Windows 7: AutoFailover

AutoFailover

So for the past day or two, I've encountered some serious issues with my desktop.


First problems were BSOD - giving the error "IRQL Not Less or Equal". These would happen sporadically and I could never pinpoint the cause of the BSOD. I am able to access the minidump files if needed. Sometimes I could go several weeks without a BSOD and sometimes I'd have several in one day.

I updated drivers for video card and NIC and after about a little over a week of no BSODs, this occurs...


My screen flickered and I heard a click from my tower and I lost my second monitor (just went blank). I was in a program at the time of crash. I'm not able to say what the program was due to it being a pre-beta release and I'm bound by the NDA. I wasn't able to ctrl+alt+delete - had to perform a hard reset.



I couldn't even boot into Windows -it took me to the StartUp Repair and tried to run through its self-correcting tool but wasn't able to fix any problems. It then gave me the option of running a restore (I had no restore options), command prompt, etc or shut down or restart.

Here's what I've done so far -

Downloaded a copy of Windows PE on another computer and burned the .iso onto a dvd. Used that to boot into PE and remove the nvscv64.dll file from the Windows\System32 folder and placed it in a new folder on the desktop.

Removed PE dvd from drive and rebooted computer - Windows failed to load again. Tried another reboot and the bios failed to recognize the keyboard. Tried 3 more times to reboot but got stuck at the BIOS with the keyboard failure - tried using two different keyboards: A Logitech G15 and a generic Dell keyboard I found lying around.

Tried rotating USB ports - still not recognized

Reset the BIOS using jumper pin on mobo - now gives me CMOS checksum error - Defaults loaded.






Here's the full work up:

Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: 21200800
Problem Signature 05: AutoFailover
Problem Signature 06: 4
Problem Signature 07: NoRootCause
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033







After letting the computer sit for a while I was able to finally get past the POST screen. I was then able to go back into Windows PE (XP edition).


I moved all of my Nvidia drivers to a new folder through Windows PE - tried booting up again and I still get a strange setup on my POST screen - green dots everywhere! But it's ordered patterns of green dots/pixels. And of course, Windows screen loads and then fails tries StartUp repair and reboots.


So, today I went to Worst Buy and bought a new video card (Nvidia 560GTX Ti) - This time I get no crazy green dots all over my screen and I can select the boot menu. I try going for my regular hard drive (I have 4 in my computer right now - I don't know why) but it kicks me back to the Startup Repair screen which fails and reboots itself.


I let it reboot and then select the boot menu again and choose the same hard drive. But this time, I select "Windows 7 (recovered)" - the third option.


My choices at the boot menu are:
Windows 7
Windows 7 (recovered)
Windows 7 (recovered) - this is the one I go with


So, after selecting the third option - I can actually get to my login screen for Windows - I enter my password but it's running off of an old hard drive with a Windows installation.



So, right now, I do have functionality with my desktop but it's not running off the hard drive I want it to. My regular C: drive has now been pushed down to H:


I'm dreading having to reinstall a copy of Windows on my preferred hard drive. But right now, I can't get past the Startup Repair.


Any suggestions?

Check for malware first. Download this;

Malwarebytes

and run a FULL scan. If it finds anything post the log here.

I'll give the Malwarebytes a try - but I've already ran SuperAntiSpyware and AVG in safemode during the BSOD phase and found nothing more than tracking cookies.

In that case it sounds like a hardware problem, most likely caused by overheating. Any obvious correlation to ambient temperatures you can think of?

The fact that it comes back after sitting for a while would tend to strengthen that hypothesis.

Otherwise I have nothing useful to contribute at the moment.

Hmm... I've never had heating issues in the past. My CPU temp typically hovers between 37 and 41 degrees Celcius. I have an Antec Server Tower that stands a little over two feet tall - and I have plenty of good airflow.

I've backed up my important files and I think I'm just gonna go with a fresh install.
