Hi, I just built a new PC (see specs on my profile) and installed Windows 7 Ultimate 64-bit. I have now had 4 BSOD in the first week since the Windows 7 install and PC build. It looks like the first one was related to the drivers for my Logitech Quickcam Pro 5000 which I learned is not supported for Windows 7. I installed the Logitech lws110_x64.exe anyway to see if that would work and it did to some degree. I was able to use the webcam with Skype successfully but with some color issues.

The first BSOD also occurred before I had installed the ASUS drivers that came with the motherboard as well as the Radeon 4770 drivers. In addition I updated the firmware on the Crucial 64GB SSD drive that I use as the boot partition where Windows is installed.

The next 3 BSOD were all indicating disk.sys so I am a little concerned and don't know what could be wrong.

I have since uninstalled the Logitech drivers, but I'm just not sure what could be the root of the problem. Attached is a zip file with the 4 .dmp files and also corresponding text files containing the debug analysis.

Any and all help is greatly appreciated!

these were caused by disk.sys.
I would run a system file check
type cmd in search>right click and and run as admin> sfc /scannow
update the old drivers

If you are over clocking STOP


let us know the results as you may need to run it again

good luck

Ken

Thanks for the quick response Ken. I ran the scan and the result was:

"Windows Resource Protection did not find any integrity violations."

I definitely do not overclock and have not tried nor intend to do so. I haven't found anything indicating that the drivers are old.

Any more suggestions?

I should note that I also detached the webcam from the PC in case that could be an issue. One thing that may also be notable is that following the first BSOD after I installed all of the drivers things were running smooth for about 6 days until yesterday when my wife came home and found the PC was off. Turns out that my electrical meter was replaced by ComEd so there was a power outage. Upon rebooting the BSOD info was displayed and then a few hours later another BSOD occurred. After that I did a shutdown and restart and the startup took a long time compared to the usual 10 seconds it takes (it's fast with an SSD). After that all seemed fine again until tonight when it happened again while Pandora was streaming through Firefox.

Thanks,
jb

Just updated the BIOS on my Asus P7P55D motherboard to the latest version. Hoping this helps. I haven't had a BSOD since yesterday evening.

I had another BSOD this morning unfortunately, so it appears BIOS update did not help. One thing I noticed when I assembled the PC was that as I attached the PSU to the motherboard that the ASUS manual says that they recommend that the PSU provides a minimum of 600W. The PSU that I use is 500W. Is it possible that this is my problem? Below is the analysis:

It looks like the first one was related to the drivers for my Logitech Quickcam Pro 5000 which I learned is not supported for Windows 7

-A lot of Programs and Drivers try to tell you that they "Will Not Work" in Win 7 - But, in fact they DO. Case in Point: I'm using an old Visioneer 8100:

http://www.sevenforums.com/drivers/59069-installing-visioneer-onetouch-8100-scanner.html

I stumbled upon a means of actually installing the windows XP driver package for it!

The first BSOD also occurred before I had installed the ASUS drivers that came with the motherboard as well as the Radeon 4770 drivers. In addition I updated the firmware on the Crucial 64GB SSD drive that I use as the boot partition where Windows is installed.

Obviously, you got past the BSOD's? How, in Safe Mode? The Firmware Revision Probably helped?

The next 3 BSOD were all indicating disk.sys so I am a little concerned and don't know what could be wrong.

You know what I think - It may have been your external drives:

Hard Drives Crucial 64GB SSD
WD 1TB Caviar Black
WD 1TB External My Book II
I have since uninstalled the Logitech drivers, but I'm just not sure what could be the root of the problem. Attached is a zip file with the 4 .dmp files and also corresponding text files containing the debug analysis.

Any and all help is greatly appreciated!


I have right here an IO($)MEG()A 1 TB External HD - Which I had bought for a client and was using in a SERVER machine for extra storage... Needless to say, the drive, after about a month, begain to FAIL to be found on the USB Bus as the computer was booting - and in fact was preventing the system to BOOT- And when you unplugged it, the OS would boot right up, and stay up, and when you plugged the USB box back in, it then allowed you to Browse the drive.

But then about a week ago it just stopped working altogether- And while it was in THAT state, it was totally preventing my Server Tower from BOOTING. Eh! It was one of those problems where the solutions is SO obvious I got to kick my self in the buttocks! So when you take the faulty drive offa the USB Buss, the system fires up like drinking a snort of corn likker!

I've had similar problems with my external drives and/or USB ports on my machines.

What happens, is that while the USB drives are new and relatively unused, the system works great! But then, the external drives develope little errors, and that is when they interfere with the normal operation of the computer - They will cause BOOT HANGS, BSODs, UNEXPECTED REBOOTS... And all kindsa stuff.

So, you may want to CHKDSK your Ext Drives - You may even want to GWSCAN the drives- use GWSCAN version 5.12 - But make sure the External Drives are connected to an SATA Bus! Cos the program refuses to see USB paths. GWSCAN will actually REPAIR Hard Drive Errors that CHKDSK cannot touch.

Check out all those things, see if you are being affected by USB devices!

[EDIT] I just need to add that, although the specific problem I was describing here was on Windows Server 2003, I did see the same symptoms on Windows 7 when I brought that 1 TB Iomega drive home and plugged it in here - Win 7 refused to BOOT while I had the drive attached to the USB-bus.

Later, after I was able to run GWSCAN on the drive and then later CHKDSK - The system then booted normally.

Certai disk errors on a USB-Mounted disk will in fact cause the glitches that we are talkign about here- On Windows 2000, XP, Server, Vista OR Windows 7.

I finally have an Intel machine that has more than 8GB of Ram.
My ASUS M2N-SE AMD Windows 7 machine is back to Windows 7. Replaced the AMD 4400+ CPU and maxed out the RAM (4GB).
My Core Duo machine is only 2GB of Ram and it is locked to Windows XP in order to run Pro Tools 6.4, which I have been using since 2004.
I have one other Dell OptiPlex 980 tower, Identical to this one,
You should definately get a new PSU ASAP.

The graphic card you are using do require more power. You are using moderns components on your pc and a 500 watt power supply is not enough for what you are using. Nothing less than a 600 watt power supply would be required. A good 600 watt with at least 50 ampere on a single rail would be the best option for your system. Your 500 watt PSU probably does not have enough ampere.


Your graphic card, along with 2 regular HD and 1 SSD, that's a lot of power, count the CPU and your 4 gig of ram in.

You seriously need to remove at least 1 of your 2 HD if you want some stability, and until you change your PSU do not try to push your graphic card.

Thanks for your suggestion ManOwar2. Replacing the PSU is my last resort at this point given the cost and effort. I'm not straining the system by overclocking or doing anything extraordinary. The Radeon 4770 system requirements specify that a 500W PSU is sufficient. So given that I want to exhaust all other possibilities first.

After looking around a bit I found some information that indicated that some of the Asus driver and utility software, PC Probe II in particular, have been reported to cause problems. I uninstalled the versions I had which came with the CD packaged with the motherboard and installed the latest Win 7 64-bit versions.

I also found info saying that shutting off sleeping in the power plan has helped prevent these issues, so I went ahead and did that.

Before making these changes I had 2 BSODs yesterday, but nothing since making the changes. Will wait and see what happens now.

Does anyone else think that my system is under powered? I just hesitate to jump out and drop $100 on a new PSU and then have to almost completely disassemble my PC if I can avoid it. But I'll do what I have to do.

Thanks again for the very useful feedback!

Thanks for the info usasma!

So far I have not had another BSOD - knock wood - since I updated all of the Asus utilities and disabled sleep and hibernate from the power plan. I'm going on 3 days now with heavy usage on the PC, so I'm hoping that's a good sign. I've also upgraded my printer from the HP 1012 which is not supported in Windows 7. Among all of these things, something maybe was the culprit - maybe PC Probe II given what I've read from other users.
