multiple random bsod on dell laptops


I started to get several random BSOD - there are days when all is OK but others when i get 3 or 4 Bsod. I have attached 4 mini dmp files files for some of these bsod. I have updated all drivers on my dell e7440 using dell command update tool but the problem persists. Any help would be much appreciated. i have a suspect .... but i don't want to lead you to a wrong path.

i'm running win 7 x64

Many Thanks

out of the 4 dump files sent in, 3 blame Norton AV as the culprit whilst the fourth blames a windows process which is network related so could also be linked to Norton.
Try removing Norton using their removal Tool:

I notice you also have another anti virus product running too:
ImmunetNetworkMonitor.sys Thu Jul 03 00:15:11 2014: Immunet Plus AV

It's quite possible that Norton and Immunet AV were clashing hence the bsod but the only way to find out is to test by removal.

Personally I'd remove both and stick with a combination of MSE and Malwarebytes. This is an effective not to mention free way of keeping your machine bug free:

If you'd rather keep Norton I first try removing the Immunet and see if the bsod stops. If it doesn't then try removing Norton (don't forget to use the tool).
You could then try adding Norton back after running this scan.
Find command prompt if the start menu, right click on it and run as admin. Type:
sfc /scannow
Press enter and await results.

Post any new dump files.
