i used the SF Diag Tool V3 that i downloaded from the forums since my last BSOD. not sure what to include so i got everything i could with the tool. however, there was an error accessing my event logs. there are the event files in the attachments though.

Please help me out. any help is much appreciated!

Unfortunately, the Windows Debugging Tools aren't able to access symbols for your operating system files (in particular NTOSKRNL.EXE / NTKRNLMP.EXE / NTKRNLPA.EXE / NTKRPAMP.EXE) from the Microsoft Symbol Server - so that makes debugging them difficult if not impossible.

Please do the following (this will not affect the analysis of the current files - but it may help later files that are acquired):
- activate/validate the Windows installation at Genuine Microsoft Software
- run sfc.exe /scannow to replace any problem files
- open a support incident with Microsoft to see if they can fix the missing symbols issue ( Windows 7 Solution Center )
- If that doesn't fix it, then wipe the hard drive and reinstall Windows
- don't use "leaked"/torrent builds

So, let's start with what we do know:

First -
Anti-Virus Removal:
Please do the following:
- download a free antivirus for testing purposes: Free AntiVirus
- uninstall the Norton from your system (you can reinstall it, if so desired, when we're done troubleshooting)
- remove any remnants of Norton using this free tool: KB Article Not Found
- IMMEDIATELY install and update the free antivirus
- check to see if this fixes the BSOD's

Next -
There is a driver named safedrv.sys involved in the crash also.
Please remove the program and test for further BSOD's
If you can't remove the program, then go to C:\Windows\System32\drivers and rename safedrv.sys to safedrv.BAK

Then test for further BSOD's.

my antivirus is Symantec Endpoint Protection. it came free installed as a package into my laptop. i bought this laptop from an IT fair in my school for school purposes, so there was a configuration to install essential programs specifically for my coursework.

btw, how do you test for BSOD's? just wait and see if anymore BSOD's pop up?

-EDIT-
i did a validation of my OS and it's genuine. and i also updated my Symantec anti-virus. does that help?

Hopefully the update will help. If not, the next step is to remove it completely.

The true test for BSODs is just waiting for them, but if you want to try to expedite them, you can enable driver verifier: http://www.sevenforums.com/tutorials/101379-driver-verifier-enable-disable.html

Unless you are in a hurry, such as you need to make sure your computer is stable before you leave for school, I would advice just using your computer normally.
