BSOD diagnose, thanks

You are getting a very generic crash here, it's likely caused by a outdated or incorrectly installed driver, but it will more than likely take some trial and error to weed it out.

My first suggestion is going to be to remove comodo (all of it)
and start using MSE
http://www.microsoft.com/en-us/secur...s/default.aspx
As comodo is still using a outdated early vista based security driver and can cause problems like this.
It's very often something that pops up out of nowhere too, so it working before now doesn't remove it from scrutiny.

I see you are also running the AVG TDI driver.
You need to pick one security/malware software and stick with it. Two won't make you more secure, it will just lead to conflict and kernel lockups.
AVG is less likely to be the cause of your issue by itself since it's actually using a up to date system driver to run on. ...but all the same I would personally replace it with MSE also, just in the name of stability.

Get that little mess cleaned up for now, and get back to us.
If another crash occurs after fixing that mess please upload the newest memory dump as well, hopefully it will be less generic and more specific in nature.

Though it's completely possible just cleaning up the conflicting AV suites may clear up your problem.

Interesting note though I also noticed teamviewervpn.sys is loading, while looking back over it again to respond. This is apparently something to do with a network device you have. It's also not a valid windows 7 driver. I do not know of a update for it either...

tap0901.sys is loading and is a comodo driver though.
It could also be the open vpn driver, if that's the case it can be updated.
Downloads
Those are the only two possibilities for that driver though the comodo was more likely so I made an assumption there.
I still suggest removing AVG just for the purposes of troubleshooting this.

Yeah, both those drivers are 2008 and 2007, making them pre windows 7, and likely to be the cause of problems.
