Windows 7: BSOD nvstor.sys DRIVER_IRQL_NOT_LESS_OR_EQUAL


14 Oct 2011   #1

Windows 7 64-Bit
 
 
BSOD nvstor.sys DRIVER_IRQL_NOT_LESS_OR_EQUAL

I'm getting this BSOD on Windows 7 Ultimate 32-Bit. I kept getting them when I was casually using my computer, so I started using Windows XP Professional 32-Bit because it was on my 2nd partition, and it works perfectly.

So what I did was I pressed F8 on Windows 7 for more options and I did "driver restore" something like that, I can't fully remember. I also tried chkdsk, and it found nothing. Lastly, I tried Memory Diagnostics, and Windows found nothing wrong with my RAM. I also tried another RAM checker but I forgot the name, however it seemed to be recommended by a lot of people.. and it found nothing wrong as well.

Specs:
4GB RAM - 2GB RAM came with my computer, and I bought an extra 2 myself.
nVidia GTS 450 [Graphics Card]
AMD Athlon™ 64 X2 Dual-Core Processor 5000+

Rest of specs can be located here:

Motherboard Specifications:
Motherboard Specifications, MCP61PM-HM (Nettle2) HP Pavilion a6200n Desktop PC - HP Customer Care (United States - English)

I backed up all of my files on a USB Drive, and tried to install a fresh copy of Windows 7 Ultimate (64 Bit) because I found out my computer is 64 Bit, however I have been using 32 Bit this whole time because I didn't know (my computer is both 32/64 bit compatible) however, that just freezes at Expanding Files.. 0%. So I tried to install Windows 7 x86, and it freezes on Expanding Files.. 0% as well. So I kept trying, and it finally got to 18% ONCE. Then it froze, I tried again and it gave me the nvstor.sys DRIVER_IRQL_NOT_LESS_OR_EQUAL BSoD.

I've googled a lot and can't find anything that will help me fix it, also here is a new problem.. Windows 7 boots up on Start up Repair and I can't do advanced options (F8) so I'm stuck on Windows XP.

I tried to get minidump files for you guys, but C:\Windows appears to have no minidump folder.
Here's a screenshot:

We do need the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.


To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.

Windows 7 64-Bit
 
 

The problem is that I can't boot into Windows 7, after the BSoD during the attempted windows 7 installation, it boots into start up repair (which doesn't find anything wrong) and tells me if I want to send Microsoft an error report. It finds nothing wrong..

C:\Windows\Minidump is not there. I'm guessing it's not enabled, I wish I could enable it but as stated above I'm stuck.

It was working yesterday, except for the random freezes that is probably caused by the nvstor.sys file.

Can you boot into safe mode (F8)?

Well, the actual problem is that I tried to install Windows 7 over the Windows 7 partition, and it froze at Expanding Files 18%.. and I guess it deleted my user profile and necessary system files =[
