Now that you mention it, the system was EXTREMELY laggy last night. I had Spotify open, and a Windows Virtual PC session with Win98, that only had 256MB RAM. I couldn't even open Google Chrome, it crashed every time I opened it! Even if I closed out of VPC, and rebooted the machine, it was laggy as heck!
Well, the memory dump blames a Windows driver - which wasn't tested for with our settings in Driver Verifier. What this means is that it's either a Windows problem (not real likely), or a hardware problem (which includes compatibility issues, low-level driver problems, and even malware).
IMO, it's due to the wireless USB device.
Try temporarily using a wired connection (and uninstalling/removing the wireless USB device) to see if that stops the BSOD's.
Please see the drivers below in RED. They are from 2008 - which was before Win7 was released. They must be updated. If you can't find updates, then they've gotta be removed from the system.

The following info is just FYI, I've already addressed the issues that I saw in the above paragraphs:
3RD PARTY DRIVERS PRESENT IN THE DUMP FILES
- Create a System Restore Point prior to doing any of this. DO NOT mess with the drivers themselves - leave the Windows\System32\drivers directory alone unless we specifically direct you to it!
- Please either update the older drivers from the device manufacturer's website - or uninstall them from your system. Reference links are included below.
- DO NOT use Windows Update or the Update Drivers function of Device Manager.
- Please feel free to post back about any drivers that you are having difficulty locating.
- Windows Update exceptions may be noted below for Windows drivers.

Well, the easiest thing is to carry your computer down to the basement and put it next to the router for a couple of days.
If this proves that it's the wireless device, then you'll need to get a wireless device that plugs into your motherboard in order to have wireless upstairs.
Just got another C9 BSOD! It said the problem was with CLASSPNP.SYS. Photo below.
That's the same one that was blamed with the other memory dump.
We're sure that the Driver Verifier isn't pointing out a 3rd party driver - so it's time to shut it off.
To do this, open up Verifier and select "Delete existing settings", then click on "Finish"
Reboot the system for the changes to take affect.
It's most likely a hardware error.
And the most likely piece of hardware is the wireless USB device.
Well, I guess I'll be buying a PCI-Express card then.
Do you have any recommendations? I would prefer a card with 802.11N. 5GHz is preferred, but not needed. I found this card on Newegg. Does this look good?
Rosewill RNX-N250PCe (RNWD-11005) Wireless Adapter IEEE 802.11b/g/n
Something that's under $30 would be preferred.
Don't just go out and buy stuff on my say-so! I'll be really embarrassed if it doesn't work!
Test it first by running it without the device - if that stops the BSOD's, then you can go out and spend money.
Frankly, I buy the cheapest wireless card that I can find - I don't need anything fancy.
I'd check in some Gamers forums to see what they recommend.
