Win7 won't boot after updates, aswrvrt.sys driver broken?
« on: June 29, 2015, 09:40:00 PM »
Hello,

The other day i applied a bunch of windows updates to my PC (don't remember which, i hadn't been updating in a while).
Everything looked ok, but when i tried to turn the pc on the following morning, Win7 stopped booting. It just hangs on the windows logo and never moves from there.

I tried booting in safe mode and noticed the same thing happens and Win7 stops loading when it reaches driver aswrvrt.sys.
After some research i gathered that this is something avast-related..can anyone help me?
What should i provide to make it easier to troubleshoot the issue?

On a side note: i tried a system restore to the day the updates were installed, but it was no help.

Thanks.

Download the following three programmes to your desktop :
 
 
1.  Rufus 
 
For 64bit systems  
2. Windows 7 64bit RC link will be sent by PM
3. Farbar Recovery Scan Tool x64 
 
Insert the USB stick Then run Rufus
 

Select the ISO file on the desktop via the ISO icon. 
 
Press Start Burn

Then copy FRST to the same USB   
 
   
 
 
 
Insert the USB into the sick computer and start the computer.  First ensuring that the system is set to boot from USB 
Note: If you are not sure how to do that follow the instructions Here
 
Windows 7 and Vista screenshots 

When you reboot you will  see this.
 Click repair my computer  
 
 
Select your operating system  
 
 
Select Command prompt 
 
 
At the command prompt type the following  :
 
notepad and press Enter
The notepad opens. Under File menu select Open
Select "Computer" and find your flash drive letter and close the notepad. 
In the command window type e:\frst64.exe  or  e:\frst.exe dependant on system
 and press Enter 
Note: Replace letter e with the drive letter of your flash drive. 
The tool will start to run. 
When the tool opens click Yes to disclaimer. 

Press Scan button. 
It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.

Hello,

How long should FRST take to launch? I downloaded the 64 bit version as my OS, but whenever i launch it it never starts. Checking with the task manager it's stuck on not responding.

It should start straight away. 

Are you running it from the recovery USB ?

I made the mistake of trying again but not being fast enough with the boot selection, and for some reason there was a disk check scheduled for the C drive which i wasn't able to skip no matter how much i pressed 'any' key.
It's slowly advancing and finding a shitload of errors, which surely doesn't make me happy.
I'll be back once it's completed, and try again to get the log from FRST.

Thanks for your support in the meantime :)

If a dskchk has been generated then that may be the problem.  Try a normal boot initially after it has finished

Still there scanning, i'll let it go through the day.

How bad would it be if i stopped it? If it keeps up with this speed it'll take weeks

Sounds very much like a major hard drive problem, you can try to stop it but you may enter a loop

I agree....especially depending on the errors/fixes you are getting....bad sectors ? file system corruption ?
I'd let it finish no matter how long it takes and hopefully you can boot.
If not, perhaps the FRST log will allow Essexboy to tweak and get to boot.

If it does boot then you should consider a HDD replacement.....find a util to check the integrity of the HDD.
Your BIOS or PC may already have one but here is one from SeaGate: http://www.seagate.com/support/downloads/item/seatools-win-master/
How To Use SeaGate HDD Tools: http://knowledge.seagate.com/articles/en_US/FAQ/202435en

At min do an in-place upgrade (reloads O/S cleanly) of W7....does not hurt your data/program installs.
Here is link on procedure but unlike XP you have to have W7 up and running.

If you don't have a Retail W7 O/s disk here is link to ISO.

Alright, here's the situation after yesterday: i came home to a windows login screen. Everything appeared to be working, i was able to log in and the pc looked ok.
I turned the pc off and went to bed. Now i'm back from work and i turned the pc on again and again it's going through the checkdisk, and again it's moving very slowly (it's at 6% now and it started again with the "File record segment x is unreadable". I'm wondering if this was caused by the system restore, as nothing of this happened before i tried that.
I'll wait some more and see if it completes the check again and if it does, if it gets me to the login screen again.

If that happens i'll try the HDD integrity utils and the OS reload.
The disk itself is only a few months old, it didn't got hit or anything so i hope there's no HW failure incoming. If i lose those 3tb of data i'm going to be very, very sad, lol.

I'll keep you posted. Thank you very much for the help :)

Once this chkdsk has finished and you get into windows
Run an elevated command prompt to stop any loop that is currently set by using the following command :

chkntfs /x c:
