Win 7 Home Premium running On Dell Studio 1558 laptop (Intel i5 with 4G Ram).

About 50% of the time when I plug a usb device in (happens with different devices, different ports) I get a total system crash - not truly a BSOD here since it just looks like something is writing to graphics memory (odd patterns/colors on screen, etc). When I pull the USB device - the system reboots and comes up as normal (and sometimes will take the device that was just inserted fine!). :upset: Zip file with dump and perfmon attached (I hope)

Hi -

The 2 BSODs both name Acronis as the probable cause -
Code:
[font=lucida console]
snapman.sys  Sat Aug 15 04:42:00 2009 (4A8674D8)  - Acronis Snapshots Manager
[/font]
Remove Acronis.

I would also recommend that you update ATI video drivers -
Code:
[font=lucida console]
atikmdag.sys Wed Nov 18 14:14:44 2009 (4B0447A4)
[/font]
ATI video --> http://support.amd.com/us/gpudownload/Pages/index.aspx

Remove McAfee Internet Security --> http://jcgriff2.com/A-V_Removal_Tools/McAfee_Removal.html

If BSODs persist, run the Driver Verifier

Thanks for the uber rapid support !!!

Hi -

The 2 BSODs both name Acronis as the probable cause -
Code:
[font=lucida console]
snapman.sys  Sat Aug 15 04:42:00 2009 (4A8674D8)  - Acronis Snapshots Manager
[/font]
Remove Acronis.
Interesting - I had installed Acronis before I realized Win7 already had a system restore function. I removed it but the uninstaller clearly left something behind - I can delete the .sys file, but is there a cleaner way to pull it (given that the uninstaller did not work I dont have high hopes). Worst case I'll reimage the system from scratch... It will only take me a few hours to add on the stuff from the base image.

I would also recommend that you update ATI video drivers -
Code:
[font=lucida console]
atikmdag.sys Wed Nov 18 14:14:44 2009 (4B0447A4)

ATI video --> http://support.amd.com/us/gpudownload/Pages/index.aspx
Roger that - I'll do the update (wish between dell and microsoft someone had figured a way to do this automatically). WinUpdate is set to allow driver updates.

That one will need a bit of explanation.. Why would I remove the antivirus and firewall that came with (and I paid for) my dell? is it not compatible with win 7 (if so I will have an issue to take up with dell).


Thanks - will change things one at a time and see if it gets better...

Hi -

For Acronis, go into the Registry and disable the Acronis driver.

START | type regedit

- go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services
- scroll down to snapman
- 2x-click on snapman
- look for "Start"
- 2x-click on icon to the left of "Start"
- change the hexadecimal REG_DWORD to 4 (four) = disabled

McAfee removal is your call. I can only tell you from BSODs/ other that I have worked on over the years in Vista and Windows 7 that 3rd party firewalls are problematic and cause app hangs, app crashes and BSODs. McAfee is not alone - NIS, N360, KIS, etc. . . .

If BSODs persist, be sure to run the Driver Verifier as mentioned. Very important.
