Hi all–
I have the same problem as many others on this forum. My computer suddenly won’t reboot in any mode. When I try safe mode, the computer hangs on aswrvrt.sys and goes to the blue screen with the floral design and a low-res arrow.
Of course I don’t have a recovery disk.
It’s an Acer running Windows 7. I think it’s a 64-bit.
Help!
Thanks!
What happened prior to the non-booting ? I will PM the ISO links
Download the following three programmes to your desktop :
For 64bit systems
2. Windows 7 64bit RC
3. Farbar Recovery Scan Tool x64
For 32bit systems
2. Windows 7 RC
3. Farbar Recovery Scan Tool
Insert the USB stick Then run Rufus
https://dl.dropbox.com/u/73555776/RufusISO.JPG
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

When you reboot you will see this.

Press Scan button.
It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.
Thank you.
I honestly can’t remember what I was doing before I had to restart (it was a couple of days ago). I think the computer froze while I was switching screens, and I finally just turned it off and tried to reboot.
Ta gives me something to think on 
Here you go. FWIW, the process was really really slow. I had to wait for a very long time between each step. (Except the actual scan–that was super fast.)
OK as I suspected
Run the recovery console and get to the command prompt
At the command prompt type the following :
chkdsk c: /r
Once it has completed then boot to normal mode
Thank you.
While I am waiting for the program to get back to the command prompt, I have clarification question. Right now my screen says Windows 7 is on (D:) Local Disk. Should I run chkdsk on C or D?
Karen
Yes use D first
chkdsk d: /r
But be prepared to run c as well
Thank you for your patience.
I ran chkdsk on D, but it hung up at 11% complete and stayed that way for a couple of hours. I aborted and ran it again. It’s been hung up at 11% (again) for 20 minutes or so, though the number of files processed is higher than last time. Abort again and retry, or is there something else I should do?
Stage 4 of 5 both times.
Sounds very much like a hard drive problem I am afraid as your MFT was corrupted, hence chkdsk which should have cured that
Is it finding errors on the drive
I left it running all night. It was at the same place this morning, but has now advanced from 79993 to 144462.
“Windows replaced bad clusters in file 80011 of name \PROGRA~1\AVASTS~1\Avast\Setup\VPS_32~1.VPX.”
I guess I’ll leave it running for a while in hopes that it is fixing things, not stuck. And consider a new hard drive.
Really, a surface scan should be done, either utilizing chkdsk, or the manufacturers utility before
deciding the drive is bad. Those look like logical errors to me. Not hard (surface) errors, but errors where the
pointers in the file table and/or other parts critical to NTFS have been corrupted for one reason or another.
I’m beginning to wonder if avast itself, in certain circumstances, trashes the disk, because there have been so many
incidents. In some case, when essexboy has provided a script to “uninstall” avast using FRST, users
PC’s miraculously recover, and other times they do not.
Similar problem happened to me once before, the boot stops at a black screen and goes no further.,
usually on Windows Vista and newer systems.
THANK YOU.
CHKDSK finished, finally. I’ve restarted the computer, and it seems to be working.
Here’s what was displayed at the end, after 5 of 5 ran. Do you see any red flags?
I very much appreciate the help.

Nope that shows that it managed to fix the MFT
Any further problems ?
Not so far. Thanks again!
After the repair did you get your files back or was the computer the same as before it would not boot? Mine is acting up and I wanted to know because I getting ready to back up my files and do a restore from a old backup. I would like to try this method first so I don’t have to reload files to get mine back. Please understand my computer is only locking up but I figure it will go away if this keeps up.
As far as I can tell, it’s as good as new. I don’t think I lost anything.
Thank you. This maybe the way I try should things get worse with my computer.
