2 new HP Pavilion notebooks with 7 Home Premium pre-loaded with Norton. My first act was to use the Norton Removal Tool and load ZoneAlarm free and AVG Free. Frequent random BSOD's ever since...I found my way into Debug and have had various reports regarding ntoskrnl, depending on the status of symbols. It's been many years since I played with (DOS 3.x) debug, so this has been a considerable fumble. Excerpts follow and any insights would be greatly appreciated, as I am not a developer:

UNEXPECTED_KERNEL_MODE_TRAP (7f) This means a trap occurred in kernel mode, and it's a trap of a kind that the kernel isn't allowed to have/catch (bound trap) or that is always instant death (double fault). The first number in the bugcheck params is the number of the trap (8 = double fault, etc) Consult an Intel x86 family manual to learn more about what these traps are. Here is a portion of those codes: If kv shows a taskGate use .tss on the part before the colon, then kv. Else if kv shows a trapframe use .trap on that value Else .trap on the appropriate frame will show where the trap was taken (on x86, this will be the ebp that goes with the procedure KiTrap) Endif kb will then show the corrected stack. Arguments: Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT Arg2: 0000000080050033 Arg3: 00000000000006f8 Arg4: fffff80003095e58

I tried running Rootkit Revealer but I don't think it works on x64 systems. Similarly Blacklight seems to have aged off. I'm running Sophos Anti-Rootkit now. So far so good...

There is a known conflict in running both AVG and Zone Alarm. If you Google "avg zonealarm" (without quotes) you will see quite a few links. I uninstalled AVG and then reinstalled AVG but without the Link Scanner component and that solved my problem.

Superb! I went the other direction and nuked Zone Alarm in favor of Comodo because I wanted to keep Link Scanner. Leak Test and Shields Up gave the same perfect results and my system has been stable for several hours. Now I'd better fix up my wife's system or she will be really annoyed. :) Thanks a bunch! –  user38052 May 24 '10 at 4:21

BSODs are almost always either hardware or driver issues.

Given you removed Norton, maybe some aspect of some Norton driver was left, just enough that certain occasional kernel operations are failing.

You have two options: try and clean up manually, or re-pave. The latter is likely to be much easier and more reliable.

I suspected remnants and previously searched my registry for Norton. Finding none, I continued searching for answers. Thank goodness for this site and thank you for taking the time to reply. I guess I'd better go buy some DVD's and create a backup in case I need to re-pave someday. –  user38052 May 24 '10 at 4:36
