap sticks in and out to check for those even if all memory tests fail to show a problem.

To test RAM check here - let it run 4+ hours or so. <-- best method

For the Windows Memory Diagnostic Tool.

Type in Cortana's search box -> Windows Memory Diagnostics
at top of list - click it. in Windows 8/8.1/10 the name is "Windows Memory
Diagnostic".

=====

After doing ALL the updates you can, and if the issue continues, then run
DriverVerifier.

Driver Verifier can help find some BSOD issues :

If DriverVerifier creates a minidump upload it and post the link here so we can analyze it.

After running the check disk that Greg suggested, try running these next two checks:

********************

After ChkDsk is done go back to the admin prompt and run following commands, one at a time to Repair The Installed Windows Image


this command performs Window repair operations automatically:

Dism /Online /Cleanup-Image /RestoreHealth

DISM creates a log file (%windir%/Logs/CBS/CBS.log) that captures any issues that the tool found or fixed. %windir% is the folder in which Windows is installed. For example, the %windir% folder is C:\Windows.

https://docs.microsoft.com/en-us/windows-hardwa...

*********************

https://support.microsoft.com/en-us/help/929833... - Process shown with pictures

In start menu type “PowerShell”

Right Click on the result and select “Run as Administrator”

Type (or paste) the following command and press <enter> to Scan the integrity of all protected system files and replace incorrect versions with correct Microsoft versions.

sfc /SCANNOW

**************************************

Though Rob has explained everything, but I think a disk check is neccessary.
Download and run HDTune .

Select the Disk where OS is installed.

Make screenshots of the following

the error scan
the benchmark
Post back the screenshots.
