Windows 7: BSOD 0xc0000001 0x00100950

16 Oct 2012   #21

Windows 7 Home Premium (x64) (build 7600)
Update - All is Not Well

The beeping I'm talking about refers to a series of beeps usually before a crash. Last night I shut down my system and this morning it took about 30 reboots before it fully started. First it stopped at the dell window, then at Starting Windows, then at Starting Windows with the logo.

Yesterday I made a bootable copy of the Win 7 64-bit Home Premium iso 58997 (from Digital River) using the Win & USB DVD Download tool. I'm backing up everything right now. I also have a repair disk made from this system.

Can you think of any additional diagnostics to perform? What would suggest as next steps? Can we rule out the hardware before I wipe the drive and reinstall - although that's an appealing option at this point.

Once again, thanks so much for all your help!

Please accept my apology for jumping in. The beeping could be a sign of a failing motherboard. Especially in light of the numerous reboots. You'll need to know the manufacturer of the motherboard because each manufacturer uses different beep codes. It might be hard to do if you can't boot the system because you'll most likely need to install some software to read your computer's hardware. Many folks recommend a free product called Speccy.

Once you know the manufacturer this list of beep codes may help figure out what's going on.

Windows 7 Home Premium (x64) (build 7600)
Full MSE Scan Results

I've attached a screenshot - apparently I had three vulnerabilities that had been installed with Java. Here's the Oracle info -

Alert for CVE-2012-4681

So that's now ruled out. I'm hoping that my motherboard doesn't have to be replaced - this was an $1800 system 4 years ago that was completely replaced by Dell 2 years ago with a different model - after complaining the the Better Business Bureau.

Thanks again all!

Still Having Problems - System Hangs During RStartup

These error message are from the event log:

12:11 AM The shadow copies of volume C: were aborted because of an IO failure on volume C:.

7:35 AM The previous system shutdown at 12:45:59 AM on ‎10/‎17/‎2012 was unexpected.

System got to Resuming Windows and hung

7:34 AM The system was shut down due to a critical thermal event.
Shutdown Time = ‎2012‎-‎10‎-‎17T11:34:00.086025600Z
ACPI Thermal Zone = ACPI\ThermalZone\TZ01
_CRT = 358K (yes - this log entry is 1 minute earlier even though it appears later in the System log)

7:34:11 The LoadUserProfile call failed with the following error:
The media is write protected.

Then there are about 50 messages that are about services failing to start due to media being write protected or due to a dependency failure.

I haven't gotten a BSOD in a while. Any thoughts?

Thanks again!

One of the Forum experts prepared a couple of troubleshooting tutorials that may help sort all of this out. They are time consuming. But they've also helped many people figure out their computer problems (both software and hardware.)

Troubleshooting Windows 7 Failure to Boot

Troubleshooting Steps for Windows 7

My concern right now is even if you did a clean install, if this turns out to be a hardware issue, the problem(s) will most likely return. Considering how many days you've already invested, a couple more probably won't hurt too much to see if the underlying issues can be found.

Windows 7 Home Premium (x64) (build 7600)
New Issue - Catalyst Control Center No Longer Opens

This used to work prior to my updating the driver for my graphics card. I see the process in the Task Manager for a moment - ccc.exe - and then it disappears.

Any thoughts?

I will definitely review the tutorials you've cited. I just don't see how a hardware error could be so intermittent. I think that when I do a restart all is file. It's when the system goes to sleep the problem occurs.

Thanks again for your help!

Some Additional Info

Hi there.

I've started going through the troubleshooting suggestions in the link you provided and came across this info under Performance Issues and Tools - see attached screenshots.

I've lowered the resolution on my attached flat-screen to the recommended 1280 x 720.

Any suggestions based on this new info? Thanks again.

x64 (6.3.9600) Win8.1 Pro & soon dual boot x64 (6.1.7601) Win7_SP1 HomePrem

I'd like to offer a few suggestions and then get out of the way.

As you're going through the tutorials, note what you observe - as you did above. The two USB Mass Storage drivers are slowing down your system. It is reported as slowing down sleep/hibernation time. The time these two devices add are about 2 1/2inutes - that's forever! So I would read the event details and disable those two drivers.

I would also disconnect any external devices and evaluate the system. BSODs are natures way of protecting the system - usually hardware related, although software accessing the hardware can also cause problems. Eliminate the easy things first, then dig deeper with dumps if the problem continues.

I sometimes forget to mention that an up-to-date system runs better.
Windows Update and current Drivers from the manufacturer is my prescription. I don't trust so-called Driver Download sites and I've had mixed results with Windows Driver updates. Sometimes though the only place to get a Windows 7 driver is from WHQL.

You mention sleep a number of times. i.e. no BSOD for a while, then the machine sleeps and BSOD.
suggest turning off hibernation and running MSE scan again.

Command Prompt - run as administrator
powercfg -h off

Ok, good luck folks. I won't be of much more help in BSOD matters.

I might be a little more help....

Dell Studio XPS 1645 drivers site.

There is an Urgent Bios update A06, dated 02/02/2010. You might consider checking the Bios version on your machine. Don't update it yet - just check it and report it.
Edit: there's also A13 dated 04/07/11

Koolkat and Marsmimar are running this issue. I'm just applying what I already know to what I learn about particular issues - termperature sensors and system response.
