One day, after creating a Linux bootable USB, I noticed that at start up I got an error message from avastui.exe "The application was unable to start correctly (0xc0000005) Click Ok to close the application."

The creation of the bootable USB might have had nothing to do with it and was probably just a coincidence.

To fix the issue, I reinstalled Avast.

Later when I tried to install mirc, I got an error message that it could not complete the installation. I thought "hmm weird"...and restarted the computer.

At the "Windows starting" screen, it went back to restart, showing me the recovery menu screen.

I selected safe mode but it would still not start...but rather again restart and go back to the recovery menu.

I noticed during the drivers load list when attempting to start at safe mode, it stopped at \windows\system32\drivers\Aswardisk.sys before restarting (boot loop).

Another thing to note (in case this piece of info has any relevance) is a momentary, split second flicker of BSOD right after the Windows starting screen before proceeding to restart.

Things I've tried to remedy this issue:

  1. Last known configuration (advanced).

  2. Startup repair through Windows 7 installation disc. (No restore points so couldn't do that).

  3. Booted through Linux live USB and deleted the Avast folder in programs folder.

  4. chkdsk: c: /f /r. Result shows 0 KB in bad sectors.

  5. Renamed aswardisk.sys to aswardisk.sysa.
    Upon doing so, the drivers load list passed aswardisk.sys but then got stuck on another driver - aswbidsh.sys. So i did the same with that file. Again, it passed that file, but got stuck on another file called aswbuniv.sys.

    I continued this procedure with 2 more avast files - aswRvrt.sys and aswVmm.sys. But then it started to get stuck on non-Avast files, such as disk.sys and subsequently classpnp.sys. When I reached a file called fvevol.sys, renaming it did not result in safe mode passing/skipping the file like it did with the others, but rather go to a Windows Boot Manager screen like the 2nd screenshot here.

  6. sfc /scannow /offbootdir=d:\ /offwindir=d:\windows. Result says "Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.log windir\Logs\CBS\CBS.log."

None of the above methods changed anything, obviously.

Could someone PLEASE help? Needless to say, I don't want to do a clean install because I need my files. Nor can I do a backup because I don't have a 2TB disk atm.

Thank you so much!

Examination of CBS.log shows a problem with Windows Update. Below are some steps you can do, but before starting take very good backups of your data, perhaps up to taking a backup image of the disk.

Step 1 : Check Windows

From a Command Prompt (cmd) run as administrator enter the following commands:

sfc /scannow
dism /online /cleanup-image /restorehealth           (Windows 10 only)
sfc /scannow

Step 2 : Reinitialize Windows Update downloads

Enter the following commands:

sc config wuauserv start= disabled
sc stop wuauserv
ren %windir%\softwaredistribution softwaredistribution.old
sc config wuauserv start= auto
sc start wuauserv

Step 3 : Repeat

Repeat the above steps a couple of times, rebooting before each one. Sometimes this works where one run didn't.

Step 4 : Upgrade Windows to itself

Using a Windows 7 installation disc of the same Service Pack level as yours, reinstall Windows, letting it upgrade itself. If the installation does not find the existing Windows on disk, this step has failed.

Step 5 : Reinstall Windows from scratch

This is the last option, born out of desperation. While installing, use the opportunity to re-format the hard disk in the non-quick way, to renew any failing magnetism on the disk and to better detect bad sectors. This will take longer but will give better results.
