Windows 7 OS Bluescreen Crash at Startup -

Xterron · May 3, 2015

I recently went to turn on my pc and just as the Windows OS starts to load, my computer crashes with a very quick blue screen flash and restart. This repeats itself over and over again. It referred me to Startup Repair which was no help. I am not even able to get into Safemode without the same result, however I do see that during a Safemode attempt the last file to load is "ASWRVRT" before it crashes. I was able to go into DOS and run chkdsk /f with no issues displayed. I also ran sfc / scannow and no integrity errors. (I had to get creative to run scannow as my pc kept saying I had a repair that required a restart which never clears this message despite countless restarts). I have added no new programs or peripherals to my system. I did notice though that when I went to try a system restore, the last 2 restore points were from a critical Windows update and Avast Security update. I tried using these restore points as well as earlier ones and kept getting "unspecified error: 0x80070005" with failed restores. I have seen many threads with this same exact issue, however none seem to offer a resolve. This same issue seems to have occurred to at least a handful of others with the same crash error message:

STOP: 0x0000007b
(0xFFFFF880009A97E8, 0xFFFFFFFFC00000034, 0x0000000000000000000, 0x0000000000000000000)

Can anyone offer a solution, please? These support forums are a proven lifesaver and I would really prefer not to have to reload a clean OS.

My system is a desktop built by an IT friend in 2013 and I have had no issues with the Bluescreen until now. I am running Windows Home Premium X64. Thanks for reading and any reply!

Open BIOS screen (usually clicking ESC and go to setup or DEL, depending on the BIOS)
Location SATA setting. It should show you AHCI (Advanced Host Controller Interface) or RAID. Kindly change it to IDE.
Reboot. It should reboot fine without hiccups. If you still experience difficulty in booting, then this is not the solution.
Now open Registry Editor (click Windows key - R and then type in regedit and press enter)
Locate this entry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci. Look for the DWORD “Start” and double click and change its value to 0 (zero)
Do the same with this entry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\pciide. Look for the DWORD “Start” and double click and change its value to 0 (zero)
If you are using RAID, do this too: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStorV
Close Registry Editor and reboot your computer.
On booting process, open BIOS again (see step 1)
Now locate SATA setting and kindly change it back to AHCI or RAID.
Save settings and let it reboot. It should work perfectly fine with one difference, when you enter the Windows screen, they will start installing new drivers and will ask you to reboot. Let it reboot one more time.

Voila, problem solved! And you are back with AHCI/RAID setting again. Basically the problem is something went wrong and it was loading the wrong driver.

ASWRVRT= Avast! Revert driver

error code:
0xc0000034 (3221225524) - Object Name not found.
0x7b (123) - The filename, directory name, or volume label syntax is incorrect

check in BIOS about your SATA mode for your hard drive. Maybe it got changed if you updated or cleared the BIOS to defaults. Otherwise I would be talking to the support at
Avast to get their product uninstalled/reinstalled
