new bsod's after moving from xp to win 7

I've been running Windows 7 for over a week now and I've had like 7 bsod's at random (browsing internet, playing pc game, even while idle afk)

- Windows 7 Home Premium 64 bit build 7600. (program files labeled x86)
- brand new copy of OS, purchased from newegg, installed myself.
- first time install, on brand new fresh 1 terabyte samsung spinpoint harddrive.
- all other hardware except the new harddrive is about 18 months old, which ran on win xp error-free with no previous bsod problems.

.dmp files attached

I uninstalled Zone Alarm, rebooted, ran a full virus scan, came up clean.
Things were going okay today but I just got a new BSOD while trying to open a video link in explorer.

I'm back with a new BSOD. I noticed my videos in explorer weren't buffering well, which sometimes happens when my pc has been running for long periods, and is fixed with a reboot. When I closed out the browser, the program stopped responding and I quickly met another BSOD.

Files attached.

Note that I uninstalled the avg since the last BSOD.

As for my logitech webcam drivers being old. Its an old 4000 model and doesn't support windows 7, so I was instructed to force it to update with vista drivers and fool it into thinking they were windows 7 drivers in order to get the webcam to work with windows 7, and thats why the drivers are old. Is it causing the bsod's? If so I'd get rid of the webcam.

In analyzing part 3 it clearly states memory corruption. That combined with the fact it gets worse over time and is cured by a reboot makes me think that is the problem. It may well be a driver causing the memory corruption but running memtest will tell you which.

I dont know if you have run memtestx86 to test you memory but it cant hurt and may help. It will take a bit of time

I would run memtest

Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Boot from the CD, and leave it running for at least 5 or 6 passes.

MmUnlockPages twice with the same list, etc).  If a kernel debugger is
available get the stack trace.

So far it seems that the webcam was the true BSOD culprut. No crashes since uninstalling it and those vista drivers I rigged it with.

I haven't gotten around to running the memtest but I do have a question about that in response to the above post about memory corruption. I have recently been playing a beta game that has known memory leak issues in its code, which eventually causes the game to crash due to running out of memory.

Would that leak effect other things running outside of the game, like video buffering in a web browser for example? Either way I will run the memtest when I can make time. Right now I've been bombarded with week 1 of Fall semester homework. Thanks for the help.
