Windows 7: BSOD Win7. No issue in SafeMode/Networking, crashes 2 min after login

BSOD Win7. No issue in SafeMode/Networking, crashes 2 min after login

Dell Studio XPS w/ 6GB RAM. Has been running fine for 2 years.
Yesterday, started giving a BSOD of IRQ1_LEVEL_LESS_THAN_OR_EQUAL.

No issues when running in SafeMode w/ networking, but when logging in in normal mode, about 2 minutes after doing the login, it crashes EVERY TIME.

- I've rolled back to a restore point from 1 week ago. No luck.
- I've tried to analyze the crash files myself using WinDbg, but I've not found anything interesting (though it is likely my lack of skill at using WinDbg).
- No issues in Safe Mode or Safe Mode w/ Networking

Trying to avoid a reinstall of the OS, but wanted to see if anyone could help interpret the crash files. My guess is that it is a 3rd party driver that is causing the crash, but need help identifying which one, if possible. Not sure why it would start yesterday afternoon for some unknown reason.

Any help would be appreciated. Dump files are attached

From your crash logs:

Usual causes:  Kernel mode driver, System Service, BIOS, Windows, Virus scanner, Backup tool, compatibility
Please uninstall the programs Acronis / Acronis true image.

Looks like you recently installed very old webcam software?
It is this driver which is contributing to your BSOD's:

Driver: P0630Vid.sys
Dated: Fri Nov 11 05:55:57 2005
Refers to: Creative Labs WebCam driver
Uninstall the program, then re-install.
Update web-site: Creative Worldwide Support

Also Update these drivers:

Apple iPod/iPhone Mobile USB device driver

Driver: k57nd60a.sys

Thanks for your help:

1. Removed Acronis True Image. No change (e.g. still crashing)
2. Removed Creative WebCam software and driver. No change. (Don't think they make a Win7 driver for my webcam so I might have to go get a new one)
3. Updated the Broadcom Driver. Stable so far . . . .
4. Unable to run the Dell Driver Manager program due to it complaining about needing .NET 4 - yet I have .NET 4 installed.
5. Unable to figure out how to refresh the iPod USB driver.

But, things appear stable/resolved as of #3, so I'm going to watch things for a couple of days and confirm.

Greatly appreciate the help.

The analysis is somewhat inconclusive and is not showing cause or any misbehaving drivers.
Usually a ntkrnlmp.exe fault points to memory or harddrive issues (see tests below)

Update the BIOS if possible, you already have Version A06 installed,
but looks like it may have been revised on a later release:

  BIOS Version                  A06

OK. I ended up re-installing Win7 back to a vanilla install.
I installed Avast Anitvirus immediately and it started saying "URL.Mal" virus and blocking outbound requests. So, I was obviously infected with something.
MalwareBytes found some Trojan viruses on my sons' Internet Temp Files from the old installation and cleaned them.
Still getting URL.Mal popups. No other virus signatures found. Still crashing in normal mode.
Finally downloaded and ran aswMBR and it detected a RootKit Virus, but could not clean it.
Installed MalwareBytes RootKit Detector Beta and it was able to clean the virus off my machine.
Several virus scans of Avast, MalwareBytes, TrendMicro ATTK and a couple of other different virus/RootKit scanners later, and I am now virus (and crash) free.

Closing as solved, but the root of my BSOD crashs was a RootKit virus. I greatly appreciate the crashfile analysis help from the community. Thanks to all.

Ahhhh....And if you had just followed my advice in post #5 and scanned for viruses,
then a re-install of Win 7 wouldnt have been neccessary

Glad its now sorted :)

Please mark the thread as solved thanks.
