Windows 7: Audio/video stutter/, attributed to tcpip.sys and ndis.sys DPC latency

Windows 7 Home 64 bit
Audio/video stutter/, attributed to tcpip.sys and ndis.sys DPC latency

Over the past week I have had serious audio/video stutter every few minutes for a second or two. It wasn't until last night I ran LatencyMon and discovered the drivers that have caused the issue. I have tried doing multiple diagnostic tests and many of them have come clean. I suppose that to provide more information on what has occurred, I will provide a timeline.

1. Experienced a BSOD right before shut-down due to "Page Fault Found In A Non Paged Area."
2. On the next boot, the keyboard plugged into one of my USB3 ports was not working, so I unplugged it and plugged it back in and it worked again.
2. It was after this BSOD that I began to experience the audio/video stutter issues.
3. Attempted to do tests on multiple pieces of hardware including CPU, RAM, and my various HDs. All seem to be okay (did not run MemTest but Windows Memory Diagnostic, however).
4. I thought it may have been drivers, so I tried updating my video/audio drivers.
5. Ran LatencyMon to discover that tcpip.sys and ndis.sys were the culprits. Updated motherboard/on-board network card drivers, but still experienced the freezing/stuttering
6. Plugged an already-faulty iPhone charger into the front USB port. Sparked and caused smoke to come out of cable.
6. Received a "0x0000001E" BSOD on shut-down a few days after the first BSOD.

To this day, the freezing/stuttering still continues. The one thing that astonished me, however, was that my laptop, over the past two-three days, are also experiencing the SAME exact symptoms. The same culprit for my laptop also appears to be the tcpip.sys and ndis.sys drivers as well.

I initially thought my desktop was acting up because of a possibly failing PSU, but it seems rather odd that my laptop is also experiencing the same exact symptoms as well.

I have moved into a new apartment with a router/modem already established in the apartment by my roommates, could this be the culprit for both computers? Or are both computers acting up for different reasons?

For the purposes of this post, I would like to prioritize fixing my desktop, but I find it highly suspicious that the same drivers are causing the same symptoms on TWO SEPARATE computers.

I hope you all don't mind a bump. 3 days later and I'm still having the problem. I have tried re-installing my Realtek internet drivers to inputting into cmd "netsh ip int reset." Does anyone have any ideas on what I can do to solve this?
