    Windows 7 OS Bluescreen Crash at Startup


    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 7 Home Premium X64. Thanks for reading and any reply!

    I apologize as when I check Debug screen in DOS, it appears I didn't have the PC programmed to generate a dump file as it says "0". I have no idea where to check using DOS commands (as this is all I have right now) to find and save a copy. Any suggestions?

    Stop 0x7B does not allow the user to boot to the desktop.

    Hi Xterron. Can you boot to windows anyway, even in safe mode? If so, Follow what Layback Bear suggested.

    If the computer still shows this BSOD when you power it up, do three things.

    ► Scan the system for possible virus infection with a bootable antivirus.


    ► Test the HDD with a bootable disc check tool.


    ► Do you have access to another computer right now? If so, download Partition wizard Bootable CD (the last one in the link). Burn it in a blank CD or in a USB flash stick.

    Boot into Partition Wizards GUI following this instructions. When you are on the last screen, take a camera snap of the screen and upload the snap here.

    We need to see the partitions and parameters.

    After knowing these results (at least the result of seatools test. If there is no error, the easiest fix is a clean reinstall) we can guide you towards the solution of the issue.
